Tribe Sphenophorini Lacordaire

Six genera but over 100 species of this tribe occur in Costa Rica and Panama. They are characterized by the form of the articulation between the femur and tibia which consists of a set of flanges and brackets, lack of a second small apical tibial tooth, sternite 9 is present in males ( Kuschel 1995) and the scutellum is triangular in shape, widest near the base.
