Myersglanis Hora & Silas, 1952b   ZBK : 19. (Type species: Exostoma blythii Day, 1869   ZBK , by original designation). Gender masculine.

Diagnosis (based, in part, on Vishwanath & Kosygin 1999): Continuous post-labial groove; gill openings not extending onto venter; homodont dentition; pointed teeth in both jaws; tooth patches in upper jaw joined and not produced posteriorly at the sides; 10 or 16-19 branched pectoral rays.

Myersglanis   ZBK is distinguished from Glyptosternon   ZBK , Glaridoglanis   ZBK , Euchiloglanis   ZBK , Pareuchiloglanis   ZBK and Parachiloglanis   ZBK by having a continuous post-labial groove (Table 5). Myersglanis   ZBK is distinguished from Exostoma   ZBK and Pseudexostoma   ZBK by having tooth patches joined (vs. separated) in the upper jaw. It is further distinguished from Exostoma   ZBK by having pointed teeth in both jaws (vs. teeth oar-shaped, flatted distally). Myersglanis   ZBK is distinguished from Oreoglanis   ZBK and Pseudexostoma   ZBK by having homodont dentition in the upper and lower jaws (vs. heterodont dentition in the lower jaw in Oreoglanis   ZBK and heterodont dentition in the upper and lower jaws in Pseudexostoma   ZBK ).

Description: 7 dorsal rays; 10 or 16-19 branched pectoral-fin rays; 6 pelvic-fin rays; 8 anal-fin rays. Head depressed; body elongate, depressed anteriorly. Eyes minute, dorsal, subcutaneous. Lips thick, fleshy, papillated. Teeth pointed; tooth patches in upper jaw joined, ovoid-shaped; that in lower jaw divided medially, pointed posteriorly at sides. Maxillary barbel with well-developed membrane, soft base, and 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: Ganges and Irrawaddy drainages, India and Nepal (Vishwanath & Kosygin, 1999).
