Distribution: All of the species are found in South America with one of them, G. waldenfelsi, reaching eastern Panama (Ratcliffe and Dechambre 1983).
Composition:The small genus Gibboryctes contains three relatively rare species.
Diagnosis: The genus is unique in having the following combination of characters: anterior tibia with four lateral teeth, head relatively short and widely triangular with an acuminate clypeus in the males and broadly rounded clypeus in the females, mandibles projecting conspicuously from beneath the clypeus, and pronotum with a deep, wide, almost triangular fovea.
Biological notes: Nothing is known of the life history of these rare insects. Adults are presumably nocturnal and attracted to lights.
