Diagnosis

The genus and species can be distinguished from any other Myrmicine ant by a posteromedian portion of abdominal tergum VI and anteromedian portion of abdominal tergum VII with several minute, cylindrical micro-pegs, each bearing a hair on apex (Fig. 9 ) ( Fernández et al. 2014).

Distribution

Kempfidris inusualis is a Neotropical species restricted to the Amazon rainforest. In Colombia, it is only known from the Department of Amazonas ( Castro et al. 2018). It is reported here for the first time in the Department of Caquetá. In the Neotropical Region, the species has also been recorded in Ecuador, Peru, Brazil and Venezuela ( Fernández et al. 2014, Camacho and Feitosa 2016).

Biology

This species was collected in the leaf litter in secondary forest near a fallen log in an Andean-Amazonian transition zone in the foothills of Amazonia.

Notes

Fernández (2007) mentions that the morphological variability of the species is low, finding a variation in colouration, with more than one difference in the dorsal face of the propodeum and in the propodeal ridges, attributing this variation to the geographical distribution of the species.
