Habitat

Premontane rain forest and Tropical Lower Montane rain forest life zones.

Distribution

Ranges from Costa Rica (Cartago) to Panama (Chiriqúi to Coclé). In Costa Rica, this species is apparently rare, having been collected only near Tapantí and Moravia in Cartago Province and near Cariblanco in Alajuela Province. In Panama, it has been collected mostly in the Fortuna Dam region, at Cerro Colorado (both Chiriquí), at Santa Fe in Veraguas and at El Valle and El Copé in Coclé Province.
