Diagnosis

This uncommon species is recognised by the following characteristics: inner surface of antennal scrobes and first gastral tergum smooth and shiny; body covered by long, flexible hairs; mesosoma covered fine, short striation; in lateral view, promesonotum strongly convex, superior to level of propodeum; propodeal spines less than twice as long as distance between their bases. The specimens collected in the eastern Amazon Basin are smaller than the Brazilian populations (Fig. 10 View Figure 10 ) ( Feitosa and Brandão 2008).

Distribution

This is a Neotropical species reported from Brazil, Ecuador, Peru and Venezuela and is little known in Colombia with records from Amazonas, Meta and Nariño ( Feitosa and Brandão 2008). It is reported here for the first time in the Department of Caquetá.

Biology

Species common in the leaf litter of humid forests, distributed from 200 to 1400 m elev.
