Identification
provided by Antweb
This species is a known only from queens and males. P. leptosus queens differ from those of P. simplex by the possession of a wider, more broadly rounded head (CI 0.77-0.82 in P. leptosus, versus 0.69-0.77 in P. simplex), shorter eyes (REL2 0.59-0.63 in P. leptosus versus 0.65-0.80 in P. simplex), more divergent frontal carinae, and narrower profemur (FI 0.42-0.47 in P. leptosus versus 0.49-0.55 in P. simplex). The differences between P. leptosus and P. pallidus queens are more subtle. All of their measurements and indices overlap, although P. leptosus tends to be smaller and (more importantly) to possess a more broadly rounded head. The most important distinction between the two species lies in the sculpture of the frons and vertex: finely punctate on a predominantly smooth, shiny background in P. leptosus; more coarsely punctate on a sublucid, coriarious background in P. pallidus. Despite some size-related sculptural variation in P. pallidus even the smallest P. pallidus queens possess more strongly developed coriarious sculpture on the head than P. leptosus queens. The postpetiole and gaster of P. leptosus also tend to be shinier than those of P. pallidus. There are slight differences in the male genitalia of the two species, as described in Ward (1985).
