New record for Yemen and new record for the Palaearctic ecozone ( sensu Löbl and Löbl 2016 ). The species can be inserted in the key to the Arabian Onthophagini ( Ziani et al. 2019 ) as follows: 26. Pronotal punctation simple or ocellate on disc; quite glossy; major males with clypeus produced to a blunt point, which is strongly reflexed, and with vertex of the head produced in a pair of unconnected horns, very broad and directed backward at the base, with a small sharp tooth on the outer edge of each, beyond which they curve upward and are tapered, bisinuate, and sharp at the tip; female margin of clypeus is truncate at middle; blackish brown, elytra with basal and apical yellowish red spots which are usually confluent. Length 5.5 to 7.0 mm.................................................................................... Onthophagus ( Onthophagus ) falsus Gillet, 1925 — Pronotal punctation raspish on disc.......................................................... 26 ′ 26′ Pygidial largest punctures close on disc, separated by less than one diameter; pronotum dull; head not sinuate near obviously produced genae; clypeofrontal carina with a very long backwards horn, in major males, sometimes extending beyond pronotal hind margin; pronotum without obvious gibbosities; blackish brown. Length 4.5 to 6.0 mm.............. Onthophagus aeneopiceus d’Orbigny, 1902 — Pygidial largest punctures spaced on disc, separated by one diameter, or more; pronotum glossy; head barely sinuate near obviously produced genae; clypeofrontal carina with a short backwards horn, in major males, as long as the occipital carina, or a little more, pronotum with an anteromedian bilobate gibbosity; blackish brown, elytra sometimes with apical dark red band. Length 5.0 to 6.0 mm.............................................. Onthophagus trapezicornis d’Orbigny, 1902
