Keys including this Species


Known from the type locality; and from near Villavicencio, Meta; and from Mocoa, Putumayo, 610 m, col. Charles Kugler. The record of P. oliveirai recorded by Fernandes et al. (1994) from San Antonio de Posse, São Paulo, is in error, due to my own misidentification. The species they studied is actually Pheidole oxyops, a member of the diligens group (q.v.). (Wilson 2003)
