Batasio tengana is redescribed on the basis of fresh material and a neotype designated. Two new species are described: Batasio fasciolatus n. sp. is described from material previously identified as B. tengana from the Brahmaputra River drainage and can be distinguished from congeners in having a combination of five to six vertical dark brown bars on a light brown body, dorsal-spine length 13·6–16·8% standard length (LS), pectoral-spine length 12·7–14·3%LS, and eye diameter 16·5–18·8% head length (LH). Batasio spilurus n. sp. is described from the Brahmaputra River drainage in Assam and can be distinguished from congeners in having a short adipose-fin base (12·6–12·8 v. 14·5–33·3%LS) and more slender caudal peduncle (5·7–6·2 v. 6·7–11·8%LS).
