Habitat and distribution: Freshwater,northern New Guinea (Fig.38).

Remarks

As indicated by the total-evidence analysis, Brustiarius follows the definition and species composition proposed in previous morphological studies (Kailola 2004, Marceniuk and Menezes 2007, Marceniuk et al. 2012), with the inclusion of Brustiarius utarus sensu Betancur-R. (2009). The species in Brustiarius were treated as a species flock, based on the shallow genetic divergences found by Betancur-R. (2009).
