16.3–19.8 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 conspicuous and conical. Eyes reduced. Antennal club tri-lamellate, lamellae short. 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 oval and distinct. Metasternum glabrous anterolaterally and in lateral groove; disc smooth and delimited by punctations posteriorly to laterally.

Comments
Species very similar to R. maillei, from which it differs by its larger size, reduce punctation on the pronotum, which do not reach the mid zone and the metasternal disc not abundantly punctate.
