Records examined.

NAPO: B. P. La Cascada, Parque Nacional Sumaco, 1300 m (1 specimen CEMT). ZAMORA CHINCHIPE: Chito Río San Francisco, 1800 m (1 specimen CEMT); El Tambo Reserva El Colibri 2080 m (17 specimens CEMT).

Temporal data.

Collected in March and May.

Remarks.

Inhabits the evergreen foothill forests and lower evergreen montane forests throughout the Amazonian range from 1300-1800 m a.s.l. In the Andean region, it was recorded in the montane cloud forests from 1800-2080 m a.s.l. This species was collected with pitfall traps baited with human feces. According to Rivera-Cervantes and Halffter (1999), the previous records from Mexico are erroneous.
