Comments: Type specimens were collected in small coastal streams flowing through well-preserved Atlantic forest; in localities between 100 and 370 m a.s.l., always in rocky substrate with fast flowing, clear water, under direct sunlight, and depths between 10 and 50 cm.  Underwater observations indicate that this species is most active during the night, grazing on the bottom (Ref. 57859).
