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).
