Geographic Range [top]
Range Description: This species has been reported from northern Thailand, northern Viet Nam, Myanmar and the Chinese province Yunnan (Zhou and Adler 1993, Cox 1991). Recent surveys have been unable to confirm its occurrence in Myanmar, although the type locality, Toungyi, is in this country and the area has been surveyed recently (G. Zug pers. comm. 2009, G. Wogan pers. comm. September 2011). In Viet Nam it has been recorded from Muong Te in Lai Chan Province, Sa Pa in Lao Cai Province, Tu Ly in Hoa Binh Province, and Ky Son in Nghe An Province (Orlov et al. 2003, Nguyen et al. 2009).

Habitat and Ecology [top]
Habitat and Ecology: This species occurs in wet montane forest between 200 and 1,000 m asl. It is presumably oviparous and nocturnal, and probably feeds on worms, in common with other species of Plagiopholis.
Systems: Terrestrial
Use and Trade [top]
Use and Trade: There are no reports of this species being utilized.
Threats [top]
Major Threat(s): Forests in Thailand have experienced deforestation due to logging, both legal and illegal, and agricultural expansion. Between 1976 and 1989, forest cover declined by 28% (Cropper et al. 1999) in Thailand. Likewise, in Myanmar, the forests are under pressure and declined by 3% annually during the 1990s (Leimgruber 2005). The building of roads in this region may also contribute to the fragmentation of this species habitat. However, it is not known whether this species is being impacted as it is naturally rare and difficult to collect.
Conservation Actions [top]
Conservation Actions: There are no known species-specific conservation measures in place, although there are protected areas within its range in Thailand. Further research on its population trends, distribution and ecology is needed.
