Exploiting mimicry: Prosorhynchoides thomasi n. sp. (Digenea: Bucephalidae) from the fang blenny genus Plagiotremus (Bleeker) (Blenniidae) from off Lizard Island on the Great Barrier Reef, Australia
Authors: ROBERTS-THOMSON ASHLEY , BOTT NATHAN J.
Published: February 2019

Prosorhynchoides thomasi n. sp. (Digenea: Bucephalidae) is described from the intestine of the fang blennies, Plagiotremus tapeinosoma and P. rhinorhynchos (Blenniidae: Nemophini) from off Lizard Island, Great Barrier Reef, Australia.  The new species is differentiated from other species of Prosorhynchoides Dollfus, 1929 that also have testes which are symmetrical or nearly symmetrical by the shape and direction of the caecum and the position of the ovary relative to the caecum.  This is the first report of a new species, but the second report of adult bucephalids from Plagiotremus spp.  Prosorhynchoides thomasi n. sp. likely exploits the habit of Plagiotremus spp. of mimicking cleaner wrasse (Labridae) behaviour and micropredation on ‘client’ fish.  We have not encountered this species from other blennies or from other teleost families known to be infected with bucephalids from the Great Barrier Reef

Description of a new species of catshark, Atelomycterus marnkalha n. sp. (Carcharhiniformes: Scyliorhinidae) from north-east Australia
Authors: JACOBSEN IAN P. , BENNETT MIKE B.
Published: February 2019

A new atelomycterine catshark species (Scyliorhinidae: Atelomycterinae), Atelomycterus marnkalha n. sp., is described from north-east Australia (Great Barrier Reef Marine Park, Torres Strait and Gulf of Carpentaria). It differs from A. baliensis, A. marmoratus and A. macleayi in having posteroventally sloping dorsal fins, a lower precaudal vertebrae count and smaller adult size. Most similar to the Western Australian catshark species A. fasciatus, A. marnkalha differs from this species in having a larger anal fin, lateral denticles with prominent shallow depressions, claspers of adult males with a cover rhipidion lacking an obvious notch and its colour pattern with prominent white spots and fewer, smaller black spots.

A new species of Phymaturus from rocky outcrops in the central steppe of Rio Negro province, Patagonia Argentina (Reptilia: Iguania: Liolaemidae)
Authors: SCOLARO JOSÉ ALEJANDRO , IBARGÜENGOYTÍA NORA RUTH
Published: February 2019

A new Phymaturus species called Phymaturus ceii, in the honour of the late Professor José Miguel Cei, is described in the present study. The new species is a member of the “Phymaturus patagonicus” group from Patagonia. It lives at about 1200 m of altitude in a volcanic rocky habitat near to El Cuy plateau, in the central steppe of Rio Negro province, Argentina. The new species and the closely related P. patagonicus are morphologically compared, and its distribution and natural history are pointed out.
The non-Amazonian species of the Brazilian wandering spiders of the genus Phoneutria Perty, 1833 (Araneae: Ctenidae), with the description of a new species
Authors: MARTINS ROSANA , BERTANI ROGÉRIO
Published: February 2019

The five non-Amazonian species of the medically important spider genus Phoneutria Perty, 1833 are taxonomically reviewed, including the description of a new species, P. eickstedtae sp. nov. from Brazil. Phoneutria keyserlingi (F.O. Pickard-Cambridge, 1897) and P. pertyi (F.O. Pickard-Cambridge, 1897), currently listed as junior synonyms of P. nigriventer (Keyserling, 1891), are revalidated and a modern redescription of P. pertyi is presented. Phoneutria luederwaldti Mello-Leitão, 1927, also currently listed as junior synonym of P. nigriventer, is considered nomen dubium as the faded condition of the juvenile holotype does not allow an accurate species identification. The non-Amazonian Phoneutria are mainly restricted to Atlantic rainforest and forest fragments in the Cerrado in Brazil. Phoneutria nigriventer also occurs in northern Argentina and was introduced to Uruguay. A modified taxonomic key allows an identification of all eight Phoneutria species.Key-words: armed spider, banana-spider, taxonomy, Neotropical, Brazil
Coryphopterus kuna, a new goby (Perciformes: Gobiidae: Gobiinae) from the western Caribbean, with the identification of the late larval stage and an estimate of the pelagic larval duration
Authors: VICTOR BENJAMIN C.
Published: February 2019

A new goby, Coryphopterus kuna, is described from the Atlantic coasts of Panama and Mexico. The species is distinguished from other Coryphopterus spp. by the low median fin and pectoral fin ray counts and the morphology of the pelvic fin. The pelvic fins are fully joined with a rounded outline and have branched and longer innermost pelvic fin rays. There is no frenum connecting the two pelvic fin spines and the fin is heavily speckled with black spots in the male holotype. The late larval stage of C. kuna is identified by DNA sequence matching and is morphologically similar to other larval Coryphopterus spp. but has a distinct melanophore pattern. Examination of the otolith microstructure reveals a relatively long pelagic larval duration of 63 days with a narrowing of the later daily increments suggesting delayed metamorphosis. The species is the first vertebrate to include gene sequence barcoding under the Barcode of Life Data System (BOLD) in the species description.

Beckidia sp. is assigned to the genus Kloosia; Chernovskiia orbicus (Townes, 1945) is reconfirmed based on the larvae; Robackia sp. is allotted to R. pilicauda (Sæther, 1977), and the presumed larva described for the first time; and Saetheria sp. is allotted to S. tylus (Townes, 1945).
Redescription of Tipula octomaculata Savchenko, with notes on related Holarctic species (Diptera, Tipulidae)
Authors: SALMELA JUKKA , AUTIO OLLI
Published: February 2019

Tipula (Pterelachisus) octomaculata Savchenko, 1964 (Diptera, Tipulidae) has hitherto been known only from the type locality in north-western Russia, and no material besides the holotype male has been available for study. In this article we report T. octomaculata for the first time from Finland, redescribe the species and compare its morphological characters with those of related Nearctic species (T. trivittata Say, T. angulata Loew, T. entomophthorae Alexander). The Finnish finding locality in Ks: Taivalkoski, North boreal ecoregion, is briefly discussed.
First record of the genus Dinophasma Uvarov from the Philippines (Phasmatodea: Aschiphasmatidae)
Authors: GOTTARDO MARCO
Published: February 2019

As presently defined, the genus Dinophasma Uvarov, 1940 (= Dina Redtenbacher, 1906, = Xylobistus Zompro, 2004) includes 8 species (Otte & Brock, 2005), 7 of which are widespread in Borneo and one is represented in India. A study of several unidentified specimens of Philippine Aschiphasmatidae allowed recognition of a single male specimen of Dinophasma that cannot be assigned to any known species. The new species is described and illustrated in the present paper and marks the first record of the genus from the Philippines. An identification key to all species of Dinophasma, revised from that presented by Bragg (2001), is also provided

The tadpole of Hypsiboas latistriatus (Caramaschi & Cruz, 2004), a species of the Hypsiboas polytaenius (Cope, 1870) clade (Amphibia, Anura, Hylidae)
Authors: ORRICO VICTOR GOYANNES DILL , MONGIN MARCELLE MANTOANELLI , DE CARVALHO-E-SLIVA ANA MARIA PAULINO TELLES
Published: February 2019

Herein we describe the tadpole of Hypsiboas latistriatus from its type-locality and an adjacent, higher elevation pond. The tadpole is similar to the known tadpoles of other species of the H. pulchellus group. The tadpoles of H. latistriatus can be distinguished from other species group tadpoles by their oral formula [2(1,2)/ 3(1)] allied with a rounded lateral profile of the tail fins, instead of taper. The overall morphology is congruent with bentonic tadpoles. The tadpoles of H. latistriatus are usually found in Highland grass fields above 2000 m.a.s.l. in clear slow-flowing water bodies. Almost all tadpoles used in this study presented highly whitened mouthparts suggesting the presence of the fungal pathogen Batrachochytrium dendrobatidis.
Paraphyly of Chinese Amolops (Anura, Ranidae) and phylogenetic position of the rare Chinese frog, Amolops tormotus
Authors: CAI HONG-XIA , CHE JING , PANG JUN-FENG , ZHAO ER-MI , ZHANG YA-PING
Published: February 2019

In order to evaluate the five species groups of Chinese Amolops based on morphological characteristics, and to clarify the phylogenetic position of the concave-eared torrent frog Amolops tormotus, we investigated the phylogeny of Amolops by maximum parsimony, Bayesian Inference, and maximum likelihood methods using two mitochondrial DNA fragments (12S rRNA, 16S rRNA). Our results supported a sister group relationship of Amolops ricketti and Amolops hainanensis. However, the grouping of Amolops mantzorum and Amolops monticola needs to be resolved with more data. Amolops tormotus was nested in genus Odorrana. Thus, recognition of the A. tormotus group is unwarranted and A. tormotus should be referred to genus Odorrana as O. tormota. This species is the sister group of O. nasica plus O. versabilis. The new classification implies that the genus Wurana is to be considered as junior subjective synonym of Odorrana.
Fundulopanchax kamdemi (Cyprinodontiformes: Nothobranchiidae) a new species from Korup National Park, western Cameroon
Authors: AKUM CHRISTIAN , SONNENBERG RAINER , VAN DER ZEE JOUKE R. , WILDEKAMP RUDOLF H.
Published: February 2019

Fundulopanchax kamdemi, new species, is described from small swampy pools and rivulets of the Ndian and Akpa-Yafe River systems, Cameroon. F. kamdemi is distinguished from all other known Fundulopanchax species by a unique male coloration and from most congeners by a higher number of rays in dorsal and anal fins.
Get an eyeful of this: a new species of giant spitting cobra from eastern and north-eastern Africa (Squamata: Serpentes: Elapidae: Naja)
Authors: WÜSTER WOLFGANG , BROADLEY DONALD G.
Published: February 2019

We describe a new species of giant spitting cobra, Naja ashei sp. nov., from eastern and north-eastern Africa. The species was previously regarded as a colour phase of the black-necked spitting cobra, N. nigricollis. However, mtDNA sequence data show it to be more closely related to N. mossambica than N. nigricollis. The new species is diagnosable from all other African spitting cobras by the possession of a unique clade of mtDNA haplotypes and a combination of colour pattern and scalation characteristics. Its distribution includes the dry lowlands of northern and eastern Kenya, north-eastern Uganda, southern Ethiopia and southern Somalia.
A new species of the genus Diaphanes Motschulsky (Coleoptera: Lampyridae) from Gaoligong Mountains of Yunnan, Southwest China
Authors: LI XUEYAN , LIANG XINGCAI
Published: February 2019

A new species, Diaphanes pectinealis Li & Liang, from Gaoligong Mountains of Yunnan, Southwest China, is described. Individuals of this species are characterized mainly by the long and strongly pectinate antennae in males and the greatly developed and sclerotized incurved lobe along the dorsal inner margin of male parameres. The characters of the new species challenge the traditional generic diagnoses of Diaphanes and the limits between Diaphanes and its similar genus Pyrocoelia, and reinforce the necessity of a taxonomic revision on these two genera. The types are deposited in Kunming Institute of Zoology, Kunming, and Institute of Zoology, Beijing, the Chinese Academy of Sciences. A checklist of known Chinese Diaphanes species is provided.

Morphological variation and sexual dimorphism in the California skate, Raja inornata Jordan and Gilbert, 1881 from the Gulf of California, Mexico
Authors: GENIZ JOSÉ LEONARDO CASTILLO , NISHIZAKI OSCAR SOSA , JIMÉNEZ JUAN CARLOS PEREZ
Published: February 2019

Knowledge of taxonomy, systematics and life histories of the skates that inhabit the Gulf of California is scarce. Five species have been documented in the Sea of Cortez: R. cortezensis, R. equatorialis, Raja inornata, R. rhina and R. velezi. The California skate (R. inornata) is the most abundant species caught as by-catch during the hake trawl fishery in the Gulf. Intraspecific variation in the external morphology of R. inornata from the northern Gulf of California, México is described on the basis of 24 proportional morphometric variables from 45 males (227–525 mm total length TL) and 52 females (226-690 mm TL). Males and females had 9 and 14 proportional dimensions respectively that were isometric with total length (TL). Regression slope and elevation analysis revealed that 9 relationships between TL and morphometric variables were sexually dimorphic. A stepwise discriminant function separated three groups of skates (females and males of R. inornata and males of Raja cortezensis) and was able to correctly classify 97%, 100% and 100% of the original grouped cases, respectively. The variables that best discriminated between species and sexes were preorbital length, preoral length, distance between fifth gill openings, maximum distance between pelvic fins, and distance from cloaca to anterior caudal fin. The study also revealed that several of the meristic characters examined showed considerable variation and, therefore, should be used with caution in taxonomic studies.

Genitives of species and subspecies nomina derived from personal names should not be emended
Authors: DUBOIS ALAIN
Published: February 2019

Article 31 of the Code allows to form a species or subspecies from a personal name, using a nomen in the genitive case. Some zoologists have construed this rule as meaning that such nomina should always end in -i if dedicated to a man, in -ae if dedicated to a woman, in -arum to several women and in -orum to several persons including at least one man. They therefore proposed emendations to those nomina which they considered ill-formed under this interpretation. A detailed analysis shows that the latter is wrong, and that the original spelling (including its ending) of any new nomen based on a personal name should not be modified (except possibly in a few very rare cases). New spellings proposed by some authors for the reasons above are unjustified emendations, with their own authors and dates. Some problems related to homonymy in nomina based on personal names are also discussed. In conclusion, I propose a rewording of a few Articles of the Code to remedy some of the ambiguities pointed to by this analysis.
Stomatopod and decapod crustaceans from Camamu Bay, state of Bahia, Brazil
Authors: DE ALMEIDA ALEXANDRE OLIVEIRA , GUERRAZZI MARIA CECQLIA , COELHO PETR]NIO ALVES
Published: February 2019

Camamu Bay, located on the central coast of the state of Bahia, Brazil (13°47’ to 14°10’S), is the third-largest Brazilian bay. It is included in a zone that perhaps constitutes the last unexplored frontier on the Brazilian coast, situated between Todos os Santos Bay in Bahia, and the city of Vitória in Espírito Santo. Moreover, this zone coincides with an area of remarkable zoogeographical interest, the transition zone between the Brazilian and Paulista provinces. Camamu Bay contains a wide diversity of marine environments such as sandy beaches, rocky substrata, and mangroves, and it is still in a good state of preservation compared to other large Brazilian bays. The objective of this study was to survey the fauna of Crustacea (orders Stomatopoda and Decapoda) in Camamu Bay. The material analyzed was collected by trawling from July 2003 to September 2005. Voucher specimens were deposited in the collections of the Universidade Estadual de Santa Cruz and the Universidade Estadual do Sudoeste da Bahia, located in the cities of Ilhéus and Jequié (state of Bahia, Brazil), respectively. A total of 93 species, belonging to 35 families, was collected. The order Stomatopoda was represented by 3 families and 4 species; the order Decapoda was represented by 31 families and 89 species. The most important family in terms of number of species was Alpheidae, with 11 species. Of the total number of species, 88 are recorded from Camamu Bay for the first time, while 10 species are cited from the state of Bahia for the first time. The southern geographical distributional limits in the western Atlantic for the caridean Synalpheus pandionis and the brachyurans Macrocoeloma laevigatum and Elamena gordonae are extended.

Hypostomus rhantos (Siluriformes: Loricariidae), a new species from southern Venezuela
Authors: ARMBRUSTER JONATHAN W. , TANSEY LEIGH A. , LUJAN NATHAN K.
Published: February 2019

Hypostomus rhantos is described for a uniquely pigmented species of loricariid catfish from the upper Río Orinoco of Amazonas, Venezuela. Hypostomus rhantos can be separated from all other Hypostomus except H. micromaculatus by having its head and dorsal and lateral surfaces of body densely covered in very small spots (greater than 15 spots on the first plate in the dorsal series of specimens less than 100 mm SL vs. less than 10; greater than 30 spots in specimens greater than 100 mm SL vs. less than 15). The new species is distinguished from H. micromaculatus by having round spots (vs. longitudinally oval) that are unordered (vs. in longitudinal lines), by having well-developed keels on the lateral plates (vs. keels weak), by the presence of a ridge on the pterotic that is contiguous with the supraorbital ridge (vs. pterotic ridge absent), and by having the abdomen fully plated (vs. partially plated or naked).

Published: February 2019

During the latter stages of revisionary work on the genus Clinocera Meigen (Sinclair in prep.), the type series of most species were examined. In an earlier paper Sinclair (1999) compared European and North American types of the C. appendiculata group, which resulted in several redefinitions and synonyms. In this short correspondence, the results of an examination of a series of specimens from the original type series of C. rufipes Bezzi and the remaining syntype of C. nigra Meigen are also reported
A revision of the Neotropical spider genus Oligoxystre Vellard 1924 (Theraphosidae, Ischnocolinae)
Authors: GUADANUCCI JOSÉ PAULO LEITE
Published: February 2019

The genus Oligoxystre Vellard 1924 is revised. Pseudoligoxystre Vol 2001 is synonymized with Oligoxystre and its typespecies, P. bolivianum Vol 2001, is considered valid. The type-specimen of Oligoxystre auratum Vellard 1924, type-species by original designation, is considered lost. No additional material matching the original description was found and therefore the species is diagnosed from the original description. Four new species, all from Brazil, are also described: O. caatinga, O. dominguense, O. tucuruiense, and O. rufoniger. Data on natural history of O. bolivianum from field and captivity observations are presented. The genus Cenobiopelma Mello-Leitão & Arlé 1934 ) is based upon Cenobiopelma mimeticum Mello-Leitão & Arlé 1934 for which no type was ever designated and hence both are considered nomina nuda.
Morphology and morphogenesis of Strongylidium pseudocrassum Wang and Nie, 1935, with redefinition of Strongylidium Sterki, 1878 (Protista: Ciliophora: Stichotrichia)
Authors: DA SILVA PAIVA THIAGO , DA SILVA-NETO INÁCIO DOMINGOS
Published: February 2019

A population of the rare species Strongylidium pseudocrassum Wang and Nie, 1935, was discovered from a lagoon in the northern region of Rio de Janeiro, Brazil, and its morphology was investigated through protargol-impregnation, scanning electron microscopy and in vivo observations. Morphogenetic events of cell division and physiological reorganization were described for the first time to this species. It was found that S. pseudocrassum has the ventral cirral rows organized in the same manner as Pseudouroleptus caudatus Hemberger, 1985. However two independent primordia VI, one for the proter and other for the opisthe, are generated intrakinetally from the rightmost ventral cirral row. In addition, dorsal kineties replicate entirely “de novo” and do not fragment. Based on the data obtained, the genus Strongylidium was redefined and the species currently assigned to it were classified into five groups according to current knowledge on their ciliature and the combination S. lentum (Biernacka, 1963) nov. comb. is proposed.
A new and distinctive species of the hermit crab genus Catapaguropsis (Crustacea: Decapoda: Anomura: Paguridae) from the South China Sea
Authors: MCLAUGHLIN PATSY A. , LEMAITRE RAFAEL
Published: February 2019

The diagnosis of the recently described hermit crab genus Catapaguropsis Lemaitre & McLaughlin, 2006 is emended to accommodate a second distinctive new species, Catapaguropsis brucei n. sp., which does not exhibit the sexual dimorphism described for the type species, C. queenslandica Lemaitre & McLaughlin, 2006. Catapaguropsis brucei n. sp. is characterized by the marked reduction, in both sexes, of the posterior portions of the pleons, uropods, and telsons that are encased by cnidarians. In addition to the description and illustrations, this new species is compared and contrasted with species of other pagurid genera that occupy atypical carcinoecia.

Dorsal views of all species are presented as photographs, terminalia of both sexes illustrated, and distributions mapped. The larvae of this genus are borers of at least 31 genera of trees and parasitic plants in 15 families (Asteraceae, Betulaceae, Casuarinaceae, Cupressaceae, Fabaceae, Loranthaceae, Myrtaceae, Pittosporaceae, Proteaceae, Rhamnaceae, Rosaceae, Rutaceae, Sapindaceae, Sterculiaceae, and Xanthorrhoeaceae), including some economically important crops such as citrus, lychee (or litchi), peach, plum, and apricot. Several species are important pests of orchards. Uracanthus adults visit flowers of various tree species and are attracted to the light.
A revision of the Neotropical nursery-web spider genus Architis (Araneae: Pisauridae)
Authors: SANTOS ADALBERTO J.
Published: February 2019

The spider genus Architis Simon, 1898 is revised, resulting in sixteen species distributed from Panama to southern Brazil, all herein diagnosed, described and illustrated. Pisaurina brasiliensis Mello-Leitão, 1940 is transferred to Architis and considered a senior synonym of A. sinops Carico, 1989. The females of A. capricorna Carico, 1981 and A. robusta Carico, 1981 are described and illustrated for the first time. Architis nitidopilosa Simon, 1898 is considered a junior synonym of A. tenuis Simon, 1898 (the type species of the genus) and A. suarez Carico, 1989 a junior synonym of A. cymatilis Carico, 1981. The remaining species, A. ikuruwa Carico, 1981; A. tenuipes (Simon, 1898) and A. helveola (Simon, 1898) are redescribed and illustrated. Architis paulistana Mello-Leitão, 1917 is synonymised with Aglaoctenus lagotis (Holmberg, 1876) (Lycosidae: Sosippinae) based on its original description and type locality. Eight new species are described: A. erwini sp. nov., based on male and female specimens from Ecuador; A. comaina sp. nov. (male and female) and A. dianasilvae sp. nov. (female only) from Peru; A. maturaca sp. nov. (male and female) and A. altamira sp. nov. (female only) from Brazilian Amazonia; A. colombo sp. nov. (male and female), A. fritzmuelleri sp. nov. (female only) and A. turvo sp. nov. (female only) from southern and southeastern Brazil.
Poorly known Ascidiacea collected in the vicinity of the Commander Islands and East Kamchatka, NW Pacific
Authors: SANAMYAN KAREN , SANAMYAN NADYA
Published: February 2019

Deep-water Ascidia escabanae known previously only from Escabana Trough, NE Pacific and Ciona pomponiae, originally described from Galapagos Islands are recorded at abyssal and bathyal depths in the region of Commander Islands and East Kamchatka in NW Pacific. Ciona gefesti is a junior synonym of C. pomponiae. The northern Atlantic species C. gelatinosa Bonnevie, 1896 (previously thought to be a subspecies of C. intestinalis and related to the Pacific Ocean C. mollis) is redescribed here and shown to be a distinct species. Also discussed are several littoral and bathyal Molgula spp. considered previously as closely related or possibly conspecific that are shown here to be separate species readily distinguished by their gonads. Molgula beringense sp.n. is described from the vicinity of the Bering Island.
Parastenocarididae (Crustacea, Copepoda, Harpacticoida) of India: description of Parastenocaris mahanadi n. sp., and redescription of P. curvispinus Enckell, 1970 from hyporheic habitats
Authors: REDDY YENUMULA RANGA , DEFAYE DANIELLE
Published: February 2019

Only four species of the genus Parastenocaris Kessler, 1913, were previously known from India: P. curvispinus Enckell, 1970, P. gayatri Ranga Reddy, 2001, P. savita Ranga Reddy, 2001, and P. sandhya Ranga Reddy, 2001. A fifth species, Parastenocaris mahanadi n. sp., is here described from the hyporheic habitat of the River Mahanadi near Raipur city in the State of Chhatisgarh, central India. This is the first Indian representative of the minuta species-group. It can be distinguished from the other members of this group by a unique combination of morphological characters, especially of the male: fifth antennular segment bearing an extraordinarily long aesthetasc and seventh segment without apophysis; caudal rami as long as anal somite and over four times as long as their maximum width; lateral setae inserted at about distal third of rami; anal operculum smooth; leg 4 bearing two chitinized, claw-like spines at distal inner corner of basis; endopodite small, 0.4 as long as first exopodite segment and ornamented with two groups of long spinules; leg 5 produced into smooth, slender, acute, spinous process at distal inner corner, and with only three setae. Parastenocaris curvispinus, which was originally incompletely described from Sri Lanka by Enckell (1970), is redescribed from several hyporheic habitats. This highly variable species, which was found co-occurring, inter alia, with P. mahanadi n. sp., is the dominant and most wide-spread parastenocaridid in the hyporheic habitats of peninsular India. Following the recent resurrection of the genus Remaneicaris Jakobi, 1972, the taxonomic position of this species is reviewed. Furthermore, the distribution of the Indian parastenocaridids is briefly discussed.

Authors: LUNASCHI LÍA I. , DRAGO FABIANA B.
Published: February 2019

A summary of the literature on the digeneans of wild mammals in Argentina is presented. This is the first compilation of 51 parasitological papers published from 1909 to present. This review includes 26 native species and two introduced species (1 Artiodactyla, 6 Carnivora, 6 Cetacea, 3 Chiroptera, 2 Didelphimorphia, 1 Primate, 8 Rodentia and 1 Lagomorpha) and contains 42 species of adult digeneans belonging to 32 genera and 18 families, of which 9 species (21%) were recorded as new species. The present review provides data on hosts, geographical distribution, site of infection, life cycle, the location of material deposited in Helminthological Collections and references for the parasite species arranged by families. A host/parasite list is also provided. In addition, Gymnoacetabulum n g. is proposed to replaced the genus Suttonia Lunaschi, 2002 (Lecithodendriidae) from bats, which is preoccupied by Suttonia Smith, 1953 (Perciformes, Serranidae).

Authors: CÁRDENAS-ROJAS DIANA R. , RABANAL FELIPE , FORMAS J. RAM[N
Published: February 2019

The tadpole of Hylorina sylvatica is redescribed. The current description includes larval external morphology, internal oral features examined by SEM, and description of the chondrocranium and hyobranchial apparatus. The external and internal characteristics of the tadpoles of H. sylvatica are compared with others members of the subfamily Alsodinae (family Cycloramphidae) and used to improve the generic diagnosis which until now has been based on adult morphology.

Authors: BYRKJEDAL INGVAR , ORLOV ALEXEI M.
Published: February 2019

Cottunculus tubulosus n.sp. is described from one specimen caught in the summer of 2004 in the Northeast Atlantic, at about 2000 m depth in the Mid Atlantic Ridge. The species is characterised by a slender body, a long head, large pointed cranial spines, large bony tubules along the lateral line, prominent dermal prickles along the back, dorsal and anal fins set far posterior, a short caudal peduncle, and no banded colour patterns. From morphological characters, the species seems closely related to the South African species C. spinosus.
One new species of scorpion belonging to the genus Euscorpiops Vachon, 1980 from South China (Scorpiones: Euscorpiidae, Scorpiopinae)
Authors: ZHU MING-SHENG , ZHANG LU , LOURENÇO WILSON R.
Published: February 2019

A new species of scorpion, Euscorpiops yangi sp. nov. (Euscorpiidae) is described from Maguang County, Yunnan Province, China. The new species can be characterized by 18 external trichobothria (5 eb, 2 esb, 2 em, 4 est, 5 et) and 9 to 10 ventral trichobothria in the pedipalp patella; a narrow and elongated chela with a length vs width ratio equal to 3.4 on males and 3.3 on female; cheliceral movable finger with 5 basal teeth on ventral edge.
A new species of Dactylopusioides (Copepoda: Harpacticoida: Thalestridae) infesting brown algae, and its life history
Authors: SHIMONO TAKAKI , IWASAKI NOZOMU , KAWAI HIROSHI
Published: February 2019

A new species of harpacticoid copepod, Dactylopusioides malleus sp. nov., belonging to the family Thalestridae is described from central Japan. The species is obligately endophagous in dictyotalean brown algae (Dictyota dichotoma (Hudson) J.V. Lamouroux, Dictyota maxima Zanardini and Dictyopteris undulata Holmes). The species nests by burrowing into the algal tissue during the copepod naupliar stages, while copepodids and adults reside in a dome-shaped, transparent capsule made of mucus and formed on the algal tissue. In laboratory experiments, the new species progressed through its complete life cycle (i.e. from egg to adult) while feeding only on unialgal dictyotalean tissues; this confirmed the obligate relationship with the host. The new species shares the following morphological characters with other species of Dactylopusioides: 1) antennary exopod 1-segmented; 2) first segment of P1 endopod in female elongated with a long seta on the inner proximal margin; 3) baseoendopod and exopod of P5 in female with five setae. It differs from other species in the following ways: 1) antennary exopod with six setae; 2) a stout hammer-shaped inner spine on the basis of P1 in male; 3) terminal short seta on third segment of P2 endopod in male is plumose.
The identity and taxonomic position of Pleias Kirkaldy, 1901 (Hemiptera: Heteroptera: Reduviidae: Emesinae)
Authors: RÉDEI DÁVID
Published: February 2019

Based on the examination of the holotype, Pleias ritsemae Kirkaldy, 1901 (Heteroptera: Reduviidae: Emesinae: Leistarchini), is redescribed and figured. No generic differences can be found between Pleias Kirkaldy, 1901 and Bagauda Bergroth, 1903, consequently the latter is a junior synonym of Pleias. Reversion to the senior name Pleias would require that the several nominal species currently included in Bagauda be transferred to the nominal genus Pleias. Therefore, in order to preserve stability, no nomenclatural changes are proposed in this paper, but an application has been submitted to the International Commission on Zoological Nomenclature to give Bagauda precedence over Pleias. Although congeneric, Pleias ritsemae is not conspecific with any other species currently in Bagauda and its differentiating characters are discussed. The following new synonymy is proposed: Ploiaria perfuga Miller, 1941, syn. n. = Pleias ritsemae Kirkaldy, 1901.

Luciola aquatilis sp. nov., a common firefly in Thailand was formerly commonly misidentified as Luciola brahmina Bourgeois. Other Luciola species that resemble L. aquatilis are discussed, as well as past confusion concerning their taxonomic affinities.
Two new species of Lankascincus (Squamata: Scincidae) from Sripada Sanctuary (Peak Wilderness), in Sri Lanka
Authors: WICKRAMASINGHE L. J. MENDIS , RODRIGO ROSHAN , DAYAWANSA NIHAL , JAYANTHA U. L.D.
Published: February 2019

The present work describes two new species of Lankascincus from the Sripada Sanctuary (Peak Wilderness Sanctuary) of Sri Lanka. Lankascincus sripadensis sp. nov. is the largest member in the genus and it is morphologically closely related to L. deignani (Taylor 1950). But Lankascincus sripadensis sp. nov. can be clearly distinguished from other members of the genus, by having three loreal scales, posterior loreals larger than the anterior in longitudinal axis, prefrontal and upper anterior preocular touching posterior loreal; 2 nd , 3 rd supralabials and 1 st subocular scale touching lower posterior loreal; males with pale brown throat and the ventral head; a dark brown stripe in the light brown background on the dorsal body, divided nasal. The other new species, Lankascincus munindradasai sp. nov. is morphologically closely related to L. taprobanensis (Kelaart, 1854) and can be clearly distinguished from other member of the genus, by having one loreal scale, the loreal is touching the prefrontal, frontonasal, nasal, 1 st and 2 nd supralabial scales, upper and lower preoculars; the loreal is larger than the longitudinal axis.
Genetic and morphological differentiation of Mosor rock lizards, Dinarolacerta mosorensis (Kolombatović, 1886), with the description of a new species from the Prokletije Mountain Massif (Montenegro) (Squamata: Lacertidae)
Authors: LJUBISAVLJEVIĆ KATARINA , ARRIBAS OSCAR , DšUKIĆ GEORG , CARRANZA SALVADOR
Published: February 2019

A new species of lacertid lizard of the genus Dinarolacerta is described from the Prokletije Mountain Massif, Montenegro. This new species, Dinarolacerta montenegrina sp. nov., is characterized by its relatively small size, by usually having only one postnasal scale on one or on both sides of the head, a relatively lower number of temporal and postocular scales and a relatively high number of ventral scales. Osteologically, it is mainly characterized by the complete absence of the anteromedial process in the postocular bone, and more reduced supraocular osteoderms. The phylogenetic analysis using partial sequences of the mitochondrial 12S rRNA gene supports the specific status of D. montenegrina sp. nov. and shows that it represents an old independent lineage that separated from its sister species, D. mosorensis, in the late Miocene. The Morača river canyon may have acted as a geomorphological and climatic barrier causing the speciation between the two species of Dinarolacerta. The discovery of this new species endemic to the Balkan Peninsula highlights the importance of the Dinarides as one of the main European hotspots of biodiversity. This high level of endemicity in the Dinaric region is probably the result of both its geographic situation and its complex geological history and morphology.
A new species of Hydrodynastes Fitzinger, 1843 from central Brazil (Serpentes: Colubridae: Xenodontinae)
Authors: FRANCO FRANCISCO L. , FERNANDES DANIEL S. , BENTIM BRUNO M.
Published: February 2019

A new species of Hydrodynastes is described from the State of Tocantins, Central Brazil. The new species is distinguished from all congeners by having a melanistic color pattern, with head and dorsum of the body mostly dark-brown to black; absence of postocular stripe; venter grayish-brown, with dark rounded blotches outlining two lateral stripes which become gradually paler towards the posterior region of the belly, disappearing after midbody. Comparisons of the new species are made with others species of the genus and its affinity with H. gigas is suggested based on meristic and hemipenial characters
Micralestes (Characiformes, Alestidae) of the lower Congo River, with a description of a new species endemic to the lower Congo River rapids in the Democratic Republic of Congo
Authors: STIASSNY MELANIE L.J. , MAMONEKENE VICTOR
Published: February 2019

A new dwarf alestid from the vicinity of Inga on the lower Congo River, Bas Congo Province, Democratic Republic of Congo is described. Assignment of the new taxon to the poorly defined genus, Micralestes, is discussed and justified on the basis of available morphological character data. With the recognition of Micralestes schelly sp. nov., a total of six Micralestes are now known to inhabit the 350 km stretch of the Congo River from Pool Malebo to Boma near the river’s estuary. These are Micralestes acutidens (Peters, 1852), Micralestes humilis Boulenger, 1899, Micralestes lualabae Poll, 1967, Micralestes holargyreus (Günther, 1873), Micralestes stormsi Boulenger, 1902, and the new species Micralestes schelly. Of these Micralestes schelly and Micralestes holargyreus are considered herein as restricted-range endemics of the lower Congo River. An illustrated key to Micralestes of the lower Congo River is provided.
