A new species of frog of the genus Pristimantis is described from the paramos of the Nudo de Cajanuma, Podocarpus National Park, on the border between the provinces of Loja and Zamora-Chinchipe, Ecuador. The new species is readily distinguished from all other species of Pristimantis by its large body size (snout-vent length: 50.0–50.5 mm in adult females, 34.7–42.5 mm in adult males), thick glandular skin, large warts on flanks, prominent glandular patches on head and legs, and dark brown dorsum. This new species is among the largest and stoutest Pristimantis frogs of the high Andes. It is only known from its type locality, where it occurs in paramo bambusoid meadows at elevations between 3300 and 3400 m. It is morphologically similar to Pristimantiserythros, P.farisorum, P.obmutescens, P.orcesi, P.racemus, P.simoterus, P.simoteriscus, and P.thymelensis. Notorious morphological characters present in this new species are thick glandular patches covering dorsum and limbs and porous skin texture, which are shared with P.erythros.

We describe a new, medium-sized Leptolalax species from Vietnam. Leptolalax petrops sp. nov. is distinguished from its congeners by a combination of having a medium-sized body (23.6–27.6 mm in 21 adult males, 30.3–47.0 mm in 17 adult females), immaculate white chest and belly, no distinct black markings on the head, highly tuberculate skin texture, toes lacking webbing and with narrow lateral fringes, and a call consisting of an average of four notes and a dominant frequency of 5.6–6.4 kHz (at 24.5–25.3 °C). Uncorrected sequence divergences between L. petrops sp. nov. and all homologous DNA sequences available for the 16S rRNA gene are >8%.

We describe a new species of fan-throated lizard of the genus Sitana from the Deccan peninsula of India. The new species is from the Sitana sivalensis clade and can be readily diagnosed morphologically from S. sivalensis, S. fusca and S. schleichi by having the dewlap extending beyond forearm insertion. The new species differs from all other congeners in the combination of morphological characters such as a feebly serrated dewlap with a dark blue line on the throat in adult males (versus  a well serrated dewlap with a bright blue patch and orange spots in S. ponticeriana complex), small body size (versus a large body size in S. gokakensis and S. thondalu) and a relatively smaller dewlap size (relatively larger in S. laticeps, S. spinaecephalus, S. dharwarensis, S. gokakensis, S. thondalu, S. marudhamneydhal, S. ponticeriana and S. visiri). The new species was found to be commonly distributed in arid and open habitats as well as in farmlands and plantations in northern Andhra Pradesh, eastern Madhya Pradesh and most parts of Chhattisgarh and Odisha states.

The northernmost Peruvian Andes, a unique biogeographic region characterized by the confluence of multiple distinct ecosystems (i.e. Amazon basin, Pacific rainforest, the Sechura Desert, the northern and central Andes), is the southernmost geographic range limit of the South American shrews representing the genus Cryptotis. In the northernmost Peruvian Andes, two poorly known species have traditionally been reported (C. peruviensis and C. equatoris). Our study, based on molecular and morphologic traits, confirms the presence of C. peruviensis but also the occurrence of C. montivaga, based on specimens erroneously assigned to C. equatoris. Moreover, a new species of Cryptotis from the páramo and montane forests of the Tabaconas Namballe National Sanctuary near the Ecuadorian border is also described. It is a member of the thomasi group and is distinguished from other South American shrews by a unique set of morphological characters, including large body size, comparatively short tail, simple ectoloph of M3, and large PM4 post protocrista.

The small nurse frogs of the genus Allobates (Anura, Aromobatidae) represent one of the most challenging taxonomic issues of the Neotropics. During several amphibian surveys in the Middle Tapajós River region, state of Pará, Brazil, we collected phenotypic, ecological, and molecular data on species of this genus, leading to the identification of a new species included in the Allobates masniger-nidicola complex. The new species is characterized by a large body size (snout-vent length 19.2–21.7 mm in males and 19.3–22.0 mm in females), finger III not swollen in adult males; cryptic external coloration, with dorsum uniformly ochre; a dark brown lateral stripe and a pale cream ventrolateral stripe; limbs ranging from ochre to orange; throat and chest violaceous in males and yellowish in females. The advertisement call is usually arranged in bouts of four closely spaced notes, which we term 4-pulsed units of repetition (UR), 0.317 s long on average, followed by silent intervals, and an average dominant frequency of 4.163 kHz. The new species also has exotrophic tadpoles with a unique fin morphology, which begins after the body-tail insertion and is deeper posteriorly to half of the caudal length. Sequencing of the 16S and COI regions of the mitochondrial DNA show a genetic p-distance of approximately 6–10% compared to closely related congeners. We discuss the biogeography of the new species based on phylogenetic relationships of the species within the Allobates masniger-nidicola complex and the allopatric geographic distribution in relation to sister taxa. Functional characteristics and geographic restrictions make this species particularly sensitive to the increasing human impact in eastern Amazonia.

A new genus and species of Asian green pitviper is described from Southwest China based on two female specimens. A new DNA phylogeny recovers the two specimens of the new species as a well-supported clade that is sister group to all sampled representatives of the genera Viridovipera and Cryptelytrops. The new genus is distinguished from other pitviper genera by a combination of morphological characters, including the absence of a lateral stripe, large body size, and deep red eye in adult females. Morphologically the new species is superficially most similar to species of Popeia in body dimension and scalation, but is genetically extremely distinct. The new genus/species is currently known only from south Sichuan, where it was found at about 1000 m above sea level in less disturbed evergreen rainforest.

We describe a new species of terrestrial limestone forest frog of the genus Platymantis from Biak Na Bato National Park in central Luzon Island, Philippines. Platymantis biak is assigned to the primarily arboreal Platymantis guentheri Species Group, and is distinguished from these and other congeners by features of its external morphology and preferred terrestrial limestone microhabitat. Several distinguishing morphological characters include a moderately large body (32.3–39.9 mm SVL for 23 males and 37.4–42.4 mm SVL for 8 females), moderately expanded finger discs and slightly expanded toe discs, smooth skin, and limb banding pattern. The new species is yet another species in a rapidly growing group of newly discovered Philippine forest frogs with preferences for forested, karst habitats.

Aplectana longa n. sp. (Ascaridida: Cosmocercidae) from the small intestine of Gastrotheca microdiscus (Amphibia: Hemiphractidae) is described and illustrated. The new species is characterized by the combination of a unique set of morphological characters: 1) Large body size in both sexes; 2) Lateral alae absent; 3) Gubernaculum present, small, thin, weakly sclerotized, pointed at the distal end and curved proximally at the end, with a small and punctiform papilla-like dilation, and 4) Caudal papillae arrangement (9+1:0:6). The distribution pattern of caudal papillae is similar only to Aplectana chamaeleonsis. Nevertheless, Aplectana longa n. sp. is easily differentiated from this species by the arrangement of precloacal papillae. This is the 57th species of the Aplectana and the 16th species reported from Brazil.

Rana jiulingensissp. nov., a new species from Hunan and Jiangxi, southeastern China, is described. The new species is assigned to the R. japonica group. The clade comprising R. jiulingensissp. nov. and R. dabieshanensis from Anhui is the sister taxon of R. omeimontis from Sichuan. Rana jiulingensissp. nov. can be distinguished by the significant divergences in the 16S and COI genes, and the combination of following morphological characters: body size medium, SVL 48.3–57.8 mm in adult males and 48.2–57.5 mm in adult females; dorsolateral fold straight; digits without circummarginal grooves; dorsal skin smooth; tibio-tarsal articulation reaching forward beyond the tip of snout; heels overlapping; webbing formula of toes: I 1⅓ – 2 II 1⅓ – 2⅓ III 1½ – 2⅔ IV 3 – 1⅓ V; absence of vocal sacs in males; and presence of creamy white nuptial pad with tiny hoar spines on the finger I and reddish tubercles on loreal and temporal regions in breeding males. Furthermore, based on our results and the previous literature, R. zhengi is synonymized with R. sangzhiensis, and a new species group, the Rana johnsi group, is proposed for the R. johnsi and R. sangzhiensis. Currently, the Rana contains 41 recognized species, and the phylogenetic placements of several species remain unresolved.

The oribatid mite subgenus Scheloribates (Topobates) Grandjean, 1958, is recorded from the Neotropical region for the first time. A new species of this subgenus is described from the leaf litter collected in Cayo Agua Island, Panama. Scheloribates (Topobates) panamaensis sp. nov. differs from its related species by the very large body size and presence of a strong ventrodistal process on the leg femora II–IV.
