A New Species

We describe a new species ofPristimantisfrom the montane forest of the Río Zuñag Ecological Reserve, upper basin of the Pastaza River, Ecuador.Pristimantismalliisp. n.is characterized by a snout-vent length of 11.6–21.3 mm in adult males (n= 12), 22.6–34.3 mm in adult females (n= 8), and is compared morphologically and genetically withPristimantismiktosand with other relevant species ofPristimantis. The new species is characterized by having skin on dorsum and flanks shagreen, distinctive scapular folds, snout broadly rounded in dorsal view, upper eyelid bearing one or two subconical tubercles and some rounded tubercles, dorsum and flanks light brown to brown, with irregular dark brown marks bounded by dirty cream and groin with irregular yellowish marks.

A New Species

We describe a new species of bromeliad-dwelling Pristimantis from primary montane forest (2,225 m a.s.l.) in southern Peru. The type locality is near Thiuni, in the Department of Puno (province of Carabaya) in the upper watershed of a tributary of the Inambari River. Pristimantis achupalla sp. n. is characterized by a snout-vent length of 10.0–12.8 mm in adult males (n = 4), unknown in adult females, and is compared morphologically and genetically with species in the Pristimantis lacrimosus group, and with other similar species of Pristimantis. The new species is characterized by having skin on dorsum and flanks rugose, green brownish color, distinctive scapular folds, subacuminate or acuminate snout profile, upper eyelid bearing two or three subconical tubercles and some rounded tubercles, rostral papilla, flanks light brown to brown, with irregular dark brown marks.

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.

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.

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

A new species of tree frog, G. guangdongensis sp nov., is described based on a series of specimens collected from Dawuling Forest Station, Mount Nankun and Nanling Nature Reserve of Guangdong Province, southeastern China. The new species is distinguished from all known congeners by a significant genetic divergence at the mitochondrial 16S rRNA gene fragment examined (p-distance ≥ 4.6%) and the following combination of morphological characters: relatively small body size (SVL 26.1–34.7 mm in adult males, 34.9–35.4 mm in adult females); upper eyelid and dorsum lacking spines; supratympanic fold and tympanum distinct; dorsal and lateral surface rough, sparsely scattered with tubercles; ventral skin granular; tibiotarsal projection absent; toe-webbing moderately developed, finger webbing rudimentary; heels slightly overlapping when flexed hindlimbs are held at right angles to the body axis; brown to beige above, with an inverse Y-shaped dark brown marking extendeing from the interorbital region to the centre of the dorsum; males with a single subgular vocal sac and protruding nuptial pads with minute granules on the dorsal surface of the base of first finger. The discovery and description of Gracixalus guangdongensis sp. nov. represents the 14th species known in this genus.

A new frog of the genus Pristimantis is described from a montane cloud forest at 9 de Octubre (2°14’52” S, 78°16’37” W; 1778 m) province of Morona Santiago in the upper basin of the Upano River, southeastern Ecuador. The description of the new species is based on the examination of eleven adult males and three adult females. The new taxon can be readily distinguished from other congeneric species that inhabit the eastern Andes of Ecuador by the unique combination of the following characters: small body (adult males SVL 12.0–17.0 mm, adult females SVL 18.5–21.7 mm); skin of dorsum finely shagreen with two subconical scapular tubercles, weak and discontinuous dorsolateral folds in the middle of the back; large tympanum 70–93% of eye diameter; snout subacuminate in dorsal view, rounded in profile; upper eyelid bearing four or five small and flat supraocular tubercles; males lacking vocal slits and nuptial pads; all discs on fingers and toes lanceolate. Additionally, we provide information on the advertisement call and natural history of the new species.

We describe a new species of megophryid frog in the genus Leptolalax from southern Laos. Leptolalax aereus sp. nov. is distinguished from its congeners by a combination of size (25.1–28.9 mm in 28 adult males, 27.1–38.6 mm in 12 adult females), absence of distinct black or dark brown dorsolateral markings on head, near immaculate white chest and belly, head length greater than head width, no webbing or lateral fringing on fingers, rudimentary webbing between toes I–IV and no webbing between toes IV–V, toes with weak lateral fringing, and a call consisting of an average of 3–4 notes containing 1–2 pulses, and with a dominant frequency of 6187.5–7875 Hz. The new species is associated with rocky streams in semi-evergreen and evergreen forest between 284–511 m elevation.

Schistura rebuw, new species, is described from the Kameng River, a north-bank tributary of the Brahmaputra, Arunachal Pradesh, India. The new species is easily distinguished from all known congeners in the Brahmaputra basin by its unique sexual dimorphism, specifically a suborbital slit in adult females, and a suborbital flap in adult males; and a colour pattern of 10–11 blackish bars on a greyish-beige body, the pre-dorsal bars mostly broken or incomplete, coalescing dorsally in a more or less alternate fashion.
