Fig. 18

Chimarrichthys Sauvage, 1874  ZBK  : 332. (Types species: Chimarrichthys davidi Sauvage, 1874  ZBK  , by monotypy). Gender masculine.

Euchiloglanis Regan, 1907  ZBK  : 158. (Types species: Chimarrichthys davidi Sauvage, 1874  ZBK  , by being a replacement name. Proposed as a replacement for Chimarrichthys Sauvage, 1874  ZBK  , then considered to be preoccupied by Cheimarrichthys Haast, 1874  ZBK  in fishes). Gender masculine.

Coraglanis Hora & Silas, 1952b  ZBK  : 12. (Type species: Euchiloglanis kishinouyei Kimura, 1934  ZBK  , by original designation). Gender masculine. Synonomized with Euchiloglanis  ZBK  by Chu (1981).

Diagnosis (based, in part, on Chu 1981): Interrupted post-labial groove; gill openings not extending onto venter; homodont dentition; pointed teeth in both jaws; tooth patches in upper jaw joined into cresent-shaped band; 12-14 branched pectoral rays.

Euchiloglanis  ZBK  is distinguished from Oreoglanis  ZBK  , Pseudexostoma  ZBK  , Exostoma  ZBK  , Myersglanis  ZBK  , and Parachiloglanis  ZBK  by having an interrupted post-labial groove (Table 5). Euchiloglanis  ZBK  is distinguished from Pareuchiloglanis  ZBK  by having a crescent-shaped tooth patch in the upper jaw. i.e., a band that curves posteriorly at the sides (vs. not curved posteriorly). It is distinguished from Glyptosternon  ZBK  by having the gill openings not extending onto the venter, and from Glaridoglanis  ZBK  by having small pointed teeth in both jaws (vs. strong, distally flattened teeth).

Description: Dorsal fin with 7 rays; pectoral fin with 12-14 branched rays; 6 pelvicfin rays; 6 anal-fin rays. Head depressed; snout broadly rounded; body elongate, flattened ventrally to pelvic fins. Eyes small, dorsal, subcutaneous. Lips thick, fleshy, papillated. Post-labial groove broadly interrupted at middle. Upper jaw teeth pointed, tooth patches in upper jaw joined into cresent-shaped band. 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: Yangtze drainage, China (Chu, 1981; He, 1995; Fu et. al., 2003).
