Pseudolunularia gen.n. (Cheilostomata), a IunuIitiform bryozoan from the Indo‐West Pacific
Authors: CADÉE GERHARD C. , CHIMONIDES PANTELAKIS D. J. , COOK PATRICIA L.
Published: July 2005

A new genus of anascan lunulitiform bryozoan, Pseudolunularia. is introduced for two new species, P. enigma and P. unguis. It is inferred that live colonies both possess basal rhizoids and are supported and stabilized by elongate avicularian mandibles. The autozooids, brooding zooids and avicularia of both species bear a striking resemblance to a parallel pair of species belonging to the genus Lunularia, L. repandus and L. cupulus.
New gastropods from East Pacific hydrothermal vents
Authors: WARÉN ANDERS , BOUCHET PHILIPPE
Published: July 2005

The following new prosobranch species are described: Cyuthermia (gen.n.) naticoides, Lucunoidc (gen.n.) exquisitus (Neomphalidae); Peltospira Iamellifera, Pachydermia (gen.n.) laevis, Depressigyra (gen. n.) g1obulus. D. plunispira, Solutigyra (gen. n.) reticulata, Lirapex (gen. n.) humata, L. granularis (Peltospiridae); Bathymargarites (gen.n.) symplector (Trochidae) and Provanna mucleani (Littorinoidea). Shells and soft parts of the species are described and figured. One species each of Sinezona (Scissurellidae), Moel1rriopsis (Seguenzoidea) and Phymorrhynchus (Turridae) is recorded from East Pacific hydrothermal vents, but not identified to species. Information about feeding biology and type of larval development is given for most of these species. The systematic position of the new species of Neomphalidae and Peltospiridae is considered uncertain, but further anatomical investigations are in progress. The gastropod fauna of East Pacific sulphide‐rich environments is summarized and composition, endemism, age. dispersal, predation, adaptations and feeding biology are discussed.
Remarks on Araphura Bird & Holdich (Crustacea, Tanaidacea) and allied genera, including descriptions of three new species
Authors: SIEG JÜRGEN , DOJIRI MASAHIRO
Published: July 2005

A key for the three closely rclatcd genera Aruphura, Arhapuroides and Tanaella is provided and the taxonomic differences are discusscd. For Araphura and Arhapuroides a key to the specics is also given, while for Tanuellu one is available elsewhere. Within Arhuphuroides, the taxonomic position of A. hrevispina is discussed and A. septentrionalis sp.n. is described. Within Araphura, the analysis of the postmarsupial stages in A. higginsi sp.n. indicates a saltatorial growth of the pereaeonites from neuters to females. Therefore, the shape of the pars molaris and the structures of uropods are the main taxonomically useful characters. The second species described as new in the genus, A. joubinensis sp.n. has formerly been recorded as A. brevimanus from Antarctic waters. Finally, based on material from Great Britain, a redescription of the type species, A. brevimanus, is presented.
Two new genera and species of Braconinae (Insecta, Hymenoptera, Braconidae)from Brunei

Published: July 2005

Fuvihracon gen.n. (typc‐species: Fuvibracon gauldi sp.n.) and Spurhulibrucon (type‐species: Sparhulibracon dayi sp.n.), both lrom Brunei, are described and illustrated. The relationships of the two new genera and of the Carnpyloneurus Szépligeti and Chelonogaslra Ashmead generie groups are discussed.
New species and new records of apodous holothurians (Echinodermata, Holothuroidea) from southern Africa
Authors: THANDAR AHMED S. , ROWE FRANK W. E.
Published: July 2005

Oestergrenia spatula sp.n. from the south coast of southern Africa and Leptosynapta naiga sp.n. from the east coast are described. The genus Oestergrenia Heding, 1931 is resurrected from synonymy and discussed in detail. Epitornapta knysnaensis Cherbonnier, 1952 is referred to the genus Leptosynapta. Leptosynapta ancoracuta Cherbonnier, 1954 is considered a synonym of L. knysnuensis. In addition, two new records of Euapta godeffroyi (Semper, 1868) and Chiridota rigida Semper, 1868. both from the east coast, are given.
Histologic studies of ostracoderms, placoderms and fossil elasmobranchs. 6. Hard tissues of Ordovician vertebrates
Authors: ØRVIG TOR
Published: July 2005

Size and distribution of dermal elements in Ordovician eriptychiids and astraspids are considered relative to phases of skeletal assimilation and regression. The phyletic significance of acellularity in aspidin is discussed, as also is the alleged relationship claimed to exist in initial developmental stages between that hard tissue and dentine proper. To judge from hard tissue histology the astraspids may not, like the eriptychiids, have belonged to the heterostracans but to another group, of early agnathans, still incompletely known.
Six new species of Protodrilus (Annelida, Polychaeta) from Europe and New Zealand, with a concise presentation of the genus
Authors: VON NORDHEIM HENNING
Published: July 2005

Protodrilus haurakiensis sp.n., P. jouinae sp.n., P. jägersteni sp.n., P. submersus sp.n. and P. litoralis sp.n. from New Zealand and P. gracilis sp.n. from Europe are described. Protodrilus jägcrsteni, P. submersus and P. litoralis are sibling species. Sperm dimorphism in all species investigated by the author is recorded for the first time in polychaetes. Two of the three so‐called ‘ecological forms’ of P. hypoleucus and P. adhaerens are classified as variations of the type species without a particular taxonomic rank. In a table the partly actualized data of all 30 known Protodrilus species are presented, 8 of which are very insufficiently described. Synonyms in Protodrilus and similarities between P. rubropharyngeus Jägersten and P. flavocapitatus Uljanin are mentioned.

Authors: FJELDSÅ JON , KRABBE NIELS
Published: July 2005

A previously unpublished collection of birds from the Bolivian highlands, consisting of 5426 specimens of 351 taxa, was examined. The material, housed in the Swedish Museum of Natural History, includes the first records from Bolivia of Phyllomyias sclateri subtropicalis, Saltator aurantiirostris albociliaris, Sicalis citrina and At1apetes rufinucha melunolaemus, the first records from the department of La Páz of Synallaxis frontalis and Anthus hellmayri, and noteworthy altitudinal records for Plegadis chihi, Brotogeris versico1orus, Chloroceryle americana, Lepidacolaptes angustirostris, Synallaxis frontalis, Thamnophilus doliatus, T. ruficapillus, Conopophaga ardesiaca, Pachyramphus versicolor, Cnemotriccus fuscatus, Stigmatura budytoides, Mionectes macconnelli and Turdus albicol1is. Morphological and systematic remarks are given for a few species.
Eutherian mammals from the Early Cretaceous of Mongolia
Authors: KIELAN‐JAWOROWSKA ZOFIA , DASHZEVEG DEMBERLYIN
Published: July 2005

A collection of eutherian mammals consisting of 39 specimens (teeth and jaw fragments) from the ?Aptian or Albian Khoboor Beds in the Gobi Desert, Mongolia, is described. It contains 3 taxa: Prokenna1estes gen.n., assigned to the Otlestidae Nessov, new rank, with 2 shrew size species; P. trofimovi sp.n. and P. minor sp.n.; a heavily worn larger lower molar which will be described elsewhere. It cannot be excluded that P. trofimovi and P. minor are only sexual morphs within the same species. Prokennalestes and Bobolestes Nessov are possibly the oldest known eutherian mammals, but Prokennalestes is morphologically more primitive than Bobolestes. It has a labial mandibular foramen, 5 premolars and 3 molars, 3 cusps in parastylur region, paracone larger than metacone, unwinged conules, no pre‐ and posteingula, and lower molars with a 3‐cusped talonid, which is narrower than the trigonid, Otlestes and Kennalestes may be derived with little modification from Prokennalestes. Prokennalestes gen.n. is congeneric with Prokennalestes Trofimov and Prozalambdalestes Trofimov, which are both nomina nuda.
New Antarctic holothurians (Echinodermata) – II. Four species of the orders Aspidochirotida, Elasipodida and Apodida
Authors: GUTT JULIAN
Published: July 2005

Four new species of antarctic holothurians are described: Bathyplotes rubipunctatus sp.n. Bathyplotes fuscivinculum sp.n. (both Aspidochirotida), Achlyonice violaecuspidata sp.n. (Elasi‐podida) and Paradota weddellensis sp.n. (Apodida). The genus, Bathyplotes, is redefined. The material was mainly collected from the continental shelf of the southern and eastern Weddell Sea, at depths between 225 and 840 m. The systematic status of these new species within the genera, as well as relationships to other species and higher taxa are discussed.
Sperm ultrastructure in Myxinidocotyle and Acanthocotyle (Platyhelminthes, Monogenea, Acanthocotylidae)
Authors: MALMBERG GÖRAN , AFZELIUS BJÖRN A.
Published: July 2005

Spermatozoa of Myxinidocotyle californica from the hagfish Eptatretus stoutii and of Acanthocotyle lobianchi from the skate Raja clavata show a similar ultrastructure: two axoncmes of the 9 + 1 type in parallel with the nucleus‐and one mitochondrion. In the released Acanthocotyle spermatozoa nucleus and mitochondrion both have a triangular cross‐section. No cortical microtubules are present. The ultrastructure of these two acanthocotylid spermatozoa thus corresponds to sperm pattern 2 according to Justine et al. (1985). This pattern is derived from the more primitive pattern 1, which in the Monogenea is found only in the Oligonchoinea Bychowsky, 1937 or the Polyopisthocotylea sensu Justine et al.
Antygomonas incomitata gen. et sp.n. (Cyclorhagida, Kinorhyncha) and its phylogenetic relationships
Authors: NEBELSICK MONIKA
Published: July 2005

A new genus and species of Kinorhyncha from the Bay of Vestar (northern Adriatic Sea) is described. The single male specimen was collected from suhtidal medium‐grained sand. Autapo‐morphies of Antygomonas incomitata gen. ct sp.n. are the occurrence of 32 interstitial placids, three lateral spines on the 10th zonitc, the subdorsal sculpture on the 12th zonitc, two mid‐dorsal spines on the 13th zonitc, and a special cuticular formation of the trunk zonites 4‐13 which show a mid‐ventral articulation zone but no lateral ones. The relationships of Antygomonas incomitata within the Cyclorhagida are discussed. The term zonite (instead of segment), introduced by Zelinka (1928) for the repetitive arrangement of the cuticle, epidermis, nervous system, sense organs, and muscles in Kinorhyncha is discussed.
A new genus and species of the Syllidae (Annelida, Polychaeta) from south India
Authors: WESTHEIDE WILFRIED
Published: July 2005

A syllid species new to science is described from intertidal sandy sediments on the cast coast of India, for which a new genus is erected: Psammosyllis aliceae gen. et sp.n. Incorporation into either the Eusyllinae or the Exogoninae is unresolved, because it possesses characters of both of these poorly defined subfamilies.
Sperm structure in the scissurellid gastropod Sinezona sp. (Prosobranchia, Pleurotomarioidea)
Authors: HEALY JOHN M.
Published: July 2005

Spermatozoa of Sinezona sp. (Scissurcllidac) arc examined ultrastructurally and compared with spermatozoa of other vetigastropods. Sinezona sperm are characterized by the following features: (1) a squat‐conical acrosomal vesicle; (2) subacrosomal deposits–one forming a perinuclear sheath and the second forming a rod which almost penetrates the nucleus; (3) prominent nuclear invaginations enclosing the axial rod and centriolar regions; (4) a midpiece consisting of axoneme surrounded by a single, sleeve‐like mitochondrion; (5) an annulus occurring posterior to the midpiece; and (6) a flagellum. Spermatozoa of Sinezona sp. are clearly modified in structure in comparison with spermatozoa of other pleurotomarioids and, more generally, most other vetigastropods (these retain multiple, spherical mitochondria and, with rare exceptions, do not have the ccntrioles located in a nuclear invagination).
Morphology of the mandibles in the millipedes (Diplopoda, Arthropoda)
Authors: KÖIUHLER HEINZ‐RÜDIGER , ALBERTI GERD
Published: July 2005

The mouthparts of seven species from five families of Diplopoda have been investigated with scanning electron microscopy. The distal segment of the mandible, the gnathal lobe, is the most complex structure. Although the biting and crushing parts among the examined genera arc always based on the same general scheme, typical modifications of these structures exist which are regarded to be taxon‐specific. The density of the teeth on the pectinate lamellae appears to determine the size of the ingested food particles. A well‐developed anterior fringe does not seem to be necessary for the ingestion of food.
Ultrastructure of the sense receptors of adult Multicotyle purvisi (Trematoda, Aspidogastrea)
Authors: ROHDE KLAUS
Published: July 2005

The following presumptive sense receptors of adult Multicotyle purvisi from the intestine of freshwater turtles in Malaya are described by transmission electron microscopy: disc‐like receptor with many electron‐dense collars and modified ciliary rootlet forming a ‘disc’; non‐ciliate receptor with long rootlet; non‐ciliate receptor with branching rootlet and dense mass of irregularly arranged microtubules; non‐ciliate receptor with rootlet fanning out from basal body, cross‐striated in its upper and with electron‐dense structures in its lower part; uniciliate receptor with thick layer of cytoplasm around axoneme; receptor with short cilium, at base of deep invagination of tegument; receptor with short cilium terminating in an electron‐dense apical cap; and uniciliate receptor with long cilium. In addition, there may be a small non‐ciliate receptor with a long ciliary rootlet at the base of the thick dorsal tegument, and uniciliate receptors differing from the uniciliate receptor with long cilium in the number of electron‐dense collars and the length of the cilium and ciliary rootlet. Implications of the findings for the phylogeny of the parasitic Platyhelminthes and for evolutionary trends within that group arc discussed. The considerable degree of divergence of receptor types between the species of one family is attributed to the archaic nature of the group.
Kakoeca antarctica gen. et sp.n., a loricate choanoflagellate (Acanthoecidae, Choanoflagellida) from Antarctic sea ice with a unique protoplast suspensory membrane
Authors: BUCK KURT R. , MARCHANT HARVEY J. , THOMSEN HELGE A. , GARRISON DAVID L.
Published: July 2005

A new genus and species of loricate choanoflagellate, Kakoeca aniarctica Buck & Marchant gen. et sp.n. grown in rough culture from an Antarctic sea ice innoculum is described. This organism has a distinctive lorica morphology consisting of more than 200 costal strips arranged in transverse and longitudinal costae that arc perpendicular to one another in the posterior portion of the lorica. The transverse costae show declination with respect to the lorica axis in the anterior part of the lorica. The cell is suspended in the lorica by a robust protoplast suspensory membrane. This membrane blocks water flow from the posterior of the lorica necessitating water entry through the side of the lorica, an area where the maximum sized apertures in the lorica are found. Terminology (lorica lining and protoplast suspensory) is suggested for the two types of lorica membranes which have been found associated with loricas.
Terga1 and inter–tergal metasomal glands of male braconine wasps (Insecta, Hymenoptera, Braconidae)
Authors: QUICKE DONALD L. J.
Published: July 2005

The distribution of cxocrine tergal and inter–tergal glands among males of more than sixty genera of Braconinac has been surveyed. The morphology of the glands and their reservoirs is described. Two gland types were found. Large, sac–like inter–tergal glands, usually most prominent between the 7th and 8th abdominal tergites, were found in all members of the Braconini, Adeshini, Aphrastobraconini, Glyptomorphini and the Atanycolus and Merinotus groups of genera. Inter–tergal glands were generally considerably smaller in members of the Bathyaulacini, Coeloidini. Euurobraconini and Iphiaulacini. Small pore–plate, vase–like or tubular tergal glands opening on the medio–lateral or antero–lateral selerotized parts of the 8th metasomal tergite were found in many genera, but were largely absent from members of the Braconini, Euurobraconini and Iphiaulacini ss. The phylogenetic implications of these findings are discussed.
Arenonemertes arenicolus sp.n. (Nemertea) from the Swedish west coast, with notes on the genus Arenonemertes
Authors: HYLBOM RICHARD
Published: July 2005

Arenonemertes arenicolus sp.n. is described from the Gullmar Fjord, Sweden. It differs from A. microps Friedrich, 1933 in: (1) lacking cephalic glands, (2) having an undivided caecum on the midgut, whereas the caecum is divided into three lobes in A. microps, and (3) the position of the nephridial ducts in relation to the lateral nerves (dorsal instead of ventral). Arenonemertes microps is still considered a valid species, but it is poorly described and the type material has been lost.

Authors: GIBBONS LYNDA M. , KEYMER I. F.
Published: July 2005

Tunqua tiara (von Linstow, 1879) Blanchard, 1904 from the stomach of the Nile monitor lizard (Varunus niloticus) in Nigeria is redescribed in detail using both light and scanning electron microscopy. Its mode of attachment and host pathology are described and discussed. A list of hosts and localities from which T. tiara has been recovered is included.
New species, anatomy, and systematic position of the hydrothermal vent and hydrocarbon seep gastropod family Provannidae fam.n. (Caenogastropoda)
Authors: WARÉN ANDERS , PONDER WINSTON F.
Published: July 2005

The anatomy of the hydrothermal vent gastropod Provanna is described. It is shown to be a primitive neotaenioglossan with mainly plesiomorphic features in all systems, including open pallial gonoducts, epiathroid nervous system with accessory pedal ganglia and a circulatory system where a considerable portion of the venous blood from the coelomic spaces enters the pallial skirt. Apomorphic features include the possession of an anterior notch, or short canal in the shell (and mantle edge), an annulated sensory pallial tentacle, paraspermatozoa modificd as nurse cells. multiple seminal receptacles, a posterior bursa copulatrix, and a renal oviduct with three distinct regions. the middle one expanded. Comparisons are madc with Abyssochrysos, a genus assumed to be a relict member of the Loxonematoidea, which appears to be the closest known relative. A new family. Provannidae fam.n., is created and tentatively included in the Loxonematoidea. The following new specics are described: Provanna segonzaci sp.n. (from hydrothermal vents at the Fiji Back Arc), P. laevis sp.n. (from hydrothermal seeps in the Gulf of California), P. sculpta sp.n. and P. admetoides sp.n. (from hydrocarbon seeps in the Gulf of Mexico). New records are added for previously described species of Provanna.
Mouthpart and foregut ontogeny in larval, postlarval, and juvenile spiny lobster, Panulirus argus Latreille (Decapoda, Palinuridae)
Authors: WOLFE STEVEN H. , FELGENHAUER BRUCE E.
Published: July 2005

The spiny lobster Panulirus argus has a life cycle consisting of a long‐term (∼9‐12 months) planktonic larval period with 11 larval stages (the phyllosoma), a short (<1 month?) planktonic‐to‐benthic transitional postlarval stage (the puerulus), and benthic juvenile and adult phases. The mouthparts and foregut during these stages were examined and described by means of scanning electron microscopy (SEM) in an investigation of the species' developmental morphology, diet, and ecology. The phyllosoma mouthparts close to the esophagus are the labrum, mandibles, paragnaths, and first maxillae. The second maxillae and first and second maxillipeds are increasingly distant from the esophagus as the larva develops. The pair of asymmetrical mandibles bear many teeth and spines, and the molar processes form what appears to be an intricate toothed shear. The mandibles remain similar throughout the phyllosoma stages. During the molt into the puerulus, the mouthparts are greatly changed, and the second maxilla and the three maxillipeds join the other mouthparts near the esophagus. However, the transformation appears incomplete, and many of the mouthparts are not fully formed until the molt to juvenile completes their development. The phyllosoma foregut lacks a gastric mill and has but one chamber. In addition, the first two stages lack a gland filter. During the molt to puerulus, the foregut is greatly changed and subsequently is similar to typical decapod foreguts in having an anterior cardiac and posterior pyloric chamber. Only rudimentary internal armature is present. Following the molt to juvenile, the foregut is quite similar to that of the adult, which exhibits a substantial gastric mill. The 11 phyllosoma stages were separated into two groups (group A = stages 1‐5, group B = stages 6‐11) on the basis of changes in both mouthpart and foregut morphology. The puerulus has never been observed to feed. Nothing was observed in our investigations that would prevent feeding, though both mouthpart and foregut development appeared incomplete. The mouthpart and foregut structures of larval, postlarval and juvenile P. argus differ widely, possibly reflecting the extreme modifications for different habitats found among these life phases.

Katacephala Crawford comprises six species, grandiceps Crawford (the type species), tenuipennis Tuthill, arcuata Crawford, psidii (Tuthill) comb.n., cinctata sp.n. and anomala sp.n. Jenseniella Tuthill is synonymized with Katacephala. Katacephala fasciata Jensen is synonymised with K. arcuata Crawford. Known host‐plants are all Myrtaceae. Allophorina comprises two species, lobata sp.n. (the type species) and una sp.n. Its host‐plant relationships are unknown.
Ultrastructure of the flame bulbs and protonephridial capillaries of Prorhynchus (Lecithoepitheliata, Prorhynchidae, Turbellaria)
Authors: ROHDE KLAUS , WATSON NIKKI
Published: July 2005

The flame bulb of Prorhynchus is formed by a single cell. Its nucleus is not located in the cytoplasm at the base of the flame. Cilia of the flame have cross‐striated hollow ciliary rootlets converging towards their tips. The maximum number of cilia counted was 13. The weir consists of a single row of longitudinal ribs that contain longitudinal filaments and possess regularly arranged protrusions along their surface appearing as transverse bands in horizontal section. A ‘membrane’ of extracellular material extends between the ribs. and loose material fills the places between the ribs, with a denser layer midway between adjacent ribs. Distally, the ribs fuse to form a continuous tube without a junction. Small protonephridial capillaries lack junctions, larger ducts have lateral flames and patches of long microvilli. Large excretory ducts open into a ciliated and lamellated cavity which is connected by a narrow canal to the excretory pore. The terminal part of the canal close to the pore possesses many cilia and microvilli. Phylogenetic implications of the findings are discussed.
Gnathostomulida from Fiji, Tonga and New Zealand
Authors: STERRER WOLFGANG
Published: July 2005

Of 54 species of Gnathostomulida known to date, only six have been reported from the Pacific Ocean. This paper describes 18 species of Gnathostomulida from the Pacific islands of Fiji. Tonga and northern New Zealand. Of these, three are species previously described from the northeastern Atlantic and Mediterranean: Haplognathia ruberrima (Sterrer 1966), or the northwestern Atlantic: Haplognathia rosacea (Sterrer 1970) and Pterognathia ctenifera (Sterrer 1970). Fifteen species are new to science, including three that represent two new genera: Cosmognathia arcus gen. et sp.n., Cosmognathia bastillae sp.n., Pterognathia crocodilus sp.n., Pterognathia vilii sp.n., Agnathiella sp., Tenuignathia vitiensis sp.n., Ratugnathia mukuluvae gen. et sp.n., Gnathostomula salotae sp.n., Gnathostomula raji sp.n., Gnathostomula maorica sp.n., Austrognathia singatokae sp.n., Austrognathia nannulifera sp.n., Austrognathia novaezelandiae sp.n., Austrognatharia homunculus sp.n., and Austrognatharia pecten sp.n.

Published: July 2005

The taxon Lycodrilusphreodriloides Michaelsen, 1905 is fully described for the first time. It is now recognized as Baikalodrilus phreodriloides (Michaelsen) comb.n., a member of the Tubificidae. This is the last of the original Lycodrilus species to be reclassified.
Phylogeny and classification of the Phyllodocidae (Polychaeta)
Authors: PLEIJEL FREDRIK
Published: July 2005

The phylogenetic relationships of the benthic phyllodocid genera are estimated by a parsimony analysis based on 26 morphological characters. It is concluded that the cephalization within Eteone has led to a reduction of segment 1 and loss of the first pair of tentacular cirri. Biramous parapodia (like in Austrophyllum and Notophyllum) constitute an ancestral state, which has evolved independently also within Phyllodoce. A new subfamily, Notophyllinae, is erected, and the two additional subfamilies, Phyllodocinae and Eteoninae, are redefined. Pareteoninae is treated as a junior synonym to Phyllodocinae, and Lugiinae as a nomen dubium. A number of genera are redefined and new combinations introduced. Based on type material Zverlinum and Phyllouschakovius are synonymized with Phyllodoce, Nipponophyllum with Notophyllym, Vitiaziphyllum with Eumida, Pareteone, Eulalia (Euphylla) and Compsanaitis with Paranaitis. More tentatively proposed synonymizations include Bergstroemia with Austrophyllum, Prophyllodoce with Phyllodoce, and Pseudeulalia with Protomystides. Eulalia lapsus is proposed as a replacement name for E. anoculata Fauchald, 1972, junior homonym to E. anoculata Hartman & Fauchald, 1971, and a number of species are synonymized and new combinations introduced. A checklist of phyllodocids together with information on the location of their type specimens is included.
Printed in Great Britain Setal type and distribution in two Australian species of Scyphoproctus (Polychaeta, Capitellidae) and three other capitellids, with a description of Scyphoproctus towraiensis sp.n.
Authors: DOYLE SUE
Published: July 2005

Scyphoproctus somalus (Polychaeta, Capitellidae) was discovered on sandbars on the north eastern side of Heron Island, Queensland. Scyphoproctus towraiensis sp.n. with similar morphological characters to S. somalus had been collected from Towra Point, Botany Bay, New South Wales. Fresh samples of both species were investigated using a number of techniques which have not been commonly used in capitellid taxonomy. Scanning electron microscopy was employed to examine the hood ornamentation of the abdominal hooded hooks, with a view to mapping the distribution of the various patterns seen along the length of the body. Several other genera were also examined for variations in setal morphology. Statistical studies of the setae showed that the setal characters tested were directly related to the size of the animal, but did not contribute to the separation of the two species. Allozyme electrophoresis differentiated between the two species of Scyphoproctus for a number of enzymes.
Printed in Great Britain Mandobius regalis gen. et sp.n. (Copepoda: Poecilostomatoida: Lichomolgidae) associated with the coral Pectinia lactuca in New Caledonia
Authors: HUMES ARTHUR G.
Published: July 2005

A new genus, Mandobius gen.n, containing a new species, M. regalis sp.n., is associated with the coral Pectinia lactuca in New Caledonia. The new copepod differs conspicuously from the allied genus Paramolgus in having only one seta on the first segment of the first antenna, in the formula 1,11,3 for the third segment of the endopodite of leg 1, and in the formula 11,1,5 for the third segment of the exopodite of leg 4.
ln situ observations on the genus Bathyplotes (Holothuroidea, Echinodermata) in Antarctica and its relevance to taxonomy
Authors: GUTT JULIAN , KLAGES MICHAEL
Published: July 2005

Nineteen holothurian specimens were photographed or videotaped in situ on the deeper shelf of the Weddell Sea (Antarctica). These specimens show a different gradient and combinations of characteristics which are found in Bathyplotes rubipunctatus Gutt, 1990. A close relationship to this species is therefore suggested. However, based on external features which are conspicuous in live animals but not visible in preserved material they are classified into five groups. Further investigations will reveal whether these groups are distinct species, or merely variants of B. rubipunctatus.
Hydra braueri Bedot 1912 (Cnidaria: Hydrozoa): investigations into the taxonomic status of an enigmatic species
Authors: CAMPBELL RICHARD D. , HOLSTEIN THOMAS W.
Published: July 2005

Hydra braueri Bedot, 1912, described 100 years ago by August Brauer, has influenced the development of hydra taxonomy but it has been observed rarely and its characters are puzzling. Hydra braueri has some characters normally associated with H. circumcincta Schulze, 1914 and others associated with H. oligactis Pallas, 1766. We show that the original description of H. braueri was derived from a mixture of these two species. This conclusion is based on an analysis of the original descriptions, on the succeeding literature on the animal, on examination of some of the early specimens still preserved in museums, and from study of other species of European hydra. Thus, H. braueri is a junior synonym of H. circumcincta, but some of the characters associated with the name H. braueri represent H. oligactis.

Geographic variation in Leporinus friderici (Bloch) (Pisces: Ostariophysi: Anostomidae) from the Paraná‐Paraguay and Amazon River basins
Authors: GARAVELLO JULIO C. , DOS REIS SÉRGIO F. , STRAUSS RICHARD E.
Published: July 2005

Morphological variation among populations of Leporinus friderici (Bloch), an anostomid fish of widespread neotropical distribution, has been hypothesized but never conclusively demonstrated. We used multivariate procedures to examine patterns of morphometric variation among populations of L. friderici from three South American biogeographic regions: the Paraná‐Paraguay River and Amazon River basins of Brazil, and the Marowijne River basin of Suriname. Samples from the southern Paraná‐Paraguay basin are completely distinct from the northern Amazonian and Suriname regions in principal components analysis, primarily on the basis of body elongation and orbit differcnces. Samples from the two northern regions were separated in a size‐free canonical variates analysis by differences in relative body depth. These results emphasize a need for further studies of neotropical fish species with similar distribution patterns.
Cranial phenotypic evolution in Proechimys iheringi Thomas (Rodentia: Echimyidae)
Authors: REIS S. F. DOS , PESSÔA L. M. , BORDIN B.
Published: July 2005

Models of evolutionary quantitative genetics were employed to analyze cranial phenotypic evolution in the echimyid rodent Proechimys iheringi Thomas. The hypothesis that cranial differentiation among populations and subspecies of P. iheringi resulted from random drift was rejected. The completely selective model was then used to reconstruct the forces of selection that might have acted to produce the observed differences in cranial morphometric traits in P. iheringi. The net gradient of selection indicates that some cranial traits evolved in the direction contrary to the forces of selection, acting to increase mean values for cranial traits in the evolutionary transitions between populations of P. iheringi. Minimum intensities of selection were calculated and showed that selective mortality per generation was low, of the order of l0‐3, suggesting that weak selection can explain the observed cranial morphometric differences among the populations of P. iheringi.
Redescription of Tethya norvegica Bowerbank (Porifera, Demospongiae), with remarks on the genus Tethya in the North East Atlantic
Authors: SARÀ MICHELE , BAVESTRELLO GIORGIO , MENSI PAOLA
Published: July 2005

Tethya norvegica Bowerbank, 1872, a northern species generally synonymized with T. aurantium. has been studied from Scotland, The Faroes, Norway, Iceland, Spitzbergen and Bear Island. The species is redescribed and its North East Atlantic distribution delimited Tethya norvegica is compared, on the basis of morphometric and electrophoretic features, with T. aurantium and F.citrina. Morphological, morphometric and electrophoretic data suggest that I norvegica is a distinct biological species.
Sperm morphology in the Pterastericolidae (Platyhelminthes, Rhabdocoela): phylogenetic implications
Authors: JONDELIUS ULF
Published: July 2005

The sperm morphology of five species of the Pterastericolidae was studied with transmission electron microscopy. The spermatozoa of all species have two axoncmes, which are incorporated in the sperm cell body for most of their length. The axonemes arc of the‘9 + 1’pattern characteristic of the flatworm taxon Trepaxonemata. Outer dynein arms are absent from the microtubule doublets in the axonemes. Dense bodies are few, and occur only in the distal part of the spermatozoa, but small electron dense granules are numerous. A sister group of the Neodermata consisting of the Pterastericolidae and the Fecampidae is proposed. The monophyly of the taxon Dalyellioida is discussed
Ultrastructure of spermiogenesis, spermatozoa and the tegument in Atriaster sp. (Platyhelminthes, Monogenea, Polyopisthocotylea, Microcotylidae)
Authors: JUSTINE JEAN‐LOU
Published: July 2005

Atriaster (Atriaster) sp., a gill parasite in the fish Diplodus cervinus caught near Dakar, Senegal, was studied by transmission electron microscopy. Spermiogenesis is similar to the general scheme in the Cercomeridae and particularly the polyopisthocotylean monogeneans, but shows two remarkable characteristics: (a) the zone of differentiation for each spermatid is separated from the common spermatid cytoplasmic mass by a region without longitudinal microtubules but with many mitochondria, herein termed the pre‐zone of differentiation; (b) transverse sections of nuclei in late spermatids are polygonal with concave sides. These two characteristics are provisionally interpreted as autapomorphies, since observations in other species are lacking. The outer layer of the tegument is similar to that of other polyopisthocotylean monogeneans, and has microvilli and three kinds of cytoplasmic inclusions: granules with fibrous contents, granules with homogeneous contents, and elongate electron‐dense bodies.
Differentiation of large arionid slugs (Mollusca, Pulmonata) using ligula morphology
Authors: NOBLE LESLIE R.
Published: July 2005

A study of the ligula (a holdfast/stimulatory device associated with the distal genitalia) in the species aggregatesArion aterandA. lusitanicus,common in NW Europe, suggests that examination of this organ may permit rapid and reliable differentiation to the sub‐specific level. This study describes the ligula and its taxon‐specific characteristics, illustrated by three‐dimensional stereo photographs, which clearly reveal its structure and can be readily compared with dissected material. The bizarre and intricate variations some taxa exhibit in the form of this organ are interpreted in terms of mating behaviour.
Ultrastructural investigations of three taxonomic characters in the trunk region of Echinoderes capitatus (Kinorhyncha, Cyclorhagida)
Authors: NEBELSICK MONIKA
Published: July 2005

The classification of Kinorhyncha is mainly based upon cuticular differentiations including closing apparatus, trunk cuticle, and various appendages. This paper investigates whether ultrastructural characters support taxonomic results based upon light microscopical characters. The trunk region of Eckinoderes cupitatus bears several epidermal glands and setae and one middorsal spine on the 6th zonite. These characters are constant in number and distribution. The epidermal glands are unicellular, merocrine, glandular cells with an opening built up by several ramified canals terminating in pores within a slightly elevated ring‐like bulge. Setae are composed of two cells, one merocrine glandular cell and one sensory cell with microvilli surrounding the outlet differentiation of the glandular cell. The setae have a pore on its tip, where the secretory product is released. The middorsal spine bears a multiciliar sensory cell. No pore is developed on the tip of the spine.

Authors: J.QUICKE DONALD L. , INGRAM SIMON N. , BAILLIE HELEN S. , GAITENS PAULINE V.
Published: July 2005

A light and electron microscopical survey of spermatozoan gross morphology and ultrastructure in the Hymenoptera is presented. Details are provided for the first time for members of the families Xyelidae, Argidae, Tenthredinidae, Diprionidae, Cephidae, Figitidae, Proctotrupidae, Diaprii‐ dae, Heloridae, Eurytomidae, Leucospidae, Perilampidae, Torymidae, Braconidae, Dryinidae, Sphecidae, Pompilidae and Vespidae. Spermatozoan length ranged from 8 μm in some Braconidae to 500 μm in one chalcidoid. Considerable variation in gross morphology and ultrastructure were observed between taxa. Several phylogenetically informative characters were noted. Very small spermatozoa characterized most of the non‐cyclostome subfamilies of Braconidae; spirally twisted axoneme and mitochondrial derivatives occur in the Eulophidae, Eurytomidae and Pteromalidae; spermatozoa with virtually indistinguishable head (nucleus and acrosome) regions characterized the Vespinae and Polistinae. The presence of well‐developed spermatodesmata in the vas deferens and seminal vesicle characterize the Symphyta and were largely absent from other groups though they are occasionally present in some bees.

Morphological and ecological characterization of Hercostomus (Hercostomus) plagiatus and a sibling species, H. verbekei sp.n. (Diptera: Dolichopodidae)
Authors: POLLET MARC
Published: July 2005

Although two forms of Hercostomus plagiatus are separated in identification keys, both were considered to belong to one single species. My investigations, however, revealed that two distinct species were included. In this respect, H. plagiatus is redescribed, whereas H. verbekei sp.n. is described as new. Both species occur mainly in central and southern Europe; H. plagiatus is more common than its congener at nearly all sites investigated. Aspects of macro‐ and microhabitat preference, phenology and sex ratios in H. plagiatus are discussed. It is suggested that these two species are closely related.
Ancora prolifera sp.n., a gregarine parasite of Microphthalmus ephippiophorus Clausen (Polychaeta, Hesionidae)
Authors: CLAUSEN CLAUS
Published: July 2005

Ancora prolifera sp.n. (Gregarinasina) is described from the interstitial polychaete Microphthalmus ephippiophorus Clausen, 1986. The parasite was studied in the live host by phase and interference contrast optics and as wholemounts of host and isolated trophozoites. The trophozoite has a broadened anterior portion with a pair of unequal lateral processes, a long, triangle‐shaped posterior portion, and numerous longitudinal pellicular striations. It is characterized by exogenous budding. Gametogony has not been observed, but zoites were seen to develop into the characteristic trophozoite. The role of the budding is briefly discussed.

Adaptive, taxonomic, and phylogenetic aspects of female abdominal features in Oligotrophini (Diptera, Cecidomyiidae), and four new Dasineura species from the Western Palearctic
Authors: SYLVÉN EDVARD , TASTÁS‐DUQUE RUBEN
Published: July 2005

The external structure of the end part of the female abdomen in Oligotrophini was studied. Various patterns were found, some of them representing adaptations of limited value for phylogenetic considerations, but the analysis also demonstrated synapomorphies for certain genera. For example, all known species of Gephyraulus are equipped with a pair of horn‐like sensilla situated dorsally near the tip of the superior lamella. This development apparently does not occur in other Oligotrophini. Six general models regarding the cuticular sculpture of the superior lamella were distinguished in Dasineura and Macrolabis. Evolution of some of the models may have occurred several times. Lectotypes of Jaapiella catariae Rübsaamen and Wachtliella dalmaticu Rübsaamen are designated. Wachtliella rosarum (Hardy) is transferred to Dasineura. Four new species are described: Dasineura mariae sp. n., D. berti sp. n., D. helenae sp. n., and D. erodiicola sp. n.
Phylogenetic position of rhyacophiloid caddisflies (Insecta, Trichoptera): a spermatological analysis of Rhyacophilidae and Glossosomatidae
Authors: FRIEDLÄNDER MICHAEL
Published: July 2005

Most caddisflies (Insecta, Trichoptera) are classified into two suborders, Annulipalpia and Integripalpia. However, the use of the derived characters that are regularly applied in systematic and phylogenetic analyses of Trichoptera is insufficient to determine with certainty the position of the families belonging to Rhyacophiloidea, which are considered by different authors to be either Annulipalpia, or Integripalpia, or even a separate suborder. Rhyacophiloidea comprise four overall similar families: free‐living Rhyacophilidae and Hydrobiosidae, saddle‐case making Glossosomatidae, and purse‐case making Hydroptilidae. It was previously found that Annulipalpia spermatozoa have aberrant axonemes while Integripalpia spermatozoa display the plesiomorph 9 + 2 axoneme. The present spermatological analysis of the families Rhyacophilidae and Glossosomatidae shows that both have spermatozoa with aberrant axonemes lacking the two central microtubules found in the typical axoneme of insect spermatozoa. This is an apomorphic character shared with the superfamily Hydropsychoidea, indicating that from this point of view, Rhyacophiloidae are more closely related to Annulipalpia than to Integripalpia.
