Biology

Specimens were collected above and below a waterfall along the Rio Mucajaí. The river in that region was characterized by steep banks and with dense forest along the shore; large amounts of aquatic plans of the family Podostemonacease were present in the area, the water acidic (pH 5.8) and well oxygenated (91% saturation) (Ref. 84053).
