The bagrid catfish Batasio merianiensis was described from only the holotype collected in the Brahmaputra River drainage, Assam, northeastern India. This poorly known catfish is rediagnosed and redescribed on the basis of fresh material in this study. Batasio merianiensis is diagnosed from congeners in having a combination of the following characters: length of adipose-fin base 16.9-22.2 % SL, dorsal fin when appressed not reaching anterior origin of adipose fin, body depth at anus 15.2-18.4% SL, caudal peduncle depth 9.7-11.5% SL, eye diameter 18.3-25.9% HL, vertical dark brown bars on head and body, and absence of dark mid-dorsal stripe.
