Diagnosis
This species is recognised by having, in frontal view, inner basal margin of mandible markedly separated from anterior margin of clypeus (closed mandibles); hypostomal tooth visible in whole or in part; in lateral view, petiole with sharp apical tooth (Fig. 18).
Distribution
This species is widely distributed in the Tropics of South America (Lattke 2011). In Colombia, it is known from the Departments of Cundinamarca and Meta (Fernández et al. 2019). It is reported here for the first time in the Department of Caquetá. In the Neotropical Region, the species has also been recorded in Bolivia, Brazil, Ecuador, Peru, Guyana, Suriname, French Guiana and Venezuela (Lattke 2011).
Biology
Specimens were collected from a log on the ground, using the TSBF sampling method in an Andean-Amazonian transition zone.
