Diagnosis

This species is one of the largest of the genus, recognised by the length of the maxillary palps which extend to the foramen magnum; furthermore, these ants have mesosoma extremely long and narrow, with the meso and metapleural longer than wide (Fig. 3 ).

Distribution

This species shows a Neotropical distribution with records only for South America, in the Amazon rainforest ( Ortíz and Fernández 2011). It is reported here for the first time in the Department of Caquetá. In Colombia, it also has a record outside the Amazon Region, in the Department of Antioquia ( Ortíz and Fernández 2011). In the Neotropical Region, the species has also been recorded in Bolivia, Brazil, Ecuador, Peru, Guyana, Suriname and French Guiana ( Kempf 1969, Fernandez and Sendoya 2004).

Biology

Specimens record here were found in the leaf litter in the Rio Hacha Basin, being the predominant ant species in this highly conserved area (Andean-Amazonian transition zone in the Department of Caquetá).
