Diagnosis.

39.6-46.5 mm total length. Body robust. Anterior border of the frons with two prominent secondary mediofrontal tubercles. Mediofrontal tubercles large, located on base of each laterofrontal tubercle. Central tubercle with apex free. Lateroposterior tubercles distinct. Eyes large. Antennal club tri-lamellate, with lamellae long. Lacinia with apex bidentate. Mediobasal area of mentum protruding and glabrous, sometimes with scarce setae on the posterior border. Marginal pronotal groove occupying 2/3 of the pronotum anterior border. Prosternellum rhomboidal, truncate. Mesosternum pubescent, with inconspicuous and elongated scars. Metasternum pubescent anterolaterally and in lateral groove; disc smooth, delimited posteriorly to middle by punctations. Humeri pubescent, epipleura pubescent in basal 2/3. Last abdominal sternite with complete marginal groove. Anterior ventral border of the profemur with well-developed groove. Meso- and metatibia with one or two small spines.

Comments.

A South American species, with distribution in the Antilles ( Reyes-Castillo 1973). It is a species of highly variable size, Reyes-Castillo and Amat-García (2003) notes that the specimens from the Sierra Nevada de Santa Marta are larger than those from the rest of the country, with the apex of the horn free and very long.
