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).
