(Type species: Exostoma andersonii Day, 1870 , by monotypy). Gender masculine. Diagnosis: Interrupted post-labial groove; gill openings not extending onto venter; homodont dentition; strong, distally flattened teeth in both jaws; slightly crescent-shaped tooth patch in upper jaw; 10-11 branched pectoral rays. Glaridoglanis is distinguished from Oreoglanis , Pseudexostoma , Exostoma , Myersglanis , and Parachiloglanis by having an interrupted past-labial groove (Table 5). Glaridoglanis is distinguished from Glyptosternon , Euchiloglanis , and Pareuchiloglanis by having strong, distally flattened teeth in both jaws (vs. small pointed teeth). Glaridoglanis is further distinguished from Pareuchiloglanis and Euchiloglanis by having 10-11 branched pectoral rays (vs. 13-16 in Pareuchiloglanis and 12-14 in Euchiloglanis ). It is further distinguished from Glyptosternon by having the gill openings not extending onto the venter. Description: 6 dorsal rays; 10-11 branched pectoral-fin rays; 6 pelvic-fin rays; 7-8 anal-fin rays. Head depressed; body elongate, flattened ventrally to s. Eyes minute, dorsal. Lips thick, fleshy, papillated. Post-labial groove broadly interrupted medially. Teeth flattened, strong, blunt; tooth patches in upper jaw joined, formeding a slightly crescentshaped band. 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: Irrawaddy drainage, Myanmar and China (Day, 1870b; Hora & Silas, 1952b; Chu et al., 1999).
