Fig. 25

Pareuchiloglanis Pellegrin, 1936 : 245. (Type species: Pareuchiloglanis poilanei Pellegrin, 1936 , by monotypy). Gender masculine.

Diagnosis (based, in part, on Chu 1981 and Ng 2004a): Interrupted post-labial groove; gill openings not extending onto venter; homodont dentition; pointed teeth in both jaws; tooth patches in upper jaw joined into a band and not produced posteriorly at sides; 13-16 branched pectoral rays.

Pareuchiloglanis is distinguished from Oreoglanis , Pseudexostoma , Exostoma , Myersglanis , and Parachiloglanis by having an interrupted post-labial groove (Table 5). It is distinguished from Glyptosternon , Parachiloglanis and Euchiloglanis by having tooth patches in the upper jaw joined into a band and not produced posteriorly at the sides (vs. joined into a crescent-shaped band). Pareuchiloglanis is distinguished from Glyptosternon and Glaridoglanis by having 13-16 (vs. 10-12) branched pectoral rays, from Glaridoglanis by having small pointed teeth (vs. strong, distally flattened teeth), and from Glyptosternon by having the gill openings not 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. Post-labial groove broadly interrupted. Pointed teeth in both jaws; tooth patches in upper jaw joined into a band and not produced posteriorly at sides. Maxillary barbel with well-developed membrane, soft base, striated pad of adhesive skin. 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: Brahmaputra drainage, India, east and south to the Yangtze drainage, China and Annam drainages, southern Vietnam (Kottelat, 1989; Chu et al., 1999; Fu et. al., 2003; Ng 2004a).
