This species is known from eastern Myanmar, most of Thailand (Taylor, 1962; Chan-ard et al., 1999), several localities from Lao People's Democratic Republic (Stuart, 1999), northern and central Viet Nam (Inger et al., 1999; Lathrop et al, 1999b; Orlov et al., 2000), Mengyang in Jinghong County in southern Yunnan, China, and is localized in Peninsular Malaysia (Berry, 1975). It is known from 200-1,900m asl.
Habitat and Ecology
It inhabits streams and streamside evergreen forest. Tadpoles inhabit clear swift-flowing sand gravel streams.
It is a small cryptic species but is generally fairly common and sometimes very common in suitable localities.
Degradation of forest and streams through agricultural and other developments are threats to this species.
It occurs in a number of protected areas in Thailand and elsewhere, and its survival should be secure as long as these protected areas remain intact. In China it occurs in the Xishuangbanna National Nature Reserve. Further taxonomic studies would be desirable, as would information on distribution, population status and natural history of the various forms.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
A number of different forms are currently included in Leptolalax pelodytoides that might prove to be taxonomically recognizable.
