A chromosomal investigation of five European species of Anacaena Thomson (Coleoptera: Hydrophilidae)
Authors: Shaarawi Fatma A. , Angus Robert B. 
Published: July 2010

AbstractChromosomal data are given for five European species of Anacaena. A. bipustulata, A. limbata and A. lutescens have the diploid number 16 + XY (male), 16 + XX (female). A. globulus has the number 14 + XY/XX, while in A. rufipes the number is 10 + neo-XY (male). Chromosomal data from various Hydrobiinae suggest that a diploid number of 16 + XY or XX is normal in this subfamily, and that the karyotypes of A. globulus and A. rufipes result from reductions in number. In A. globulus the sizes and shapes of the chromosomes suggest that there may have been loss of the centromere from one of the smaller chromosome pairs, with the two arms fusing with two different autosomes. In A. rufipes the process appears to have gone further, with the original sex chromosomes fusing with a pair of autosomes to give a neo-XY. The karyotypes of all five species are distinctive, confirming the recognition of A. lutescens as a distinct species. In populations of A. lutescens comprising only females, all specimens were heterozygous for a deletion polymorphism in one pair of autosomes. This deletion was not found in bisexual populations. Two of the females-only populations included a proportion of triploid individuals, and this, in conjunction with the deletion polymorphism, is taken as evidence that these populations are parthenogenetic. Present evidence is not considered sufficient to show whether the parthenogenesis has a single origin in A. lutescens or whether it is polyphyletic, though the discovery of consistent small differences in the relative length of two autosomes, between parthenogenetic and bisexual populations, suggests a single origin. The triploid karyotypes show small differences between the two populations in which they are known, and this suggests that triploidy has arisen after the establishment of parthenogenesis, and is of multiple origins. In most cases the only tissue available for chromosome preparations was mid-gut of adult beetles, and the methods used are described.
Tibiotarsal chaetotaxy in Tullbergiinae (Collembola: Onychiuridae)
Authors: Fjellberg Arne 
Published: July 2010

AbstractSix types of tibiotarsal chaetotaxy are recognised among genera of the subfamily Tullbergiinae. The most complete chaetotaxy is found in the nearctic species Thllbergia clavata Mills, while the most reduced type is displayed by many species of Mesaphorura and related genera.
A new species of Bryophaenocladius Thienemann (Diptera: Chironomidae) from Norway, with emendations to the diagnoses of the genus
Authors: Schnell Øyvind A. 
Published: July 2010

AbstractAll life stages and both sexes of Bryophaenocladius faegrii sp. n. are described. The pupa especially has characters not previously found in the genus, including a thoracic horn and several pairs of setae on the cephalic sheath and on tergite IX. Also the male, female and larva exhibit characters in new combinations. Corrected and emended generic diagnoses for the different life stages are given, and aspects of the ecology of the species are discussed.
The larvae of Placusa Mannerheim (Coleoptera: Staphylinidae), with notes on their feeding habits
Authors: Ashe James S. 
Published: July 2010

AbstractLarvae of Placusa despecta Erichson collected in association with adults were described in detail and compared with reared larvae of Placusa tachyporoides Waltl. Illustrations of structural features and chaetotaxy are provided. These larvae are very similar to those of Euvira Sharp. These similarities are outlined and a table of features which will distinguish between larvae of these two genera is provided. Gut contents of both larvae and adults were composed of large masses of hyphae, asexual fruiting structures and similar parts of imperfect fungi. This, as well as structural evidence, strongly supports the conclusion that both adults and larvae of Placusa are primarily fungivores in the subcortical habitat.
Electrophoretic and morphometric analyses of two sibling species pairs in Trachyphloeus (Coleoptera: Curculionidae)
Authors: Simonsen V. , Loeschcke V. , Mahler V. , Jermn L.S. 
Published: July 2010

AbstractMisidentified specimens of Trachyphloeus bifoveolatus (Beck, 1817), T. angustisetulus Hansen, 1915, T. spinimanus Germar, 1824 and T. digitalis (Gyllenhal, 1827) are very frequent in weevil collections and reflect the ambiguous taxonomic status of some of these taxa. The taxonomic problems are a result of (1) sole use of traditional morphological differences, (2) the weevils' assumed parthenogenetic reproduction which prevents the use of Mayr's species concept, and (3) lack of information about their biology and genetics. Our present electrophoretic, morphometric and morphological analyses of live and dry-mounted samples of females from north and west Europe indicate that the four taxa are each genetically and morphologically distinct species. New keys which permit easy and reliable identification of the species are provided.
Praecoris dominicana gen. n., sp. n. (Hemiptera: Reduviidae: Holoptilinae) from Dominican amber, with an interpretation of past behavior based on functional morphology
Authors: Poinar George O. 
Published: July 2010

AbstractAn ant bug of the subfamily Holoptilinae (Reduviidae: Hemiptera), Praecoris dominicana gen. n., sp. n., is described in amber from the Dominican Republic. Based on the functional morphology of extant forms, the behavior of the fossil bug as an ant predator is discussed. This find clearly establishes the Holoptilinae in the New World during the Tertiary and gives credence to the single New World extant specimen reported from Guyana. It is likely that the prey of the fossil specimen was the arboreal ant, Dolichoderus dibolia. Both the bug and its ant prey are now extinct and no descendents occur in the Greater Antilles today.
Review of the genus Styletta (Diptera: Phoridae), with description of a new genus
Authors: Gibson R.L. , Francoeur A. , Brown B.V. 
Published: July 2010

AbstractSpecimens of a Nearctic phorid fly, tentatively placed in the genus Styletta Borgmeier, are found to be more closely related to the genus Menozziola Schmitz. A new genus, Trucidophora Brown, is proposed for the Nearctic Region species previously described as Styletta camponoti Brown. The correct name for this taxon is now T. camponoti (Brown) (new combination). Similarly, S. ewardurskae Disney (from Europe) is transferred to Trucidophora (new combination). Third instar larva, puparium and life history information are described for T. camponoti, which is a parasitoid of alate females of Camponotus herculeanus (L.), C. novaeboracensis (Fitch) and C. pennsylvanicus (De Geer) (Hymenoptera: Formicidae). We suggest that parasitism of alate female ants, which is also recorded for M. schmitzi (Menozzi) from Europe, is a further synapotypy of Menozziola and Trucidophora. Multiple parasitism may also be a synapotypy of these two genera, but too little data on other phorid life histories are available to polarize this character state correctly. The male of the Neotropical Region phorid Styletta crocea Borgmeier, the type species for that genus, is described for the first time, and the structure of the male and female terminalia are illustrated. New distribution records are given for T. camponoti, S. crocea, and North American Menozziola sp. Modifications are suggested for the Manual of Nearctic Diptera key to Phoridae to allow identification of the Nearctic Region taxa.
A new genus of marine water striders (Hemiptera, Veliidae) with five new species from Malesia
Authors: Møller Andersen N. 
Published: July 2010

AbstractThe generic classification of water striders belonging to the veliid subfamily Haloveliinae is discussed and revised and a key to the genera provided. A new genus of marine haloveliines, Haloveloides gen. n., is described. The type species of the new genus, H. papuensis (Esaki) comb. n., is redescribed and recorded from Papua New Guinea, the Bismarck Archipelago, and the Solomons. H. browni (Lansbury) comb. n. is redescribed and recorded from the same areas as the type species. Five new species are described in the genus: H. brevicornis sp. n. (the Moluccas, Sulawesi, Palawan), sundaensis sp. n. (Sunda shelf areas), danpolhemi sp. n. (Palawan), cornuta sp. n. (Luzon), and femoralis sp. n. (Palawan). The cladistic relationships and biogeography of the species are discussed.
On Tunagyna and Thaleria, two closely related Siberio-Nearctic spider genera (Araneida: Linyphiidae)
Authors: Marusik Yu M. , Eskov K. Yu. 
Published: July 2010

AbstractThe erigonine genera of obscure taxonomic affinities, Tunagyna and Thaleria, are considered as closest relatives. Tunagyna is regarded as monobasic, due to reassignment of T. antricola to Phanetta (comb. n.). Four Siberian new species (T. alnetorum sp.n., T. evenkiensis sp.n., T. sajanensis sp.n., T. sukatchevae sp.n.), as well as one Alaskan (T. leechi sp.n.), have been added to the formerly monobasic Thaleria.
Systematics of the genus Colocasiomyia de Meijere (Diptera: Drosophilidae): cladistics, a new generic synonym, new records, and a new species from Nepal
Authors: Grimaldi David 
Published: July 2010

AbstractThe fly species crassipes de Meijere is transferred from the Sphaeroceridae to the Drosophilidae since Platyborborus de Meijere, a monotypic genus, is a junior synonym of Colocasiomyia de Meijere. Colocasiomyia crassipes is a very highly modified member of the genus due to its flattened body, reduction and loss of many groundplan setae, deep antennal fossae, and crassate hind legs. The holotype and only known specimen, from Java, is redescribed in detail and illustrated. New records of Colocasiomyia stamenicola (Carson & Okada) and C. gigantea (Okada) are reported from Guadalcanal, Solomon Islands, considerably outside their reported ranges. Colocasiomyia nepalensis sp. n. is described from Kathmandu, Nepal. Cladistic relationships in the genus are briefly examined and related to biogeography and aroid host use.
A new key to some genera of Ceratopogonini in the Holarctic (Diptera: Ceratopogonidae)
Authors: Borkent Art 
Published: July 2010

AbstractThe most recent key identifying Nearctic genera of Ceratopogonidae by Downes & Wirth (1981) is improved with modifications and additional characters for distinguishing the genera Alluaudomyia, Brachypogon, Ceratoculicoides, Ceratopogon, Nannohelea and Rhynchohelea. Suggestions are also provided for improvements to the world key to Ceratopogonini by Wirth & Grogan (1988).
The cockroach genera Sigmella Hebard and Scalida Hebard (Dictyoptera: Blattaria: Blattellidae)
Authors: Roth Louis M. 
Published: July 2010

AbstractDiagnostic characters are given for distinguishing between Scalida Hebard and Sigmella Hebard, two genera which have been considered synonyms. Most of the species discussed are redescribed, two new species of Sigmella are described, and a key is presented to separate the males of 13 species in this genus.
Review of first-instar larvae of Colymbetini (Coleoptera: Dytiscidae), with a key to genera and phylogenetic analysis
Authors: Nilsson Anders N. , Hilsenhoff William L. 
Published: July 2010

AbstractThe first-instar larva of Meladema coriacea Laporte, 1835 is redescribed, and that of Neostutopterus hornii (Crotch, 1873) is described for the first time. A generic key to first-instar larvae of Colymbetini is presented, but it does not include the monobasic New World genera Bunites Spangler and Hoperius Fall, whose young larvae are unknown. Polarity is determined for a set of 12 characters of first-instar larvae, and the distribution of character states among genera is used to reconstruct phylogeny. It suggests that Meladema Laporte and Neoscutopterus J. Balfour-Browne together form the most derived lineage of the Colymbetini, whereas Colymbetes Clairville is the least derived genus.
Tentative reconstruction of the ditrysian phylogeny (Lepidoptera: Glossata)
Authors: Minet Joel 
Published: July 2010

AbstractThe Ditrysia, which comprise the great majority of extant Lepidoptera, are divided into thirty superfamilies (instead of the fifteen to twenty usually recognized). Several of them are conceived in a new sense and one is newly proposed: the Choreutoidea. The Dudgeoneidae are reassigned to the Cossoidea, the Sematuridae and Uraniidae to the Geometroidea, while the Anthelidae and Lasiocampidae are placed in the Lasiocampoidea, a superfamily differing from the Bombycoidea mainly in retaining unfused prothoracic coxae in the larva. The Alucitoidea comprise the Tineodidae, Oxychirotidae and Alucitidae, and the Drepanoidea the Epicopeiidae and Drepanidae. Sister group relationships are recognized between the following superfamilies: Yponomeutoidea / Gelechioidea, Cossoidea / Sesioidea, Alucitoidea / Pterophoroidea, Hesperioidea / Papilionoidea and Drepanoidea / Geometroidea. Reliable monophyletic groups are the Mimallonoidea + Lasiocampoidea + Bombycoidea and the Hedyloidea + Rhopalocera. A few clades are suggested at a higher level, e.g. the Apoditrysia, the Obtectomera (based on two autapomorphies: pupa with fixed abdominal segments 1-4, and imago with modified pulvilli) and the Macrolepidoptera (mainly based on the shape of the first axillary sclerite in the forewing base). Several other changes are introduced: the ' Pseudocossinae' are restricted to the Madagascan genus Pseudocossus Kenrick (possibly belonging in the Brachodidae); the Macropiratinae (stat. n.) are regarded as the most primitive Pterophoridae; the Charideinae are transferred from the Zygaenidae to the Thyrididae; within the Thyrididae, the Argyrotypinae are regarded identical with the Siculodinae (syn. n.). Finally, two families are newly proposed within the Apoditrysia: the Simaethistidae (fam. n.) and Whalleyanidae (fam. n.). The superfamily relationships of these two families have not been determined.
The Ceratopogonidae (Diptera) of the Galápagos Islands, Ecuador with a discussion of their phylogenetic relationships and zoogeographic origins
Authors: Borkent Art 
Published: July 2010

AbstractEleven species of Ceratopogonidae are recognized on the Galápagos Islands. Four of these appear to be endemic, six are widespread occurring elsewhere on the continental Americas and one is of uncertain distributional status. One of the endemic species is described as new, Dasyhelea sinclairi Borkent. Each of the species is most closely related to taxa occurring elsewhere than on the Galápagos Islands (with one possible but unlikely exception of two of these being sister species), indicating at least ten independent invasions of the islands by the ancestors or ancestral populations of these species. It is uncertain whether the widespread species have been brought through the agency of man or through natural dispersal to the Galápagos Islands. Based on comparisons with the Ceratopogonidae fauna of oceanic islands elsewhere, the presence of endemic species only in the genera Forcipomyia and Dasyhelea on the Galápagos Islands is likely due to the superior dispersal capabilities of members of these genera. This may also explain the presence of those ceratopogonid species occurring both on the Galápagos Islands and the New World mainland.
The lithobiomorph centipedes of the Canary Islands (Chilopoda)
Authors: Enghoff H. , Eason E.H. 
Published: July 2010

AbstractEleven species of Lithobius and three of Lamyctes are recorded from the Canary Islands, Lithobius comsimilis Eason, sp. n., L. canariensis Eason, sp. n. and Lamyctes mauriesi Demange, 1981, for the first time. These three species are described. Several species are recorded as new for one or more island. A key is provided for the identification of all the species recorded.
Taxonomy of Saldula: revised genus and species group definitions, and a new species of the pallipes group from Tunisia (Heteroptera: Saldidae)
Authors: Polhemus John T. , Lindskog Per 
Published: July 2010

AbstractA revised diagnosis of the genus Saldula Van Duzee based upon synapomorphic characters of male genitalia and hemelytral pigmentation patterns is given. According to this concept ca. 55% of the species World-wide currently assigned to Saldula will have to be transferred to other genera. Several new characters are employed in the definition of species and species groups. The species attributable to the pallipes species group are listed and supplemented by a brief overview of the taxonomic relationships of the Old World species. Saldula luteola sp. n. is described from coastal salt marshes on the Island of Djerba, Tunisia. It mainly appears in extremely depigmented morphs unparalleled elsewhere in the Saldidae and likely constitutes a sister-species of S. sardoa Filippi. The conspicuous intraspecific variation in body size and hemelytral pigmentation in S. palustris (Douglas), the closest relative of the former species, is depicted and briefly discussed. The descriptive accounts are accompanied by numerous photographic illustrations of somatic and genital characters.
Sex chromosome systems of European noterid beetles (Coleoptera, Adephaga: Noteridae)
Authors: Bilton D.T. 
Published: July 2010

AbstractThe karyotypes and sex chromosome systems of the four European species of noterid beetles are described. Chromosome preparations were made from the mid-gut and testes of adult beetles by acetic acid spreading. Canthydrus diophthalmus was found to have a chromosome compliment of 2n = 16 + XX/XY. A multiple sex chromosome system was common to the three species of Noterus investigated (2n = 18 + X1X1X2X2/X1X2Y). The behaviour of Noterus sex chromosomes during early meiosis was examined and is discussed, along with the occurrence of multiple sex chromosome systems in other Adephaga.
Revision of the cluster-flies of the Pollenia venturii species-group, with a cladistic analysis of Palaearctic species of Pollenia Robineau-Desvoidy (Diptera: Calliphoridae)
Authors: Rognes Knut 
Published: July 2010

AbstractWithin Pollenia Robineau-Desvoidy a venturii species-group is defined and revised. It consists of a single species P. venturii Zumpt. P. solitaria Grunin is proposed as a junior synonym. It is characterized by unique features in the male aedeagus and the lateral sacs of the internal female reproductive organs. Male and female terminalia are illustrated, the latter for the first time. A preliminary cladistic analysis of all known Palaearctic species of Pollenia (except P. japonica Kano & Shinonaga) suggests that the sister-group of P. venturii is a clade consisting of the viatica + vagabunda + amentaria + haeretica species-groups. A sclerotized internal wall of the lateral sacs in the internal reproductive system of female Pollenia appears to be a parallelism developed independently in the venturii, rudis, most members of the tenuiforceps and some members of the semicinerea groups, rather than an underlying synapomorphy. P. venturii is known from France, Germany, Greece, Italy and Russia. A key is provided to species-groups in Pollenia.
Oriental nirvanine leafhoppers (Homoptera: Cicadellidae): a review of C. F. Baker's species and keys to the genera and species from Singapore, Borneo and the Philippines
Authors: Viraktamath C.A. 
Published: July 2010

AbstractThe type series of 18 out of 19 species of Nirvaninae described by C. F. Baker in nine genera were examined and lectotypes designated. Jassonirvana lineata Baker and Stenometopius mindanaoensis Baker are removed from the Nirvaninae as they belong to Deltocephalinae. Each of the remaining species and Kana maculata Baker (based on specimen collected from the type locality) are redescribed with respect to the male and female genitalia wherever available and are illustrated. Keys to included genera and species are also provided. Pseudonirvana Baker is treated as a junior synonym of Sophonia Walker. New combinations proposed are Sophonia marginata (Baker) (from Ophiuchus), Pactana picea (Baker) (from Kana), Nirvana sanguinolineata (Baker) and Nirvana davaoensis (Baker) (both from Pseudonirvana). The latter species is treated as a junior synonym of Nirvana philippinensis Baker. The genera Nirvanoides Baker, Pythonirvana Baker and Pactana Linnavuori are redescribed.
A reciassification of the Deronectes-group of genera (Coleoptera: Dytiscidae) based on a phylogenetic study
Authors: Nilsson Anders N. , Angus Robert B. 
Published: July 2010

AbstractWithin the Hydroporini, the Deronectes-group of genera are characterised by having the mesosternal fork and metasternal keel separated (or secondarily fused), the ventral elytral ridge posteriorly elevated but without ligula, and the male protarsus ventrally without adhesive discs. The genera of the group, viz. Deronectes Sharp, 1882, Stictotarsus Zimmermann, 1919, Scarodytes Gozis, 1914, and Nebrioporus Regimbart, 1906, are reclassified and a hypothesis of their phylogenetic relationships is presented. Karyotypes of 14 European species of Hydroporinae are discussed. Nebrioporus is extended to include most species with parameres with apex hook-like and sclerotised, with Potamonectes Zimmermann, 1921, as a junior synonym, syn. n. Nebrioporus s. str. and Zimmermannius Guignot, 1941 are recognized as subgenera of Nebrioporus. Scarodytes is kept as a separate genus because of its characteristic ventral sculpture and seemingly higher number of autosomes than in Nebrioporus. The species with simple parameres previously placed in Potamonectes are transferred to Stictotarsus together with S. bertrandi (Legros, 1956), previously in Deronectes. Consequently, Trichonectes Guignot, 1941, is a junior subjective synonym of Stictotarsus, syn.n. In an appendix, a check-list is provided for the species of the Deronectes-group. The subgenus Nebrioporus s. str. is divided into three species-groups: the kilimandjarensis-, the abyssinicus-, and the depressus-groups.
Revision of the baetica-group of Phyllodromica in Spain (Blattaria: Blattellidae: Ectobiinae)
Authors: Bohn Horst 
Published: July 2010

AbstractThe baetica-group forms a very characteristic group of Phyllodromica species only occurring in the Southern Cordilleras of Spain. In addition to the three species already known (P. baetica (Bolivar), P. princisi Fernandes, P. agenjoi Harz) six new species and a new subspecies are described (P. erythrura, P. intermedia, P. krausei, P. maculosa, P. paludicola, P. striolata, P. princisi ssp. bermejae). The characteristics of the group are described and depicted, and a key for the identification of the species is given.
