Range Description

This species is currently known from 284-511m asl in the Sangi River drainage basin, Vilabouli District, Savannakhet Province, Lao People's Democratic Republic (Rowley et al. 2010), and Ha Tinh, Nghe An and Quang Binh Provinces, Viet Nam (Ohler et al. 2011). More information on the actual distribution of the species would likely result from more extensive surveys as well as taxonomic reassessments of existing specimens (B. Stuart pers. comm., February 2014). The combined known and inferred localities of this species represent an extent of occurrence of 53,002 km², which consists of three separate threat-defined locations.

Habitat and Ecology

This species inhabits rocky streams and adjacent areas in evergreen and semi-evergreen forest, which is significantly disturbed in some parts of its range. Males have been observed calling from atop rocks, in crevices, and on stream banks in both June and November, and reproduction may occur throughout the year (Rowley et al. 2010). Eggs and larvae of this species are unknown, however it likely has a free-swimming larval stage like all other Leptolalax species for which larvae are known (J. Rowley pers. comm. February 2015).


This species has been observed in abundance at the type locality (Rowley et al. 2010), however its relative abundance is unknown and further surveys in the area may help determine this. Due to ongoing local habitat loss, the species' population is thought to be decreasing.

Population Trend


Major Threats

One of the known localities of this species, in Vilabouli District, includes the Sepon Mining Tenement.  The species is currently surviving in some degraded habitat at that site, however further degradation - specifically the removal of evergreen or semi-evergreen riparian vegetation - may threaten the species at that locality (Rowley et al. 2010). Although the species appears to require closed evergreen or semi-evergreen forest along streams where it occurs, several of the streams documented run through quite degraded habitats. Populations may be able to persist for some time in modified habitats where riparian evergreen vegetation is retained (Rowley et al. 2010). In general, loss of forest habitat is ongoing throughout the region, which seems to constitute a threat to the species based on its ecological requirements.

Conservation Actions

The species has been reported from several protected areas, including Phong Nha-Ke Bang National Park, Pu Huong Nature Reserve, and Ky Anh-Ke Go Reserve in Vietnam (Ohler et al. 2011).

Red List Status

Least Concern (LC)


This species is listed as Least Concern as this species is relatively abundant throughout its inferred range of 53,002 km² and appears to be able to persist in some disturbed environments, but it is thought to occur in three threat-defined locations and there is ongoing habitat loss in the forests of Southeast Asia.
