Pheidole carinote

This species occurs in lowland rainforest leaf litter. It is known from numerous Winkler samples of sifted leaf litter from the Osa Peninsula in Costa Rica. Major workers and minor workers occur in Winkler samples. A minor worker was collected in the stomach contents of a dendrobatid frog ("Dendrobates granuliferus" on label).

Costa Rica (Osa Peninsula).

With the morphometric profile and habitus of P. harrisonfordi (with which it is sympatric) and many other small Pheidole. The frontal carinae of the minor worker are greatly enlarged, laminar, and projecting over the clypeus, a condition unique to this species. The major workers are very similar to major workers of P. harrisonfordi, but with frontal carinae larger, more elevated and slightly projecting (the frontal carina character is less well developed in major workers than minor workers, and makes majors of P. carinote more difficult to identify than minor workers).
