Geographic Range [top]
Range Description: This snake is known only from Viet Nam, where it has been recorded from Yen Bai, Lao Cai, Quang Tri and Quang Nam Provinces (Nguyen et al. 2009). It is suspected to occur in adjacent areas of Lao PDR, but has never been recorded there (B. Stuart and Q.T. Nguyen pers. comm. 2011). The snakes extent of occurrence, based on the combined area of known sites, is approximately 18,000 km2. It has been found from 400 - 700 m asl.

Habitat and Ecology [top]
Habitat and Ecology: This is a terrestrial, oviparous snake of mountain regions, which has only been found in or near streams in secondary or primary evergreen forest. It is nocturnal and secretive.
Systems: Terrestrial; Freshwater
Continuing decline in area, extent and/or quality of habitat: Yes
Use and Trade [top]
Use and Trade: It is not known whether there is any use or trade in this species.
Threats [top]
Major Threat(s): This snake is known from a heavily-modified area in the Red River Valley in the north of the snakes range, which has a long history of human habitation and habitat modification. It is unclear whether it is threatened in central Viet Nam, as the forest in this area is protected. If it occurs in adjacent areas of Lao PDR, the snake may be able to persist in the extensive areas of remaining forest in this region (B. Stuart and Q.T. Nguyen pers. comm. 2011). However, road-building and encroachment of slash-and-burn agriculture into forested areas may still pose a threat to this species in these areas (Q.T. Nguyen pers. comm.2011). While this very rare snake has never been reported in trade, other species of Krait are exploited for use in rice wine and for traditional Chinese medicine, and this might also represent a risk to this snake.
Conservation Actions [top]
Conservation Actions: No conservation actions are in place for this species. Its range in central Viet Nam coincides with protected areas. Surveys are needed to locate additional records of this species, to obtain more information on its distribution, population status and exposure to threats.
