Remarks.

Species recorded in the cloud forests of the western slopes of the Andes; however, there is only a single record from this locality cited by Génier (2009) and may be erroneous. In the Amazon it was registered in the lowland evergreen and evergreen foothill forests from 150-1100 m a.s.l. Collected with flight interception traps and pitfall traps, baited with carrion and human feces.
