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%.

A new species of frog, Eleutherodactylus geitonos sp. nov., is described from the southeastern slope of the Cordillera Central, Dominican Republic. The new frog is closely related to E. haitianus and both species share a small size. They differ in some morphological proportions and other external features, coloration, advertisement calls and DNA sequences of the 16S rRNA gene. Morphological and bioacoustic comparisons with other species in the  E. abbotti species group are also provided. Our preliminary genetic data suggest that the taxonomic status of E. neodreptus (a synonym of E. audanti) and E. melatrigonum need to be re-evaluated.

This study describes a new member of the genus Leptobrachella, Leptobrachella shangsiensis sp. nov., based on morphological, acoustic and molecular analyses from southern Guangxi, China. L. shangsiensis sp. nov. differs from its congeners by a combination of the following characters: (1) SVL 24.9–29.4 mm in 11 males and 30.8–35.9 mm in 5 females, (2) black supratympanic fold with dark reddish rim, (3) ventrolateral glands distinct, forming a broken line, (4) ventral surface yellowish creamy-white with marble texture, (5) iris copper in the upper and silver in the lower fifth and (6) toe webbing basal and narrow lateral fringes. The male advertisement call of L. shangsiensis sp. nov. consists of one note per call, lacking an introductory note, with a mean dominant frequency of 5.5–6.5 kHz at the ambient temperature of 21.5ºC. Uncorrected sequence divergences between L. shangsiensis sp. nov. and all homologous DNA sequences available for the 16S rRNA gene were found to be > 5.9%. L. shangsiensis sp. nov. occurs in an evergreen forest in Shiwandashan National Nature Reserve located at an elevation of 450–550 m.

In this article, a new species of salamander of the genus Bolitoglossa (Eladinea) from the cloud forest near La Mucuy in Sierra Nevada de Mérida, Venezuelan Andes, is described. Bolitoglossa mucuyensis sp. nov. differs from all Venezuelan salamanders, except B. orestes, by a larger SVL/TL ratio, and from La Culata salamander B. orestes by a reduced webbing extension of the front and hind limbs. Additionally, B. mucuyensis sp. nov. and B. orestes diverge 3.12% in terms of the nucleotide sequence of the 16S rRNA gene, as previously reported, and in 8.1% for the cytb gene as shown in this study.

A New Species

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.

The presented work summarises new and existing phenotypic and phylogenetic information for the genus Cruziohyla. Data based on morphology and skin peptide profiling supports the identification of a separate new species. Specimens of Cruziohyla calcarifer (Boulenger, 1902) occurring in Ecuador, Colombia, two localities in Panama, and one in the south east Atlantic lowlands of Costa Rica, distinctly differ from those occurring along the Atlantic versant of Central America from Panama northwards through Costa Rica, Nicaragua, to Honduras. A new species—Cruziohyla sylviae sp. n.—(the type locality: Alto Colorado in Costa Rica)—is diagnosed and described using an integrated approach from morphological and molecular data. Phylogenetic analysis of DNA sequences of the 16S rRNA gene confirms the new species having equal minimum 6.2% genetic divergence from both true C. calcarifer and Cruziohyla craspedopus.

A New Species

This study describes a new species of the genus Leptobrachella, Leptobrachella suiyangensissp. nov. from the Huoqiuba Nature Reserve, Suiyang County, Guizhou Province, China, based on morphological data and phylogenetic analyses (16S rRNA mtDNA). The new species can be distinguished from other congeners by the molecular divergence and by a combination of morphological characters, including body size, dorsal and ventral patterns, dorsal skin texture, size of the pectoral and femoral glands, degree of webbing and fringing on the toes and fingers, dorsum coloration, and iris coloration in life. Currently, the genus Leptobrachella contains 75 species, 21 of which are found in China, including seven species reported from Guizhou Province. The uncorrected sequence divergence percentage between Leptobrachella suiyangensissp. nov. and all homologous DNA sequences available for the 16S rRNA gene was found to be >4.7%. The new record of the species and its relationships with others in the same genus imply that species distribution, habitat variation, environmental adaptation, and diversity of the genus Leptobrachella in southwest China need to be further investigated.

Based on samples collected from the Yellow Sea in October 2014, a new species of pasiphaeid shrimp, Leptochela (Leptochela) tuerkayi sp. nov., is described. The new species is closely related to L. (L.) gracilis Stimpson, 1860 in morphology but differs from the latter and other congeners by the following combination of characters: three longitudinal dorsal carinae in ovigerous females, third maxilliped with the rather short exopod slightly overreaching the distal margin of the antepenultimate segment and the fourth pereiopod with the exopod reaching beyond the end of the merus. Morphological data and a partial sequence of the 16S rRNA gene of the new species are provided to show its systematic position.

A New Species

A new species of the microhylid frog genus Microhyla is described from the Fanjing Mountain of Guizhou Province, China. Phylogenetic analyses based on DNA sequences of the the mitochondrial 12S rRNA, 16S rRNA and COI genes supported the new species as an independent lineage, closely related to M. beilunensis, M. mixtura and M. okinavensis. The uncorrected genetic distance on 16S rRNA gene between the new species and its closest congeners M. beilunensis, M. mixtura and M. okinavensis are 3.5%, 4.6% and 4.6% respectively. The new species is distinguished from its congeners by a combination of the following morphological characters: (1) body of medium size (SVL 19.0–22.7 mm in males and 22.5–23.0 mm in females); (2) disk and dorsal median longitudinal groove on finger tips absent; (3) toe with rudimentary webbing at base; (4) disk with dorsal median longitudinal groove present at toe tips except for the toe I; (5) two metatarsal tubercles on palm; (6) tibiotarsal articulation reaching the level between eye to nostril when leg stretched forward; (7) a distinct V-shaped white stripe on the upper midsection. The new species is known only from the type locality, and thus the finding of it has contributed to the endemic species diversity of China. It is needed to take strategy to protect the species and habitats due to the increased threats of environmental changes.
