Diagnosis

This species is easily distinguished by sharp spiniform teeth on the median clypeal lobe and regular longitudinal striate sculpture on the head, pronotum, mesonotum, sides of mesosoma and petiole (Fig. 5 View Figure 5 ).

Distribution

This record in the Andean-Amazonian transition zone of the Department of Caquetá represents the second record of the species in Colombia, suggesting a possible distributional restriction for the Amazon rainforest ( Guerrero et al. 2018). In the Neotropical Region, the species has also been recorded in Ecuador, Peru and Brazil ( Longino 2012).

Biology

Slow-moving ants difficult to distinguish from the substrate. All specimens were extracted from sifted leaf litter from the humid forest above 1200 m in the Andean-Amazonian transition zone studied.

Notes

The Colombian specimen presents yellowish, long and flexuous hairs on the body, but shorter than in the populations from Manaus (Amazonas, Brazil). A population from Peru presents variation in the teeth of the medial clypeal lobe, as well as finer sculpting in the frontal area of the head ( Longino 2012).
