Relevant Information:

Brachyglanis, Leptorhamdia and Myoglanis along with Gladioglanis and the members of the Nemuroglanis subclade (Ferraris 1988) were assigned by Lundberg et al. (1991) to a large unnamed monophyletic group characterised by the loss of a free orbital rim around the eye. For further information read the referenced paper by DoNascimiento, C. and J.G. Lundberg, 2005. Habitat: M. potaroensis is a demersal (living at or near the bottom of the water body) species. The species is very habitat specific, living on banks of submerged litter, in rivers with relatively fast flow. Can occur in relatively small forest streams with sufficient flow to keep the litter banks from becoming anoxic. Etymology: The specific name potaroensis: From Potario a river in Guyana.

IUCN Red List

The species is relatively widespread, and it is likely to occur all over the Negro basin. While the recent cyanide spill is of concern, it is unclear exactly what effect this may have had on the species. Due to its wider distribution than previously thought, it is accordingly assessed as Least Concern, but does need updating, (IUCN 2009).
