Sinonatrix aequifasciata is listed as Least Concern in view of its wide distribution, tolerance of human-affected environments, and the lack of any major widespread threat acting upon it.
|Range Description:||This species is distributed from southern China, including Hong Kong and Hainan and west to the province of Guizhou (Zhao and Adler 1993), through Viet Nam (Orlov et al. 2000) to the Annamite Mountains in central Lao PDR (Stuart 1999). In Viet Nam it has been recorded from Cao Bang (Nguyen Binh), Lao Cai (Van Ban), Vinh Phuc (Tam Dao), Bac Giang (Luc Son), Ha Tinh (Rao An) (Vogel et al., 2004; Nguyen et al., 2009) The elevation range of this species is 100 to 2,000 m above sea level (Zhao et al. 1998, M. Lau pers. comm. 2008).|
Native:China (Chongqing, Fujian, Guangdong, Guangxi, Guizhou, Hainan, Hunan, Jiangxi, Sichuan, Zhejiang); Hong Kong; Lao People's Democratic Republic; Viet Nam

|Population:||It is a common species.|
|Habitat and Ecology:||This species is found in streams and waterways in or near forests, including ditches bordering agricultural land (Bain and Truong 2004, Orlov et al. 2000, Stuart 1999). It is oviparous and is active both at day and at night.|
|Major Threat(s):||Some deforestation is occurring in this region, due to logging, infrastructure development and the expansion of agriculture. It is likely that this species is experiencing habitat loss and degradation in portions of its range. However, due to its apparent tolerance, to a certain extent, of human-impacted environments and its large range, these should not be considered major threats at this time.|
|Conservation Actions:||There are no known species-specific conservation measures in place for this species, however, in places its distribution coincides with protected areas.|
