Diagnosis

With the general habitus and morphometric profile of P. tschinkeli, with which it is sympatric. Minor and major worker: katepisternum and side of propodeum uniformly foveolate versus with conspicuous rugulae overlaying foveolate sculpture; propodeal spines short, tapering, with sharp tips, versus long, not tapering, tips blunt.

Biology

This species occurs in wet forest habitat. It is locally abundant and recruits heavily to baits on the forest floor. Major and minor workers frequently occur together at baits. The nest is unknown.

Etymology

The species is named for Dr. Jorge Leon Cortes, Director of the San Cristobal campus of the Colegio de la Frontera Sur, Chiapas, Mexico. Jorge was an extremely generous and effective host during LLAMA project sampling in Chiapas. He is an energetic field biologist actively promoting biological studies in Chiapas.
