Some European Processidae (Crustacea,Decapoda, Caridea)

Summary

The name Processa canaliculata Leach has been applied to a species other than that to which the holotype belongs. The species P. canaliculata Nouvel & Holthuis non Leach has no valid name; it is re-named P. nouveli, with type material from Monaco.

P. nouveli and P. canaliculata have been considered to be conspecific by one recent author. New characters for their separation are described from Irish Sea material.

The northern form of P. nouveli differs from the Mediterranean form sufficiently to be placed in a separate subspecies. The name P. nouveli holthuisi is proposed for it, with type material from the Irish Sea.

The distribution of the four species and subspecies of Processa known to occur in northern Europe is reviewed.     

A new species of Didogobius (Teleostei: Gobiidae) from the Adriatic Sea

Didogobius schlieweni sp. nov. is described from a single specimen collected among pebbles in shallow water at Unije island, near Cres, in the northern Adriatic Sea. The holotype has vivid dark and pale patterning, and is assigned to Didogobius on the basis of head neuromast patterns and meristic features. Diagnostic values of the latter are D2 I/12, A I/11, P 17, and LL 55–56. A key to species of the Chromogobius and Didogobius complex is provided.     

On the systematics,distribution and conservation status of Ichthyophis longicephalus Pillai, 1986 (Amphibia: Gymnophiona: Ichthyophiidae)

The caecilian Ichthyophis longicephalus was described in 1986 based on a single specimen. Only one specimen has been referred subsequently to this species, and the validity of that referral has been questioned. Seven specimens discovered in 2009–2010 at two new localities and two specimens collected in 1990 from a third locality are referred here to I. longicephalus. These specimens are described and compared with the poorly preserved holotype. Mitochondrial DNA data are consistent with the interpretation that the new specimens represent a single species distinct from (and most closely related to I. tricolor among) sampled congeners. The previously referred specimen, from c. 320 km south of the type locality, is not I. longicephalus and probably represents an undescribed species. The “rediscovery” of I. longicephalus in forests and disturbed habitats indicates that the species probably could be transferred from the Data Deficient to the Least Concern category of the IUCN Red List.     

Copepods of the genus Colobomatus (Poecilostomatoida: Philichthyidae) from fishes of the family Sillaginidae (Teleostei: Perciformes)

Six species of Colobomatus, five of which are new to science, were found in a survey of 26 species of sillaginid fishes in the Indo-west Pacific. Three of the species are closely related and occur in the head cavities of various species of their hosts. Colobomatus sillaginis West, 1983 is recorded in Sillaginodes punctata and 12 species of Sillago, from around the coast of Australia and in the Gulf of Thailand, representing many new host and locality records. Female C. asiaticus sp. nov. are described from southeast Asia and the Persian Gulf, in three species of Sillago. Female C. arabicus sp. nov. are described from two species of Sillago occurring only in the Persian Gulf. A second intrageneric grouping of three species of Colobomatus inhabits a different microhabitat: tubes of the lateral line scales. Each of these species infects several sillaginid fishes, and in contrast to members of the first species-group they are entirely allopatric with each other. In Australia, female C. fulloonae sp. nov. are described from three species of Sillago in northern waters, and female C. charleah sp. nov. are described from two species of Sillago and Sillaginodes punctata in southern waters. Female C. westi sp. nov. are described from three species of Sillago in the waters of eastern Asia (Japan, Korea and China). Only one male specimen of each of C. arabicus sp. nov., C. charleah sp. nov. and C. westi sp. nov. was found.     

A new species of the subterranean genus Oodinotrechus Uéno, 1998, from northern Guangxi,China, with additions to the generic diagnosis (Coleoptera: Carabidae: Trechinae)

A new eyeless species, Oodinotrechus liyoubangi n. sp, is described from northern Guangxi. All specimens of this interesting species were collected in three limestone caves in Mulun National Nature Reserve of northern Guangxi, southern China. It is the second species for the genus Oodinotrechus Uéno, 1998, distinguished from the type species O. kishimotoi Uéno, 1998 by its visible scutellum and pronotal structure. Several additional diagnostic characters for the genus and a geographical distribution map for both known species are also provided.

A revision of the Fabriciin genus Augeneriella Banse, 1957 (Polychaeta: Sabellidae)

The Sabellidae polychaete genus Augeneriella Banse is revised based on a reexamination of the type material of most species. Augeneriella hummelincki hummelincki Banse is shown to have vascularized, ventral filamentous appendages which can display up to four branches in a pectinate arrangement, as opposed to only a single dichotomy as originally described. The status of A. hummelincki indica Banse is discussed. The species A. bansei Hartmann-Schröder is based on a single, probably aberrant, specimen in which ventral filamentous appendages are unbranched. Additional material will likely show that this species displays the typical branched condition for ventral filaments. Augeneriella dubia Hartmann-Schröder can be ascribed to an undescribed genus which has been found in Atlantic, Indian, and Pacific Oceans. Two new species of Augeneriella from the Aldabra Atoll, Indian Ocean, are described.     

On the new goby,Ctenogobius veliensis (Teleostei: Gobiidae) from the South-West coast of India

Summary

Ctenogobius veliensis, a new species of gobiid fish is described from the South-West coast of India. The characters of the fish conform to those of the genus Ctenogobius Gill but differ markedly from those of other recorded species of the genus. Apart from the usual, external morphological, morphometric and metistic characters, several other features such as the cephalic-lateralis system, skeletal features and morphology of the alimentary canal are also studied and have been found to be of significance for identifying the species. The fish shows distinct sexual dimorphism in many features.     

Observations on the “tenuis group” (Eutardigrada,Macrobiotidae) and description of a new Macrobiotus species

A new species of the tardigrade genus Macrobiotus is described. The species, designated M. ciprianoi n. sp., was isolated from a mixture of Provence broom leaf litter and mosses, and from rock mosses collected in the Sierra de Guadarrama, Madrid (Spain). Given that Macrobiotus ciprianoi n. sp. shares several characters to members of the “tenuis group”, we assessed the taxonomic homogeneity of the group. The new species differs from those of the “tenuis group” according to a unique set of characters related with claw shape, features of the buccal‐pharyngeal apparatus, and egg morphology. Our analysis of holotypes and/or paratypes of “tenuis group” species and other Macrobiotus species with similar characters (M. bondavallii and M. caelicola) reflects the heterogeneity of this group of species as currently described.     

First record of the subfamily Coelotinae in Laos,with review of Coelotinae embolus morphology and description of seven new species from Laos and Vietnam (Araneae,Amaurobiidae)

First records of Coelotinae are reported from Laos. Five new species of the genus Draconarius are described from the northern Luang Nam Tha Province: Draconarius bounnami sp. nov. (male), D. latidens sp. nov. (female), D. postremus sp. nov. (male, female), D. songi sp. nov. (male) and D. tabularis sp. nov. (female). In addition, two new Coelotinae species are described from Vietnam: D. hanoiensis sp. nov. (female) and D. huongsonensis sp. nov. (female). Of the 429 currently valid Coelotinae species, 154 of them have only females described (36%). The embolus characteristics of those with males described (275 species, 64%) are reviewed. Two characters have been found that might be informative for the estimation of phylogeny, and their congruence with the current Coelotinae classification system is discussed. One character is the point from which the embolus arises and another is the embolus shape.     

The female genitalia of Gonioctena,subgenus Spartoxena (Coleoptera: Chrysomelidae)

The taxonomy of the eight species of Gonioctena Chevrolat belonging to the subgenus Spartoxena Motschulsky is mostly based on male genitalia due to the unsuitability of external characters (i.e. coloration patterns) for identification. In order to provide similar diagnostic characters for both genders, the female genitalia of the eight species are described and illustrated. Considering the lack of spermathecae within the genus, the shapes of tergite 8, and sternites 8 and 9 have been explored as possible diagnostic characters. These structures present marked differences between taxa and simultaneously stability among individuals of each species, and thus they are very useful for taxonomic purposes. A key to the females of the subgenus Spartoxena is provided, and figures of tergite 9, and sternites 8 and 9 of each species are included.     

A new species of the genus Gorgodera (Trematoda: Gorgoderidae), from two species of Anura from the Eastern Pyrenees

Summary

A bladder fluke from two species of Anura, Rana temporaria temporaria L. and Bufo bufo bufo L., is described and erected as a new species under the name Gorgodera euzeti sp. nov.     

A new genus of Neotropical whitefly,secreting blue-iridescent wax (Sternorrhyncha,Aleyrodidae, Aleurodicinae), and its parasitoids (Hymenoptera,Aphelinidae)

Azuraleurodicus pentarthrus Martin gen. and sp. n. is described from three different host plant families in Central and northern South America. Adults of both sexes were reared in culture and adult characters are discussed in addition to those of puparia. The systematic position of Azuraleurodicus within the Aleurodicinae is discussed. One new combination, Aleuronudus ferrisi (Sampson and Drews) comb. n., is here proposed in the course of discussion. The secretion of blue wax by whiteflies is discussed and illustrated by colour photographs. Two species of hymenopterous parasitoids, Dirphys aphania Polaszek sp. n. and Encarsiella pithecura, Polaszek sp. n. emerged from puparia of Azuraleurodicus pentarthrus and are here described.     

Four new freshwater gobies of the genus Rhinogobius (Teleostei: Gobiidae) from northern Vietnam

Four new freshwater gobies of the genus Rhinogobius Gill, were collected from the river running into the Gulf of Tonkin in northern Vietnam. They are Rhinogobius boa new species, Rhinogobius variolatus new species, Rhinogobius virgigena new species and Rhinogobius sulcatus new species. These four new species can be distinguished from other congeneric species by a combination of characters such as the meristic features, shape of body, shape of first dorsal fin and coloration pattern.     

A description of the song of Chorthippus cazurroi (Orthoptera: Acrididae) with notes on its taxonomic position and distribution

The highly characteristic calling and courtship songs of Chorthippus cazurroi are described for the first time and are used, together with a number of morphological characters, as a basis for discussing the differences between this species and C. pullus, C. pulloides, C. nevadensis and Omocestus llorenteae, with which it has been or might be confused. Despite the superficial resemblance between cazurroi and these species, clear and reliable characters are described for distinguishing it from all of them. The distribution of cazurroi is also discussed and it is suggested that its inclusion in the Libro Rojo de los Ortópteros Ibéricos as extinct or in danger is, as the authors of that work suspected, unduly pessimistic. A lectotype is designed from the type material of C. cazurroi.     

Composition of meiobenthonic Platyhelminthes from brackish environments of the Galician and Cantabrian coasts of Spain with the description of a new species of Djeziraia (Polycystididae,Kalyptorhynchia)

From 1997 to 1999, the fauna of free‐living Platyhelminthes of the rias ecosystem was studied along the Galician and Cantabrian coast in northern Spain. In total, 72 platyhelminth species are listed in this study. Forty‐two species represent new records for the Iberian Peninsula, three of which represent new genera records. A new species belonging to the genus Djeziraia (Polycystididae, Kalyptorhynchia), Djeziraia longistyla sp. nov., is described in this paper. In this broad‐scale study, a large data set (27 localities) of the estuaries of northern Spain allowed an analysis of the turbellarian species assemblages and the relation of species distributions to salinity, conductivity, oxygen, temperature, and sediment characteristics. Species assemblages (species diversity) of each habitat of the brackish water ecotone are shown. The present study contributes to knowledge on the ability of adaptation of free‐living Platyhelminthes to regimes of brackish water ecotones.     

Revision of the American Pupisoma species (Gastropoda: Pupilloidea)

The American species of Pupisoma Stoliczka (Gastropoda: Pupilloidea) are revised. Five species are recognized. Pupisoma puella Hylton Scott has been synonymized with P. dioscoricola (C. B. Adams). This species occurs from southern USA through the Caribbean and Central America to the Galapagos Islands and to southern Brazil and northern Argentina. Pupisoma galapagorum Pilsbry, P. bailyi Pilsbry, and P. latens Hylton Scott have been synonymized with P. comicolense H. B. Baker. This species is distributed from Mexico to the Galapagos Islands, southern Brazil, and northern Argentina. Pupisoma costulata sp. n. from Andean forests in Colombia is described as new. The range of P. macneilli (Clapp) extends from southern USA through the Caribbean and Central America to southern Brazil and northern Argentina. A neotype has been designated for P. mediamericanum Pilsbry. Pupisoma michoacanense Pilsbry is a synonym of this species. This species occurs from Mexico to Colombia and on Jamaica.     

News from a small island – first record of a freshwater shrimp (Decapoda,Atyidae, Caridina) from Peleng,Banggai Islands,Indonesia

The Indonesian island Sulawesi is well known for its fascinating fauna. Among the atyid and palaemonid freshwater shrimps described from Sulawesi are also a number of endemic species. In contrast, freshwater shrimps have never been reported from the nearby and smaller Peleng Island. Here we describe Caridina thomasi sp. nov. as a first record of an atyid freshwater shrimp from Peleng and compare it with atyids from Sulawesi and other localities. The new species is probably endemic to the island and shows some characters never described in the genus Caridina before. However, a molecular phylogeny of atyid shrimps from the Indo‐West Pacific based on mitochondrial DNA (16S) places C. thomasi within a clade of typical species of Caridina. We tentatively assign the new species to the genus Caridina and discuss the possibility of future changes in the classification of species in this genus.
