Rissoidae is a family of small to minute marine gastropods distributed worldwide. The generic composition of the family was revised by Ponder (1984) based on characters of external morphology and internal anatomy. However, species level taxonomy within the family is still based mainly on conchological characters, which are less informative and usually not sufficient for resolving the systematic relationships of species. Northern Atlantic representatives of the family were revised by Warén (1974; 1996) and Bouchet & Warén (1993) based on shape and sculpture of both proto- and teleoconch, and were suggested to be members of several genera, widely distributed in boreal or even tropical Atlantic environments...

The genus Holoaden Miranda-Ribeiro (Anura, Craugastoridae, Holoadeninae) includes four species endemic to the southeastern Brazilian Atlantic Forest, which occur in cloud forests at high elevations (Lutz 1958, Pombal et al. 2008, Martins & Zaher 2013). Out of these, two species are considered threatened by Ministério do Meio Ambiente (2014): H. bradei is classified as critically endangered (CR) and H. luederwaldti as endangered (EN). Holoaden bradei might be already extinct in the wild, as it has not been recorded in the last 40 years in spite of intense scientific activity within its original distribution range (Rocha & van Sluys 2004)...

There has been much confusion around the identity of Hypselobarbus pulchellus, an endemic large barb of the Western Ghats. Recent works highlighted the fact that it is likely that two similar-looking species have been considered as H. pulchellus. A genetic analysis helps differentiate the two forms: viz., H. pulchellus and a new species, here described as H. bicolor sp. nov. Hypselobarbus bicolor can be distinguished from all other species of Hypselobarbus based on a combination of the following characters: two pairs of barbels, lateral line complete, with 34-36+1-2 pored scales, ½6/1/3½ scales in the transverse row; 11-12 predorsal scales; last simple dorsal ray weak, dorsal fin with 9½ branched rays, gill rakers short and simple, 4-6+11-12 on first gill arch; proximal end of fifth ceratobranchial slightly curved, with 5+3+2 teeth; overall coloration dark grey with an ill-defined silver- or bronze-coloured band running along length of body, two scales high, on lateral-line scale-row and row above it; fins devoid of any markings; and small, closely-placed tubercles restricted to the tip of the snout in large males...

The discovery of new vertebrate species in developed countries is still occurring at surprising rates for some taxonomic groups, especially the amphibians and reptiles. While this most often occurs in under-explored areas, it occasionally still happens in well-inhabited regions. We report such a case with the discovery and description of U. mahonyi sp. nov., a new species of frog from a highly populated region of New South Wales, Australia. We provide details of its morphology, calls, embryos and tadpoles, and phylogenetic relationships to other species of eastern Uperoleia...

The thread-legged assassin bug genus Proguithera Wygodzinsky, 1966 of the emesine tribe Leistarchini (Hemiptera: Heteroptera: Reduviidae) is recorded from Japan for the first time, and a new species P. kiinugama sp. nov., the third representative of this genus, is described based on specimens from Ishigaki-jima Island in the Ryukyu Islands. This new species can be distinguished from its congeners primarily by the absence of a median longitudinal sulcus on the anterior pronotal lobe, forewing with an incomplete cross vein connecting the M+Cu vein and a submarginal vein basad of the discal cell, and the anteroventral series of the profemur consisting of about 30 spine-like setae...

The genus Scalarispongia was raised to gather species formerly allocated in Cacospongia with rectangular fibrous skeleton of cored primary fibers and uncored secondary fibers. Species of the genus Thorecta have a similar skeletal architecture, but the presence of a dermal armour distinguishes them from Scalarispongia. Here we describe two new species of Scalarispongia from northeastern Brazil and transfer Scalarispongia cincta to Thorecta cincta. Scalarispongia tubulata sp. nov. is thick encrusting to cushion-shaped, has tubular projections with thin walls, and surface irregularly microconulose...

Sphaeropoeus hercules Brandt, 1833, the type species of one of the oldest genus names in Sphaerotheriida, is redescribed for the first time based on its fragmented type specimen. While damaged, the specimen shows characters clearly different from other, diverse and similar genera of the family Zephroniidae, such as Zephronia Gray, 1832 and Castanotherium Pocock, 1895. S. hercules has a record number of >180 apical cones on the antennae, more than any other millipede. The species, together with another species of the genus Castanotherium, C...

Trichodiniasis of fishes cause economic losses in the fish industry through mortality and decrease growth rate. Very few studies of these ectoparasites have been made in India. A comprehensive icthyoparasotological survey in some ornamental fish farms of different parts of India has been done since March 2014-May 2015. During the study these trichodinid parasites have been identified from the gills of Oranda Gold Fish (Carassius auratus auratus L.). They are Trichodinella epizootica, Tripartiella viz. Tripartiella bulbosa, Tripartiella copiosa and Tripartiella obtusa...
