Pheidole lancifera

I raised the type colony from a dealate queen I captured on the floor of lowland rainforest near Manaus; the colony, after growing to contain several hundred workers, produced males. A colony found at Cuzco Amazónico by Cover and Tobin was nesting in a rotten stick in leaf litter on the floor of terra firme forest, and contained males on 12 June. (Wilson 2003)
