A New Species

Substantial molecular and morphological character differences lead us to the description of a new species of the genus Pristimantis from the cloud forest of Cerro Chucantí, Maje Mountains, Darien Province, as well as from several other mountain ranges in eastern and central Panama. Pristimantis gretathunbergaesp. nov. is a sister species to the allopatric P. erythropleura-penelopus group from northern Colombia with a mtDNA sequence divergence of > 4.4% at 16S and > 14.6% at COI. Its closest congener in sympatry is P. cruentus that differs by a large sequence divergence of > 9.6% in 16S mtDNA and 19.0% at COI, and from which it differs also by ventral and groin coloration, unusually prominent black eyes, a contrasting light upper lip, commonly a single conical to spine-like tubercle on the upper eyelid, and a larger head. While the habitat continuity at most sites in eastern Panama is moderate, habitats in central Panama are severely fragmented. Cerro Chucantí and the surrounding Maje Mountains are highly threatened by rapid deforestation and replaced by plantations and cattle pastures. Thus, investigations on the ecology of the new species and its population status, especially at the type locality, are highly recommended. As a flagship species, this new frog can help to preserve the Chucantí cloud forest including several recently described species known only from this isolated area in eastern Panama.

A New Species

A new species of African reed frog (genus Hyperolius Rapp, 1842) is described from the Coastal Forests of the Eastern Africa Biodiversity Hotspot in northeastern Mozambique. It is currently only known from less than ten localities associated with the Mozambican coastal pans system, but may also occur in the southeastern corner of Tanzania. Phylogenetic reconstructions using the mitochondrial 16S marker revealed that it is the sister taxon of Hyperolius mitchelli (>5.6% 16S mtDNA sequence divergence) and forms part of a larger H. mitchelli complex with H. mitchelli and H. rubrovermiculatus. The new species is distinguished from other closely related Hyperolius species by genetic divergence, morphology, vocalisation, and dorsal colouration.

A New Species

A new frog species of the genus Diasporus is described from Llano Tugrí, Corregimiento de Peña Blanca, Distrito de Müna,Comarca Ngöbe-Buglé, Serranía de Tabasará, west-central Panama, around 1700 m a.s.l. The new species differs from all othermembers of the genus by a combination of morphological characters, in particular, its large size, its dorsal skin texture and itsbright coloration. This species is the largest species in the genus Diasporus; it is an inhabitant of cloud forest, living amongmosses and bromeliads. All specimens were found between the understory (≈ 1–2 m) and the mid-canopy (≈ 2–10 m). The callof this species consists of single, short notes that are reminiscent of a “whistle” and range from 2.0 to 2.7 kHz. Herein we pres-ent, besides morphological data used to describe the new species, the description of the male mating call, a distribution map, and brief ecological notes.

v This paper describes Elops smithi, n. sp., and designates a lectotype for E. saurus. These two species can be separated from the five other species of Elops by a combination of vertebrae and gillraker counts. Morphologically, they can be distinguished from each other only by myomere (larvae) or vertebrae (adults) counts. Elops smithi has 73–80 centra (total number of vertebrae), usually with 75–78 centra; E. saurus has 79–87 centra, usually with 81–85 centra. No other morphological character is known to separate E. smithi and E. saurus, but the sequence divergence in mtDNA cytochrome b (d = 0.023–0.029) between E. smithi and E. saurus is similar to or greater than that measured between recognized species of Elops in different ocean basins. Both species occur in the western Atlantic Ocean, principally allopatrically but with areas of sympatry, probably via larval dispersal of E. smithi by oceanographic currents.

We here describe Sitana attenboroughii sp. nov., a new species of fan-throated lizard of the genus Sitana Cuvier, 1829 from coastal Kerala in southern India. The new species morphologically is closer to Sitana visiri Deepak, 2016 (in Deepak et al. 2016a), however, differs in having higher numbers of ventral scales and a comparatively short but richly colored dewlap. Genetically the new species shows affinity to Sitana marudhamneydhal Deepak, Khandekar, Varma & Chaitanya, 2016 from which it differs in an uncorrected pairwise sequence divergence of 2.2% for a fragment of mitochondrial Nicotinamide adenine dinucleotide dehydrogenase (NADH) subunit 2 gene.

A New Species

A new species of Gracixalus is described from northwestern Vietnam based on morphological differences and molecular divergence. Morphologically, the new species, Gracixalus ziegleri sp. nov., is distinguishable from its congeners on the basis of a combination of the following diagnostic characters: (1) size small (SVL 28.1 – 30.5 mm); (2) head slightly wider than long; (3) vomerine teeth absent; (4) upper eyelid and dorsum without spine; (5) supratympanic fold distinct; (6) skin of dorsal and lateral surface of head, body and limbs rough, sparsely scattered with tubercles; (7) ventral skin granular; (8) tibiotarsal projection absent; (9) toes with moderately developed webbing, formula I1 – 11/2 II1 – 2III1 – 2IV2 – 1V; (10) dorsal surface of head and body brown to beige above, with an inverse Y-shaped dark brown marking, extending from interorbital region to central region of dorsum; (11) external vocal sac absent in males; (12) males with a nuptial pad on finger I. Phylogeneticially, the new species is a sister taxon of Gracixalus sapaensis and G. tianlinensis with well-supported values. Currently, the new species is known only from the evergreen montane tropical forest of Yen Bai Province at an elevation of ca. 2200 m a.s.l.

A New Species

We describe a new species of Zhangixalus from southern Yunnan of China, Vietnam, and Thailand based on morphological and molecular evidence. The new species had been confused with Zhangixalus smaragdinus (Blyth, 1852) in the past. Zhangixalus pachyproctus sp. nov. can be distinguished from Z. smaragdinus morphologically by the protruding vent in adult males, large thick grey reticular mottles below the white stripe on flank, more oblique snout in profile and wider head, longer snout, greater internarial distance, larger tympanum and longer hindlimb. The new species can be distinguished from other species of Zhangixalus with green dorsum by the following combination of characters: body size larger (SVL of adult males: 74.2–83.3 mm; SVL of adult female: 102.4 mm); dorsum smooth; narrow white stripes along edge of the lower jaw, body sides, outer side of limbs and above the vent; absence of brown bands on canthus rostralis, upper eyelid and supratympanic fold; webbing between fingers and toes complete except between the first two fingers; and internal single subgular vocal sac. Phylogeny based on comparison of 16S rRNA sequences suggests that the new species is the sister taxon to Z. smaragdinus and the two species differ by 7.63% in the uncorrected pairwise distance of 16S sequences.

We present the results of herpetological surveys in two adjacent mountains where the EcoMinga Foundation protects the cloud forest in the Upper Rio Pastaza watershed, in the Llanganates Sangay Ecological Corridor in Ecuador. A rapid assessment of the amphibian communities of the study sites reveals a diverse and heterogeneous composition, dominated by terrestrial frogs from the genus Pristimantis. We also identify a cryptic diversity with a significant number of candidate new species. We describe two new species of terrestrial frogs of the genus Pristimantis. Pristimantis maryanneaesp. nov. is characterised by not having tympanum externally visible and having 2–3 subconical tubercles in the upper eyelid; and Pristimantis burtoniorumsp. nov. is characterised by the presence of red colouration in hidden surfaces of the hind-limbs, tubercles on the upper eyelid, interorbital tubercle and a row of rounded tubercles along the snout to the tip and a pale red venter with dark brown mottled pattern. Our samples from the two Reserves do not share species between them, so the proportion of shared species seems to be relatively low. In addition, we highlight the importance of updating the knowledge of amphibians that are restricted to this important conservation region and comment about the threats and composition of the amphibian communities on the eastern slopes of the Upper Rio Pastaza watershed.

Magnolia guerrerensis from the cloud forest in the state of Guerrero, Mexico, is illustrated and proposed as a new species. This taxon is similar to M. schiedeana Schltdl., but differs from it because of its smaller stipules, pedicellated flowers and gynoecium with less carpels. A key to distinguish both species is included.

A New Species

The first integrative taxonomic analysis of the Cyrtodactylus brevipalmatus group of Southeast Asia recovered two newly discovered populations from the Tenasserim Mountains in Suan Phueng District, Ratchaburi Province, Thailand as a new species described here as C. rukhadeva sp. nov. Based on 1397 base pairs of the mitochondrial gene NADH dehydrogenase subunit 2 (ND2), C. rukhadeva sp. nov. is the well-supported sister species to a clade containing three undescribed species, C. ngati, and C. cf. interdigitalis with a large uncorrected pairwise sequence divergence from other species in the brevipalmatus group ranging from 15.4–22.1%. Cyrtodactylus elok and C. brevipalmatus are recovered as poorly supported sister species and the well-supported sister lineage to the remainder of the brevipalmatus group. Cyrtodactylus rukhadeva sp. nov. is putatively diagnosable on the basis of a number of meristic characters and easily separated from the remaining species of the brevipalmatus group by a number of discrete morphological characters as well as its statistically significant wide separation in multivariate morphospace. The discovery of C. rukhadeva sp. nov. continues to underscore the unrealized herpetological diversity in the upland forests of the Tenasserim Mountains and that additional field work will undoubtedly result in the discovery of additional new species.
