Diagnosis
This species is distinguished from the other Probolomyrmex species by the presence of subpetiolar process well developed, ventrally concave to sub-rectangular, with the postero-ventral angle acute and directed towards the gaster; prora and protuberance on the posterior region of the first gastral tergite present. (Fig. 22)
Distribution
This is the first record of the species for Colombia. Previously, this species had been recorded in Guyana, Peru and Venezuela. (Oliveira and Feitosa 2019).
Biology
The specimens were collected in leaf litter in the cloud forest in the Andean-Amazonian transition zone of Caquetá.
Notes
We document here the first case for the species of an ergatoid queen (Fig. 23). The ergatoid queen has developed compound eyes and ocelli; further, the mesosoma is a little wider and higher than workers. The shape of the subpetiolar process in the ergatoid queen and the worker is identical, this feature being important to separate P. kelleri from any other species of this genus.
