Pseudolaguvia Misra, 1976 : 253. Type species: Glyptothorax tuberculatus Prashad & Mukerji, 1929 , by original designation. Gender feminine.

Diagnosis (based, in part, on Ng 2005d): Short thoracic adhesive apparatus with median depression; wide gill openings nearly meeting one another on venter; serrations on anterior margin of pectoral spine pointing toward tip; smooth to granulate anterior margin on dorsal spine; slender body; papillate upper lip; 8-10 anal rays.

Pseudolaguvia is diagnosed from all other erethistids by having a thoracic adhesive apparatus with a median depression (vs. lacking a thoracic adhesive apparatus or having an apparatus without a median depression) and from all other erethistids except Caelatoglanis by having wide gill openings that nearly meet one another on the venter. Pseudolaguvia is further distinguished from Conta by having a smooth or granulate (vs. serrated) anterior margin on the dorsal-fin spine, from Caelatoglanis by having a papillate (vs. plicate) upper lip and a more slender body (Fig. 8), from Ayarnangra by having 8-10 (vs. 13-16) anal rays, from Erethistes by having a more slender body, and from Erethistoides by having the serrations on the anterior margin of the pectoral spine all directed toward the tip of the spine (vs. directed toward the tip of the spine distally and away from the tip proximally).

Description: Dorsal fin with strong spine, 5-6 rays; pectoral fin with strong spine, 6-8 rays; 6-10 pelvic-fin rays, 8-10 anal-fin rays. Head and body slightly depressed; body elongate (Fig. 8). Skin tuberculate. Eyes small, dorsal, in middle of head. Jaw teeth villiform, in bands; palatal teeth absent. Maxillary barbel usually shorter than head, with well-developed membrane, soft base. Barbels annulated with black rings. Gill openings wide, almost meeting each other on venter. Pectoral girdle with long coracoid process. Pectoral-fin spine serrated anteriorly and posteriorly. Dorsal spine smooth or granulate anteriorly, smooth or serrated posteriorly. Thoracic adhesive apparatus present, but may be poorly developed. Paired fins non-plaited.

Distribution: Ganges and Brahmaputra drainages, India, Nepal and Bangladesh, east and south to the Sittang drainage, Myanmar (Jayaram, 1999; Britz & Ferraris, 2003; Ng, 2005d).
