Range Description

This species is so far known only from northern Vietnam (Böhme et al., 2005). There are confirmed records from the following localities: the vicinity of Dong Vanh Village, Luc Son Commune, Luc Nam District, Bac Giang Province at 250-300m asl (21°12' N, 106°40' E) (Böhme et al., 2005); Quang Thanh Commune (22°38' N, 105°55' E) and Thank Cong Commune (22°48' N, 105°44' E), both of these being in Nguyen Binh District, Cao Bang Province (Böhme et al., 2005); Mau Son Mountain in Lang Son province at 900-1,000m asl (Nguyen Quang Truong pers. comm.); and Xuan Son National Park in Phu Tho Province (Nguyen Quang Truong pers. comm.). Records from and Pu Hoat Forest, Dong Van Commune, Que Phong District, Nghe An Province were attributed to Tylototriton vietnamensis (Böhme et al., 2005), but genetic studies have since shown that these belong to another species (Nguyen Quang Truong pers. comm.). Specimens from Nam Tha Commune (21°55' N, 104°22' E, 850m a.s.l.), in Van Ban District, Lao Cai Province and from Tay Con Linh Mountain (22°45’ N, 104°49’ E, 1,700m asl), in Vi Xuyen District, Ha Giang Province exhibit some slight morphological differences from T. vietnamensis (Böhme et al., 2005; Nguyen Quang Truong pers. comm.), and have been referred to as Tylototriton asperrimus (Bain and Nguyen, 2004), but might belong to an undescribed species (Nguyen Quang Truong pers. comm.). The species probably also occurs more widely, including in adjacent southern China (Böhme et al., 2005). Indeed, several Vietnamese records previously referred to as Tylototriton asperrimus (or Echinotriton asperrimus) are likely to refer to T. vietnamensis (Fleck, 2003; Nguyen, et al., 2005).
