Caecidotea burkensis, a new species of subterranean asellid isopod, is described and illustrated from material collected from Lawson Cave, in Burke’s Garden, Tazewell County, Virginia. The type-locality in Burke’s Garden is located within the highest mountain basin in the southern Appalachians. Burke’s Garden is a unique, geologically isolated area encompassing one of the headwater streams of the New River basin. Phylogenetically, the isopod is a member of the forbesi Group, a clade comprised primarily of epigean species. The complex mountain valleys and coves of southwestern Virginia are an area of intense speciation among asellids that have produced a bizarre array of cavernicolous species belonging to groups of otherwise epigean isopods. In addition to a few subterranean species of the Caecidotea cannula and stygia Groups, the Lirceus hargeri Group possesses over a dozen species endemic to caves and springs in the region, mostly only now in the process of being discovered and described. With so much species richness, syntopy of two, or even three, asellid species is commonplace in caves and springs in southwestern Virginia.

Abstract Aegla lata Bond-Buckup & Buckup, 1994 is considered extinct in the type locality. New populations of this species, however, have been found in northern Paraná state, Brazil. We revised the taxonomy of A. lata based on morphological data obtained from the type material and specimens recently obtained from streams of the Tibagi River sub-basin, Paranapanema River basin, Upper Paraná Ecoregion. Moreover, Aegla jacutingan. sp. is described and illustrated. The new species resembles A. lata in the shapes of the body and chelipeds. Both species are nevertheless separated by particular morphological characters of the carapace, chelipeds, and epimeron as well as by molecular (COI mtDNA) differences. Both species can be distinguished from their congeners based on morphological and molecular evidence.

A new species of blind subterranean ground beetle in the genus Anillinus Casey is described from Florida. Anillinus albrittonorumsp. nov. (type locality: 6 miles NW High Springs, Columbia County, Florida) has a unique structure of female genitalia and occupies an isolated position within the genus. This new species is illustrated with images of the habitus, body parts, and male and female genitalia. Relationships of A. albrittonorum to other members of the genus are discussed.

We describe and name the second species of Phyzelaphryne (Brachycephaloidea, Eleutherodactylidae), from northwestern Brazilian Amazonia. Phyzelaphryne nimio sp. nov. is distinguished from its only congener, Phyzelaphryne miriamae, by its smaller body size and the anatomy of the carpal and metacarpal regions, with relatively larger (sometimes fused) supernumerary carpal and metacarpal tubercles. Molecular phylogenetic analyses based on fragments of the mitochondrial genes 16S rRNA and COI suggest that the currently known distribution of the species is restricted to its type locality and other areas within Estação Ecológica Juami-Japurá, state of Amazonas, Brazil. Based on molecular, morphological and bioacoustic evidence, we assigned other specimens recently collected in Parque Nacional do Jaú, state of Amazonas, Brazil, to P. miriamae, extending the species’ known geographic distribution north of the Amazon River.

We present the description of Phrynus calypso sp. nov. from Trinidad and Tobago, and Venezuela This species is very similar to Phrynus pulchripes (Pocock), however after examining Colombian specimens of P. pulchripes (ca. type locality), many differences were found. Characters commonly used in diagnosis of Phrynus species are variable and make identification difficult. Differences in a few structures, like pedipalpal spines, could not be enough to provide a useful diagnosis.  It is necessary to account for variation of similar species in conjunction, and select non overlapping groups of characters. Observations in the variation in both species are presented, pointing out sources of confusion, and suggesting alternative characters to support diagnoses. At the moment, details about variation in many species in Phrynus, like that of P. pulchripes, are poorly known, and for this reason a redescription is provided.

Anopheles (Nyssorhynchus) deaneorum sp. n. is described from specimens collected in Guajará-Mirim, Rondônia state and Rio Branco, Acre state, Brazil, on human and animal baits, inside dwellings and from the progenies of engorged females. A detailed description of the shape of egg, external appearance of adult female and male, genitalias, female cibarial armature and complete chaetotaxy of pupa and larva show that it can be distinguished from Anopheles albitarsis from the type-locality and other areas by the paler general external appearance of the adult, the posterolateral tufts of scales, on the female abdominal terga and the branching of the outer anterior clypeal seta (3-C) of the fourth instar larva (as shown in illustrations). If species can also be distinguished from An. albitarsis from the type locality by the allele frequencies at 11 enzymic loci as represented by Nei's Genetic Distance.

Callogobius winterbottomi new species is described from the 33.8 mm SL holotype and two paratypes (32.2 mm SL and 22.9 mm SL) from the Comoros, Western Indian Ocean. It is distinguished from all other known Callogobius species by the following combination of characters: sensory pores absent, 23–26 scales in lateral series, and sensory papillae pre-opercular row not continuous with transverse opercular row. One additional specimen of Callogobius winterbottomi was located from South Africa. A new standardized naming system for Callogobius sensory papillae rows is presented for identification and clarification of character states among Callogobius species. The new species is tentatively placed among what we term the “sclateri group”, a clade including C. sclateri (Steindachner) and three other species that exhibit a modified female urogenital papilla with lateral distal flaps and elongate ctenii on the caudal peduncle scales. Callogobius tutuilae (Jordan & Seale) is removed from synonymy with C. sclateri because it has partially united pelvic fins (vs separate) and the preopercular sensory papillae row is continuous with the transverse opercular row (vs separate).
