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, truncate. Mesosternum glabrous, except for a few short setae on the anterior margin; mesosternal scars inconspicuous and elongated.

Comments
This is the most common species above 1500 m a.s.l. in Sierra Nevada de Santa Marta. P. unimagdalenae is similar to P. punctatostriatus, from which it differs by having internal tubercles large and humeri with long setae at the very base.
