Onthophagus hecate. Representative male with a large pronotal horn with four protuberances: A) Dorsal, B) Lateral. Representative male with a small pronotal horn with two protuberances: C) Dorsal, D) Lateral. Representative female: E) Dorsal, F) Ventral. Black arrows indicate bifurcation and protuberances. White lines indicate the pronotum width representing the body size (solid line in A) and pronotal horn size (dashed lines in A and E). The black dashed line in (B) indicates the clypeus height used in this study. Females do not develop a prominent clypeus; however, we measured its height using equivalent points (F). Scale bars: 1 mm. One scale bar is used for A, C, and E, and a second scale bar for B and D, and a third for F.
