Abstract

Abstract

We report a new species of the genus Micryletta from the montane evergreen forest in the Bidoup-Nui Ba National Park, Lam Dong Province, Langbian Plateau, southern Vietnam, based on molecular and morphological evidence. The new species is diagnosed by a combination of the following morphological characters: body size small (snout-vent length (SVL) 22.4 mm, single female); iris uniform black; snout nearly truncate in dorsal view, slightly rounded in profile; tibiotarsal articulation of adpressed limb reaching level of eye; dorsal surface smooth; supratympanic fold present, prominent; outer metatarsal tubercle absent; tips of toes very weakly dilated into small discs; finger webbing absent, toe webbing rudimentary; dorsal surfaces of head and body orange-red with small irregularly shaped dark-brown patches; dorsal surface of limbs pale dark brown with small reddish speckles; body flanks dark brown anteriorly fading to grayish brown posteriorly with brown spots in groin area; lateral sides of head immaculate blackish brown without white patches; coloration of ventral surfaces immaculate dark gray. The new species is divergent from all other congeners in 16S rRNA gene sequences (2.6%–5.8%). Following the IUCN Red List Categories and Criteria, we propose the new species be listed as Data Deficient (DD).
