Remarks.

Inhabits the lowland evergreen forests, evergreen foothill forests, and evergreen lower montane forests in the Amazonian range from 200-1500 m a.s.l. Collected with flight interception traps and pitfall traps baited with carrion, human feces and dead chilopods. According to Boucomont (1932), this species was recorded in the coastal region too (Bucay, Guayas). However, we consider this record possibly erroneous.
