Distribution Notes:

Mexico to Nicaragua.

Biology:

This species inhabits mature lowland wet forest. It is most often collected in Winkler samples of sifted leaf litter and rotten wood from the forest floor.

Identification:

Very similar to P. beloceps.

Comments:

Note by Longino, 6 Nov 2013: I re-evaluated my concept of P. beloceps. DNA barcoding puts Costa Rican (La Selva) and Nicaraguan specimens in different clusters. The Nicaraguan specimens have the major worker with larger, more rectangular head, with vertex lobes smooth and shiny. This form occurs elsewhere in Nicaragua, Honduras, and Chiapas, Mexico, but so far there are no Guatemala records. The minors are indistinguishable from Costa Rican beloceps. I put this northern form in the morphospecies JTL225. Among the mounted material, the only site where both species occurred was Cerro Musún in southern Nicaragua. Pheidole beloceps was in the miniWinkler transects at 700-800m elevation; Pheidole JTL225 was in higher elevation maxiWinklers, 1000-1400m. In the database, I reidentified all material north of Musún as JTL225, including material in etoh that I did not re-examine. For Musún, I identified all material below 800m as P. beloceps; all material above as JTL225. Ethanol material should be re-examined, although minors cannot be separated at this point.
