TABLE 5. A morphological comparison of species of the genus Achalinus according to Van Denburgh (1912), Pope (1935), Bourret (1935, 1937), Smith (1943), Koshikawa (1982), Karsen et al. (1986), Ota & Toyama (1989), Zhao (2006), and Das (2010), Ziegler et al. (2019), Wang et al. (2019). Int. fus.: internasal fused to prefrontal; Intern. sut. = internasal suture; m = male; f = female; s+k = smooth on anterior, keeled on posterior body; s+k+k = keeled on mid and posterior body. “*” = according to Zhao (2006), and Zong et al. (1983), but given as smooth in Ota & Toyama (1989).
