Diagnosis.

20.6-24.4 mm total length. Anterior border of the labrum slightly concave. Frontoclypeus straight or slightly concave. Frontal-clypeal suture present and strong. Internal tubercles conspicuous, joined to central tubercle by Y-shaped ridges. Central tubercle small, with apex not free and even with lateroposterior tubercles which are conspicuous and transverse. Frontal fossae glabrous or rarely pubescent. Postfrontal groove complete. Mediobasal area of the mentum glabrous. Marginal groove over anterior border of the pronotum slightly expanded. Mesosternum glabrous. Metasternum with scarce pubescence anterolaterally and in lateral groove; disc not delimited by punctations. Meso- and metatibiae with small spines. Humeri with scarce setae; epipleura glabrous; anterior vertical face of elytra pubescent.

Comments.

P. marginatus has been recorded from Argentina, Bolivia, Brazil, Colombia, French Guiana, Peru and Suriname ( Gillogly 2005; Jiménez-Ferbans et al. 2013). Some specimens from SNSM have some differences with the characteristics described by Gillogly (2005) and could be a new species.
