Glyptosternon McClelland, 1842   ZBK

Fig. 21

Glyptosternon McClelland, 1842   ZBK : 584. (Type species: Glyptosternon reticulatum McClelland, 1842   ZBK , by subsequent designation by Bleeker (1862-63: 12).) Gender neuter.

Glyptosternum Agassiz, 1846 : 164. (Type species Glyptosternon reticulatum McClelland, 1842   ZBK . Unjustified emendation of Glyptosternon McClelland, 1842   ZBK ). Gender neuter.

Parexostoma Regan, 1905   ZBK : 182. (Type species: Exostoma stoliczkae Day, 1877   ZBK , by subsequent designation, apparently by Jordan (1920). Gender neuter. Synonomized with Glyptosternum (= Glyptosternon   ZBK ) by Hora (1923b).

Diagnosis: Interrupted post-labial groove; gill openings extending onto venter; homodont dentition; pointed teeth in both jaws; crescent-shaped tooth patch in upper jaw; 10-12 branched pectoral rays.

Glyptosternon   ZBK is distinguished from all other genera of Glyptosternina by having gill openings extending onto the venter. Glyptosternon   ZBK is further distinguished from Oreoglanis   ZBK , Pseudexostoma   ZBK , Exostoma   ZBK , Myersglanis   ZBK , and Parachiloglanis   ZBK by having an interrupted post-labial groove (Table 5). It is further distinguished from Glaridoglanis   ZBK by having small pointed teeth in the upper and lower jaws (vs. strong, distally flattened teeth), and from Pareuchiloglanis   ZBK by having tooth patches joined into a crescent-shaped band in the upper jaw (vs. tooth patches in the upper jaw joined into a band not produced posteriorly at the sides) and 10-12 (vs. 13-16) branched pectoral-fin rays.

Description: 6-7 dorsal rays; 10-12 branched pectoral-fin rays; 6 pelvic-fin rays; 6-8 anal-fin rays. Head depressed; snout broadly rounded; body elongate, flattened ventrally to pelvic fins. Eyes minute, dorsal, subcutaneous. Lips thick, fleshy, papillated. Post-labial groove broadly interrupted medially. Teeth in both jaws pointed, tooth patches in upper jaw joined, forming a band produced posteriorly at sides (crescent-shaped). Maxillary barbel with well-developed membrane, soft base, and striated pad of adhesive skin. Branchiostegal membranes confluent with isthmus. Coracoid process not externally visible. No thoracic adhesive apparatus. Paired fins plaited to form an adhesive apparatus.

Distribution: Indus drainage; Afghanistan, Pakistan, India, Uzbekistan, Tajikistan and China, east to Irrawaddy drainage, Myanmar (Coad, 1981b; Talwar & Jhingran, 1991; Rafique, 2000)
