Probolomyrmex dentinodis

All known specimens of this species were obtained from leaf-litter samples collected in mature lowland Amazon forests (40m and 200m).

Identification
Petiole higher than long, with the petiolar teeth well developed and forming a conspicuous posterior bifurcation in dorsal view. Subpetiolar process well developed and subrectangular. Prora present. First gastral tergite with a dorsal protuberance on the posterior region.

The subrectangular shape of the subpetiolar process makes this species similar to Probolomyrmex petiolatus. However, P. dentinodis can be easily distinguished from the latter by the presence of a pair of propodeal and petiolar teeth and by the presence of the prora.
