Parachiloglanis Wu, He & Chu, 1981  ZBK  : 76, 79. (Type species Glyptosternum hodgarti Hora, 1923  ZBK  , by original designation). Gender masculine.

Diagnosis: No post-labial groove, lower lip continuous with isthmus without demarcation; gill openings not extending onto venter; homodont dentition; pointed teeth in both jaws; tooth patches joined into a crescent-shaped band in upper jaw; 13-16 branched pectoral rays.

Parachiloglanis  ZBK  is distinguished from all other genera of Glyptosternina  by having no post-labial groove; the lower lip is continuous with the isthmus without demarcation (vs. having either a continuous or medially interrupted post-labial groove). It is further distinguished from Oreoglanis  ZBK  and Pseudexostoma  ZBK  by having homodont (vs. heterodont) dentition in the lower jaw, and from Pseudexostoma  ZBK  by having homodont (vs. heterodont) dentition in the upper jaw, and from Glyptosternon  ZBK  by not having the gill openings extending onto the venter.

Description: 7 dorsal rays; 13-16 branched pectoral-fin rays; 6 pelvic-fin rays; 5-7 anal-fin rays. Head depressed; body elongate, depressed anteriorly. Skin smooth dorsally, but often tuberculate ventrally. Eyes minute, dorsal, subcutaneous. Lips thick, fleshy, papillated. Teeth pointed; tooth patches in upper jaw joined into a crescent-shaped band. Maxillary barbel with well-developed membrane, soft base. Gill openings narrow, not extending below pectoral-fin base. Branchiostegal membranes confluent with isthmus. Coracoid process not externally visible. No thoracic adhesive apparatus. Paired fins plaited to form an adhesive apparatus.

Distribution: Ganges and Brahmaputra drainages, India, Bangladesh, Nepal and China (Hora & Silas, 1952b; Talwar & Jingran, 1991; Chu et al., 1999).
