| Pheidole sicaria|
Known from mid-elevation rainforest and cloud forest. The types were collected by P. S. Ward on a palm trunk. Longino (1997) found two nests respectively in a clump of aroid roots and in loose dead leaves and fragments of carton lodged on the branch of a small Ocotea tree, whose hollow stems harbored a colony of Myrmelachista.
