Genus Stenogobius Bleeker, 1874
Small finger-like flaps on shoulder girdle ; tongue tip free;
head compressed, with Type B pore pattern and transverse
papillae pattern. Va disc. Gill opening equals P base. Scales
ctenoid. D VI+I,1O-11; A 1,10-11; P 15-16; LS 45-55. Vertebrae 26. Most easily confused with Awaous, which has a
broad head. A few tropical freshwater species , one in our
area . Genus is in need of revision and the species name used
here is provisional.

Genus Taenioides Lacepede, 1798
