Dorsale stekels (totaal) : 7; Dorsale zachte stralen (totaal) : 10 - 11; Anale stekels: 1; Anale zachte stralen: 10 - 11. Easily identified by the dark black bar extending downward through the eye and the yellow-brown body color; during courtship, both males and females with 9-11 black bars on their flanks and a red border on the edge of the dorsal fins; black eye bar becomes prominent; males develop a dusky flush to their throats and lower jaw (Ref. 44091).
Largest Insularigobius recorded; possesses a relatively high scale count in horizontal series, 47-52, usually 48-50; high predorsal scale count, always fully scaled, 16-23, usually 19-20; belly anteriorly almost always scaled close to pelvic base; breast always with many embedded scales; up to five rows of teeth in upper jaw and up to six in lower jaw (Ref. 34009).
Body shape (shape guide): fusiform / normal; Cross section: circular.
A poor climber and thus restricted to the lower reaches and adjoining brackish waters; found in both altered and unaltered streams; omnivorous and a benthic feeder on filamentous algae, worms, crustaceans and insect larvae; not highly sought as food by the early Hawaiians (Ref. 44091). Benthic (Ref. 58302).
