Fig. 25

Pareuchiloglanis Pellegrin, 1936   ZBK : 245. (Type species: Pareuchiloglanis poilanei Pellegrin, 1936   ZBK , 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   ZBK is distinguished from Oreoglanis   ZBK , Pseudexostoma   ZBK , Exostoma   ZBK , Myersglanis   ZBK , and Parachiloglanis   ZBK by having an interrupted post-labial groove (Table 5). It is distinguished from Glyptosternon   ZBK , Parachiloglanis   ZBK and Euchiloglanis   ZBK 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   ZBK is distinguished from Glyptosternon   ZBK and Glaridoglanis   ZBK by having 13-16 (vs. 10-12) branched pectoral rays, from Glaridoglanis   ZBK by having small pointed teeth (vs. strong, distally flattened teeth), and from Glyptosternon   ZBK 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).
