The genus Cotylopus (Teleostei: Gobioidei) endemic to the rivers of islands of the Indian Ocean with description of a new species from Mayotte (Comoros)

Cotylopus rubripinnis, new species, is described on the basis of nine specimens collected from the Island of Mayotte (Comoros), Indian Ocean. Cotylopus rubripinnis differs from the only other known species in the genus (C. acutipinnis Guichenot, 1863) in usually having fewer scales in lateral (LS), transverse back (TRB), transverse forward (TRF), and zigzag series (ZZ), and in having pectoral, dorsal and caudal fins reddish. The genus was previously only known from the Mascarene Islands (Réunion and Mauritius). The discovery of a second species for that rare and endemic genus 1400?km farther to the north‐west in the Indian Ocean is discussed.     

Gobiid fishes from the Cape Verde Islands,including two new species of Gobius (Teleostei: Gobioidei)

Ten species of gobiid fishes (Teleostei: Gobioidei) now listed from the Cape Verde islands fall into several zoogeographical categories, including tropical West African Bathygobius casamancus, Mauligobius nigri, Porogobius schlegelii (unconfirmed) and Vanneaugobius canariensis, tropical amphiatlantic B. soporator and Gnatholepis thompsoni, and Canarian Didogobius kochi. Two new species of the eastern Atlantic, predominantly temperate genus Gobius are described: G. ateriformis sp. nov. and G. tetrophthalmus sp. nov., known so far only from the Cape Verdes, but reported occurrence of the congeneric Atlantic-Mediterranean G. paganellus has not been confirmed. The pattern of free neuromast organs (sensory papillae) of the head lateral-line system in Mauligobius nigri and the habitat of this species are described for the first time and its distribution further discussed. Diversity of gobies and other inshore fishes at the Cape Verdes is briefly indicated.     

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.     

Systematics and phylogeny of Eodrepanus,a new Drepanocerine genus,with comments on biogeographical data (Coleoptera: Scarabaeidae: Oniticellini)

We describe here Eodrepanus gen. nov., currently comprising nine species, six previously assigned to the genus Drepanocerus and three described as new (namely, E. morgani sp. nov., E. paolae sp. nov. and E. coopei sp. nov.). Two of the new species have an Afrotropical distribution, while the last is an Eemian fossil species from England. Maximum parsimony was used to analyse reciprocal relationships among the species of Eodrepanus gen. nov., and four of the 24 species remaining in Drepanocerus. Support for these phylogenies was evaluated using the Bootstrap method and Bayesian inference as implemented in MrBayes. The biogeography of Eodrepanus gen. nov. was analysed using several different methods, namely, analysis of similarity (Ochiai Index), dispersal–vicariance analysis and parsimony analysis of endemicity.     

Considerations about the genus Pentoniscus Richardson, 1913 (Crustacea: Isopoda: Oniscidea) with description of a new species

The status of the neotropical genus Pentoniscus Richardson, 1913 is reconsidered and a diagnosis of this genus is given. It is shown that Pentoniscus Richardson, 1913 is a valid genus and not a synonym of Philoscia Latreille, 1804 as discussed by Schultz (1968). The type species, Pentoniscus pruinosus Richardson, 1913 is redescribed and for the first time figured in detail. A new species of Pentoniscus Richardson, 1913 is described from Costa Rica, Central America, which differs remarkably from its congeners in being unpigmented and blind.     

The genus Bassus Fabricius, 1804 (Hymenoptera: Braconidae: Agathidinae) in China,with description of three new species

Five species of Bassus Fabricius, are recognized to occur in China, of which three are new: Bassus guangxiensis sp. nov., Bassus levisulcus sp. nov. and Bassus robustus sp. nov. The new species are described and fully illustrated. Bassus albozonatus van Achterberg & Long, is recorded from China for the first time. A key to the Chinese species of the genus Bassus is provided.www.zoobank.org/urn:lsid:zoobank.org:pub:17297254-9E84-4D0F-AE8C-1F7264393137     

Description of Ghatiana,a new genus of freshwater crab,with two new species and a new species of Gubernatoriana (Crustacea: Decapoda: Brachyura: Gecarcinucidae) from the Western Ghat Mountains,India

A new genus of freshwater crab, Ghatiana, with two new species, Ghatiana aurantiaca and Ghatiana hyacintha, and a new species of Gubernatoriana Bott, 1970, are described from the Western Ghat Mountains in Maharashtra State, India. Ghatiana is most similar to Gubernatoriana by its wide, highly arched carapace and by the shape of the male abdomen. Nevertheless, the new genus can be distinguished from Gubernatoriana by the broadness of carapace, length of male abdomen, shape of sixth abdominal somite, length of telson and length of G1 terminal article. Ghatiana aurantiaca sp. nov. and G. hyacintha sp. nov. are distinguished by differences in body colour, carapace width, and G1 morphology, whereas Gubernatoriana triangulus sp. nov. is distinguished from two other known species [Gubernatoriana gubernatoris (Alcock, 1909) and Gubernatoriana pilosipes (Alcock, 1909)] by its triangular G1 subterminal segment and by its carapace morphology. Keys to the species of both the genera are provided.

Notes on the Amazonian genus Hyogonia China (Hemiptera: Cicadellidae: Proconiini) with a description of a new species

Oncometopia batesi Distant, described from northern Brazil (State unknown), is transferred to the genus Hyogonia China. Hyogonia brasiliana sp. nov. is described from Northern Brazil, Pará State, the easternmost record of the genus. The new species is easily distinguished from all other Hyogonia species by the following combination of characters: (1) pronotum without distinct transverse contrasting band; (2) pygofer with short processes that do not attain its apex; (3) both pairs of aedeagal atrial processes divergent and short, never longer than aedeagal shaft; and (4) aedeagal caudal pair of atrial processes with bases close to each other, appearing as a single bifurcated robust process. Hyogonia batesi and H. brasiliana, together with an unidentified female from Acre State, represent the first authentic records of the genus Hyogonia from Brazil. Previous records of H. reticulata (Melichar) and H. youngi Emmrich and Lauterer from Brazil are erroneous as their recorded locality ‘Cumbase’ is most probably located in Peru (San Martín Department). Other new records from countries and major federal divisions are noted as follows: the genus Hyogonia (unidentified species) from Barinas State (Venezuela); H. batesi from Ecuador (Orellana Province); H. reticulata from Amazonas and Junín Departments (Peru); and H. youngi from Ecuador (Napo Province). A key to the known species of Hyogonia is provided.     

Taxonomy of the genus Tantunema Siddiqi, 1982 (Dorylaimida: Tylencholaimidae) with description of one new and two known species

One new and two known species of the genus Tantunema Siddiqi, 1982 are described and illustrated. Tantunema indicum sp. nov. is characterized by having a small body (length 0.32–0.45 mm); lip region cap-like, set off by slight constriction; odontostyle 6–7 µm and odontophore 8–10 µm long; pharyngeal expansion gradual, expanded part occupying about 35–41% of total neck length, lumen of posterior expanded part widened and thickened; female genital system mono-opisthodelphic, anterior genital branch absent; tail short, hemispheroid, 0.8–1.1 anal body diameter long. Tantunema pakistanense (Timm, 1964) comb. nov. (=Tylencholaimus pakistanensis Timm, 1964) and Tantunema intermedium (Peña-Santiago and Coomans, 1996) Andrássy, 2009 are redescribed. A diagnostic compendium and key to species of the genus is also provided.     

Revision of the genus Delopleurus Boheman (Coleoptera: Scarabaeidae: Scarabaeinae) with description of new species from Africa

The genus Delopleurus Erichson, 1847, is revised. Five new species are described from Africa: Delopleurus naviauxi sp. nov., Delopleurus krikkeni sp. nov., Delopleurus darrenmanni sp. nov., Delopleurus fossatus sp. nov. and Delopleurus pubescens sp. nov. One new synonymy is established (Delopleurus parvus (Sharp, 1875) = Delopleurus cardoni Paulian, 1934, syn. nov.). Lectotype of Delopleurus pullus Boheman, 1857, is designated. Delopleurus janssensi Frey, 1963, is transferred to the genus Metacatharsius Paulian, 1939. A key to the Delopleurus species and locality maps are given.

First record of a freshwater Pisionidae (Polychaeta): description of a new species from Panama with a key to the species of Pisione

A new species of Pisione Grube, 1857, Pisione garciavaldecasasi n. sp. (Polychaeta: Pisionidae) is described from several small rivers in Cobia Is., Pacific, off Panama. This is the first report of a freshwater Pisionidae and it is one of very few known species of true freshwater polychaetes. The species is characterized by large size, by dorsal cirri of setiger 2 and ventral cirri of setiger 1 only slightly elongated, by non-successive male copulatory organs, and by parapodia each with one compound seta with long blade and three others with short blades.     

Synopsis of the genus Pseudoperma Dillon and Dillon, 1946 (Coleoptera: Cerambycidae), with description of a new species

A synopsis of Pseudoperma is provided. This genus mainly differs from Onocephala and Stethoperma by the antennal tubercles well separated; antennae relatively short, in the female subequal to the body length; and scape and third antennomere subequal in length. Pseudoperma includes two species, P. chalcogramma (Bates, 1887) and P. patruelis (Breuning, 1940), both from Brazil; herein we describe one new species, Pseudoperma lingafelteri sp. nov. from Brazil (Rio de Janeiro). This species differs from its congeners mainly in having the frons and occiput covered with greyish pubescence, and the sides of the elytra with several interrupted or coalescent vittae. We provide new distribution data for Pseudoperma patruelis (Breuning, 1940) from Brazil, Minas Gerais, São Paulo and Santa Catarina, as well as illustrations and a key to the species of Pseudoperma.

The sentinel crabs of the genus Chaenostoma (Stimpson, 1858) (Crustacea: Brachyura: Macrophthalmidae), with description of a new species and new records

The genus Chaenostoma (Stimpson, 1858) so far includes four distinct species, i.e. C. boscii (Audouin, 1826), C. lisae (Poupin and Bouchard, 2010), C. punctulatus Miers, 1884, and C. sinuspersici (Naderloo and Türkay, 2011). Chaenostoma java n. sp. is here described as a fifth species from Java (Indonesia) easily distinguished from its congeners by the features of the male first pleopod, the penultimate segment of the male abdomen, and the unique female gonopore. The new species is most similar to C. lisae, but they differ in the morphology of the male chelipeds and female gonopores. Chaenostoma lisae is redescribed and recorded from Madagascar, Mayotte I. and New Caledonia. An identification key for the genus is provided.
