Pareuchiloglanis Pellegrin, 1936
: 245. (Type species:
Pareuchiloglanis poilanei Pellegrin, 1936
, by monotypy). Gender masculine.
Diagnosis
(based, in part, on Chu 1981 and Ng 2004a): Interrupted post-labial groove; gill openings not extending onto venter; homodont dentition; pointed teeth in both jaws; tooth patches in upper jaw joined into a band and not produced posteriorly at sides; 13-16 branched pectoral rays.
Pareuchiloglanis
is distinguished from
Oreoglanis
,
Pseudexostoma
,
Exostoma
,
Myersglanis
, and
Parachiloglanis
by having an interrupted post-labial groove (Table 5). It is distinguished from
Glyptosternon
,
Parachiloglanis
and
Euchiloglanis
by having tooth patches in the upper jaw joined into a band and not produced posteriorly at the sides (vs. joined into a crescent-shaped band).
Pareuchiloglanis
is distinguished from
Glyptosternon
and
Glaridoglanis
by having 13-16 (vs. 10-12) branched pectoral rays, from
Glaridoglanis
by having small pointed teeth (vs. strong, distally flattened teeth), and from
Glyptosternon
by having the gill openings not extending onto the venter.

Skin smooth dorsally, but often tuberculate ventrally. Eyes minute, dorsal, subcutaneous. Lips thick, fleshy, papillated. Post-labial groove broadly interrupted. Pointed teeth in both jaws; tooth patches in upper jaw joined into a band and not produced posteriorly at sides. Maxillary barbel with well-developed membrane, soft base, 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: Brahmaputra drainage, India, east and south to the Yangtze drainage, China and Annam drainages, southern Vietnam (Kottelat, 1989; Chu et al., 1999; Fu et. al., 2003; Ng 2004a).
