- Аннотация: We report on a discovery of a new genus of microhylid subfamily Asterophryinae from northern and eastern Indochina, containing three new species. Vietnamophryne Gen. nov. are secretive miniaturized frogs (SVL < 21 mm) with assumingly mostly semi-fossorial life style. To assess its phylogenetic relationships we studied 12S rRNA-16S rRNA mtDNA fragment with final alignment comprising up to 2591 bp for 53 microhylid species. Characters of external morphology and osteological characteristics analyzed using microCT-scanning were used for description of the new genus. Results of phylogenetic analyses assign the new genus into the mainly Australasian subfamily Asterophryinae as a sister taxon to the genus Siamophryne from southern Indochina. The three specimens collected from Gia Lai Province in central Vietnam, Cao Bang Province in northern Vietnam and Chiang Rai Province in northern Thailand proved to be separate species, different both in morphology and molecules (genetic divergence 3.1% ≤ p ≤ 5.1%). Our work provides further evidence for the “out of Indo-Eurasia” scenario for Asterophryinae, and indicate that the Indochinese Peninsula was the area of initial cladogenesis and differentiation of this group of frogs. To date, each of the three new species of Vietnamophryne Gen. nov. is known only from a single specimen; their distribution, life history, and conservation status requires further studies.
