This species was collected by leaf litter sifting. It forages diurnally as individuals in the leaf litter.
Identification
- Head and mesosoma heavily sculptured; erect hairs moderately abundant on head and mesosoma; 1st gastral tergite slightly less than half the length of gaster; body larger (HW > 0.88) . . . . . Aretidris buenaventei
- Head and mesosoma mostly smooth; erect hairs sparsely distributed on head and mesosoma; 1st gastral tergite extremely large, accounting for most of the length of gaster; body smaller (HW < 0.84) . . . . . Aretidris clousei

Biology
This is likely the same species that was included in the phylogenetic analysis of Lordomyrma (Lucky & Sarnat 2010) as 'Genus undet. PH03'. Although the outgroup sampling was very limited, the analysis suggested the genus is a close relative of Lordomyrma.
Castes
Known only from the worker caste.

Etymology
This species is dedicated to my good friend Ronald M. Clouse who collected all the type specimens.
