Piscesilim (2) Fishes of Mainland Southeast Asia (1)

The species was described from the vicinity of Sukaranda, northern Sumatra (Volz 1904). Silurichthys leucopodus Fowler 1939, described from Trang in peninsular Thailand, is considered its junior synonym (Ng and Ng 1998). Habitat: The species is known from Wampu River drainage in northern Sumatra, river drainages that drain both the eastern and western coast of the northern Malay Peninsula, from the Perak and Besut river drainages northwards to the Isthmus of Kra, the short coastal rivers that drain the southern face of hills in southeastern Thailand and southwestern Cambodia (Ng and Ng 1998), and Phu Quoc Island in Vietnam (Vasil'eva and Vasil'ev 2012). Its Extent of occurrence (EOO) is estimated to be 396,170 km2, calculated from a minimum convex polygon using georeferenced data in Ng and Ng (1998) and GBIF (2019). Seems to inhabit fast-flowing mountain streams with a sandy or rocky bottom and can be found hiding under rocks. Remarks: Although there is no detailed information on the population status of this species, survey data indicates that it is still abundant in many parts of its known distribution and the population trend is thus suspected to be stable or declining at a rate that precludes it from a threatened category. While there may be localised or regional threats, they are unlikely to affect this species on a range-wide scale, and it is found within several protected areas. Therefore, it is assessed as Least Concern (IUCN 2019).
