The striped grunter (Hephaestus obtusifrons) is a species of freshwater ray-finned fish, a grunter from the family Terapontidae.

It is found only in the Bewani Mountains in the headwaters of the Pual River system in Papua New Guinea and the upper Sermowai River, Western new Guinea, Indonesia.

[3] [2] It is found in high altitude, fast flowing mountains streams.

[2] This species reaches a length of 12.5 cm (4.9 in).

[2] The fishes name in Latin = obtusus, obtuse; frons, front, presumably referring to its “even blunter snout” compared to the similar Hephaestus transmontanus which was described in the same publication.
