Wing status. The hind wings are about 0.5–0.7 as long as elytra and thus dysfunctional. The metepisterna are shortened, about as wide as long, markedly narrowed posteriorly. Consequently, H. rougemonti has to be considered an obligatory brachypterous species. This is in contrast with the original description. Clarke (1973: 7) noted that H. rougemonti is a winged species, but he did not indicate that he has investigated the hind wing development and metathoracal morphology.

Distribution. Until today only known from the Arsi Volcanos and the northern face of the Bale Mountains at altitudes between 2430 and 3600 m. Type locality is the northern slope of the Bale Mountains 8 km west of Dinsho (about 07°06 ʹ N 39°44 ʹ E). Clarke (1973: 3, 9) mentioned several additional collecting sites of the species on Mt. Chillalo and between Dinsho and the locality 10 km East of Adaba along the northern face of the Bale Mountains.
