Remarks. Cameron (1986: 266) provided the following description of this species: “Identical in coloration with P. punicipes (black, with the legs red and the tegulae white), but smaller and narrower; the antennae shorter, being scarcely longer than the abdomen, while in P. punicipes they are nearly as long as the thorax and abdomen together; the ovipositor much longer, being fully three fourths of the length of the abdomen; the metanotum shining and impunctate; the petiole shining and scarcely punctured, and with an oblique punctured depression on each side at the apex above; the abdomen longer, the segments not so strongly punctured, and with a wider impunctate band at the apices; the wings have a darker tint, and have the stigma livid testaceous. The pleurae and head are punctured, but not strongly; palpi yellow; sheath of the ovipositor densely pilose.”

Distribution. Mexico (D.F.).
