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.

A new species of the Asian leaf litter toad genus Leptobrachella is described from Guizhou Province, China. Molecular phylogenetic analyses support the new species as an independent lineage deeply nested in the Leptobrachella clade. The new species is distinguished from its congeners by a combination of the following morphological characters: body size medium (SVL 29.7–31.2 mm in five adult males); dorsal skin shagreened, some of the granules forming longitudinal short skin ridges; tympanum distinctly discernible, slightly concave; supra-axillary, femoral, pectoral and ventrolateral glands distinctly visible; absence of webbing and lateral fringes on fingers; toes with narrow lateral fringes but without webbing; heels overlapping when thighs are positioned at right angles to the body; tibia-tarsal articulation reaching the middle of eye when leg stretched forward. The discovery highlighted the underestimated species diversity in the Leptobrachella toads in southwestern China.

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 species of Selvasaura from the montane forests of the eastern slopes of the Andes in northern Peru, based on external and hemipenial morphological characters and previous phylogenetic analyses. The new species can be differentiated from the other two Selvasaura species in having keeled dorsal scales usually flanked by longitudinal striations, in adults and juveniles; adult males with a yellow vertebral stripe bordered by broad dark brown stripes on each side and a unilobed hemipenis surrounded by the branches of the sulcus spermaticus. The description of the new species contributes information about new states of diagnostic characters of Selvasaura and natural history.

A new species of Phrynobatrachus is described from the unexplored and isolated Bibita Mountain, southwestern Ethiopia, based on morphological characters and sequences of the mitochondrial rRNA16s. The new species can be distinguished from all its congeners by a small size (SVL = 16.8 ± 0.1 mm for males, 20.3 ± 0.9 mm for females), a slender body with long legs and elongated fingers and toes, a golden coloration, a completely hidden tympanum, and a marked canthus rostralis. The phylogenetic hypothesis based on 16s sequences places the new species as sister to the species group that includes P.natalensis, although it is morphologically more similar to other dwarf Phrynobatrachus species, such as the Ethiopian P.minutus.

A new species of the romaleid grasshopper genus Zoniopoda Stål (Romaleidae: Romaleini) is described and illustrated from the Sierras Chicas of Córdoba Province, central Argentina. A cladistic analysis based on morphological characters indicates that the genus Zoniopoda constitutes a monophyletic group and that Zoniopoda serrana n. sp. must be assigned to Iheringi species group based on synapomorphies of the pronotum and body color. The new species is similar to Z. similis Bruner from Paraguay, Bolivia and Brazil, from which it can be distinguished by the color pattern of the body, shape of the pronotal dorso-median carina and characters of the male terminalia and epiphallus. This paper has been formatted with embedded links to images of the type specimen, maps based on georeferenced specimen data for the genus and an updated key to the species of Zoniopoda available on the Orthoptera Species File (OSF) online (http://orthoptera.speciesfile.org).

A new species of deep water alpheid shrimp, Alpheus luiszapatai sp. nov., from Arusí, Chocó, Pacific coast of Colombia is described. The single female known was collected between the discarded bycatch of deep water shrimp trawls dedicated to the commercial fisheries of the “coliflor” shrimp Solenocera spp. This new species is placed putatively in the Alpheus brevirostris (Olivier, 1811) species group, and share some external morphological characters with Alpheus hephaestus Bracken-Grissom & Felder, 2014. It can be differentiated by the shape and ornamentation of major and minor chelipeds, the propodi and dactyli of third to fifth pereopods, the diaresis of uropodal exopod, the length of the rostral carina, color in life and bathymetric distribution. Additional comparison with another congeners pertaining to this species group complex from the eastern Pacific, western Atlantic and other oceanographic regions is discussed. A key for Alpheus brevirostris species group from the eastern Pacific is presented.

A new species, Sphaeropthalma nocticaro, is described from Oaxaca, Mexico and Petén, Guatemala. This species is placed into the S. pensylvanica species-group, with which it shares many morphological characters. This species-group is found predominately in the Southeastern USA ranging into eastern Texas, and addition of this new species greatly extends the geographic range of this group.

We describe a new Pristimantis from La Libertad and Rumiloma, Reserva Mazar, Andes of Southeastern Ecuador, at elevations between 2895–3415 m. This species is assigned to the P. orestes group, from whose members it differs by its small body size (adult males ≤ 18.1 mm; adult females ≤ 23.7 mm), usually reticulated ventral pattern, and visible tympanum. The vocalization of the new species consists of a series of calls; each call is composed by a pulsed, non-modulated note in frequency, and with a dominant frequency of 3122–3171 Hz. A molecular phylogeny based on a fragment of the mitochondrial gene 12S shows that the new species is sister to Pristimantis simonbolivari.

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%.
