Glaridoglanisis distinguished from Oreoglanis, Pseudexostoma, Exostoma, Myersglanis, and Parachiloglanisby having an interrupted past-labial groove (Table 5). Glaridoglanisis distinguished from Glyptosternon, Euchiloglanis, and Pareuchiloglanis byhaving strong, distally flattened teeth in both jaws (vs. small pointed teeth). Glaridoglanisis further distinguished from Pareuchiloglanisand Euchiloglanisby having 10-11 branched pectoral rays (vs. 13-16 in Pareuchiloglanisand 12-14 in Euchiloglanis). It is further distinguished from Glyptosternonby 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.
