Pheidole gouldi

In Costa Rica, according to Longino (1997), gouldi is an inhabitant of seasonally dry habitats. He has encountered it in the xeric scrub of Santa Rosa National Park and along roadsides. In Campeche, Mexico, I found a colony in a double-cratered nest in dense bushes of a moist thorn woodland. (Wilson 2003)
