Language:

Main Ref.	Hoese, D.F. and G.R. Allen, 2015
Remarks	Glossogobius microcephalus is known only from the Lake Tebera basin, including the main lake and in-flowing tributaries, located in the Southern Highlands of Papua New Guinea; the type locality consisted of a small stream flowing into Lake Tabera about 4 km east of the lake; clear water with temperature 21°C and pH values of 7.8 at the time of collection; the main lake and stream lie at an elevation of approximately 795 m; lake Tebera is situated in a narrow, elongate basin, about 10 km long and 1.5 km wide; the basin is surrounded by steep mountains that rise to about 1000 m elevation; isolated from the Erave-Purari system, may be connected via subterranean flow; the lake contains floating rafts of aquatic vegetation and the shoreline is swampy and lined with tall grass; the stream is 3-5 m in width with a maximum depth of one m; the new species is relatively common on the mainly gravel/rock bottom; Melanotaenia herbertaxelrodi was the only other fish observed (Ref. 103536).
