: 19. (Type species:
Exostoma blythii Day, 1869
, by original designation). Gender masculine.

Myersglanis
is distinguished from
Glyptosternon
,
Glaridoglanis
,
Euchiloglanis
,
Pareuchiloglanis
and
Parachiloglanis
by having a continuous post-labial groove (Table 5).
Myersglanis
is distinguished from

and
Pseudexostoma
by having tooth patches joined (vs. separated) in the upper jaw. It is further distinguished from
Exostoma
by having pointed teeth in both jaws (vs. teeth oar-shaped, flatted distally).
Myersglanis
is distinguished from
