Diagnosis.

41.2-52.7 mm total length. Body robust. Anterior border of the frons with two prominent secondary mediofrontal tubercles. Mediofrontal tubercles small, located on base of each laterofrontal tubercle. Central tubercle with apex slightly free. Lateroposterior tubercles distinct. Eyes large. Antennal club tri-lamellate, with lamellae long. Lacinia with apex bidentate. Mediobasal area of mentum protruding and glabrous. Marginal pronotal groove occupying 2/3 of the pronotum anterior border. Prosternellum rhomboidal, acute. Mesosternum with some sparse setae, with inconspicuous and elongated scars. Metasternum pubescent anterolaterally and in lateral groove; disc smooth and delimited by punctations posteriorly to middle. Humeri pubescent, epipleura pubescent in basal 2/3. Last abdominal sternite with incomplete marginal groove. Anterior ventral border of the profemur with conspicuous groove. Mesotibia with one or two small spines, metatibia unarmed.

Comments.

Distributed from Panama to Argentina and Trinidad and Tobago ( Reyes-Castillo 1973). This species sometimes is confused with P. punctiger , but is distinguished by its larger size and incomplete marginal groove in last abdominal sternite (complete in P. punctiger ).
