Diagnosis. Length 13.0-16.3 mm. Color dark brown to black. This species is distinguished from other Bolborhinum by the number and placement of the male cephalic horns. Head with four distinct horns; clypeal horn curved, directed anteriorly, located at midline of clypeal apex; two smaller horns located immediately behind the previous horn on either side of clypeal border; the fourth horn is located near the fronto-clypeal line; vertex depressed medially, with surface smooth, impuctate. Pronotum with deep, wide apical excavation; postero-superior ridge transverse, slightly sinuate medially; pronotal disc impunctate, with short, shallow longitudinal furrow; lateral surface with moderately dense to dense punctures concentrated around the lateral fovea, the apical and basal angles, and along the lateral margin.
Females similar to males, except in the shape of the head and cephalic ornamentation; dorsal surface of head with a frontal tubercle variably developed; supraocular margin laterally with straight ridge. Pronotum slightly depressed immediately behind of the apical margin, dorsally with medial furrow; pronotal disc sparsely punctate with small, moderately dense punctures concentrated near midline. |
