Diagnosis.

21.8-26.0 mm total length. Body subcylindrical. Anterior border of the frons with strong middle indentation, without secondary mediofrontal tubercles. Mediofrontal and laterofrontal fused, large. Central tubercle with apex not free. Lateroposterior tubercles small, slightly distinct. Eyes large. Antennal club tri-lamellate, with lamellae long. Lacinia with apex bidentate. Mediobasal area of mentum protruding and glabrous. Marginal groove widened, occupying 2/3 of the anterior margin of the pronotum. Prosternellum rhomboidal, acute. Mesosternum glabrous; mesosternal scars inconspicuous and elongated. Metasternum glabrous anterolaterally and in lateral groove; disc smooth and delimited by punctations posteriorly to laterally. Humeri glabrous and epipleura with some scarce setae basally or glabrous. Anterior ventral border of the profemur with groove. Meso- and metatibiae with small spines or unarmed.

Comments.

Distributed from Mexico to central and northern Colombia. Amat-García et al. (2004) cited this species from the Amazon region, but without citing specimens. We doubt its presence in southern Colombia. P. punctatostriatus has been collected in shady coffee plantations in Serranía del Perijá and in Sierra Nevada de Santa Marta ( Jiménez-Ferbans and Amat-García 2009).
