Range DescriptionThe species is widely distributed in mainland Southeast Asia in medium and large rivers (Rainboth 1996). Known from the Mae Khlong and Chao Phraya in Thailand to the Mekong, the northern Malay Peninsular, and possibly the Dong Nai basin in Viet Nam (Doi 1997). A specimen probably referring to this species is reported from the Song Lagna in southern Viet Nam (W. Rainboth pers. comm. 2011). In the Mekong, it is found as far upstream as the Buyuan River in the Upper Mekong (Yunnan, southern China), which is an important feeding and spawning site (Kang et al. 2009). Recorded from numerous tributaries of the Mekong (e.g., the Xe Bang Fai and Nam Theun in Lao PDR; Nam Theun 2 Power Company 2005).
