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

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).
