Comments: The type locality of this species is composed of a small terra-firme stream (not affected by large rivers flooding during the wet season) and adjacent pools that drain into the Igarapé do Ubím, a tributary of the Lago Amanã.  Collected under dense forest vegetation commonly found  in central Amazon upland areas with <i>Mauritia flexuosa palm trees.  The collection site is characterized by black water with high transparency, width of up to about 2 m and depth at the stream bed up to about 0.5 m.  Mostly encountered in adjacent pools and next to palm-tree roots, where depth was about 0.1 m or less (Ref. 95522).
