Oceania: Papua New Guinea. Glossogobius robertsi is known from several locations from the Upper Fly River system, usually in creeks above 500 m elevation. Also possibly known from the Ajkwa River in the Timika region of Papua Province (Indonesia), which lies approximately 500 km west of the Upper Fly (Ref. 80299).

Short description
Morfologi | Morfometri
Taggstrålar i analfenan 1; Mjukstrålar i analfenan: 8. A species of Glossogobius with mental frenum formed by short lateral lobes; cheek and operculum naked; predorsal scaled to near eye; pectoral base and prepelvic area only partly scaled; second dorsal fin-rays I,9-10; anal-fin rays I,8; pectoral rays usually 19; predorsal scale count 16-22; pelvic fin oval, slightly thickened, length subequal to or slightly longer than wide; midsides with large brown spots (much larger than eye length); no black spot posteriorly on first dorsal fin; cheek papilla lines composed of single row of papillae; papilla line 6 absent and vertebrae usually 12+16.
Glossogobius robertsi is easily separated from other species (Glossogobius
celebius, G. torrentis, G. coatesi and other species described as new herein) with a developed lobed mental frenum by the large spots on the side of the body, the reduced scale coverage on the pectoral base and prepelvic area, short round pelvic fin and absence of opercular scales (Ref. 80299).
