New Neogene hyracoid specimens from the Peri-Tethys region and East Africa

This contribution describes and interprets fossil hyracoids from four localities in the Peri-Tethys region and one in East Africa. Two of the Peri-Tethyan localities (Ad Dabtiyah, Saudi Arabia and Reguba, Libya) are of basal Middle Miocene age (MN 5=P III, ca. 16.5 Ma), the third (Beglia, Tunisia) is basal Vallesian (ca. 11-10.5 Ma) and the fourth (Maragheh, Iran) is Late Miocene (MN 12=P VII, ca. 9.5-7 Ma). The East African locality, Bukwa, Uganda, is basal Middle Miocene in age (ca. 17.5 Ma). A new genus and species of hyracoid, Regubahyrax Selleyi, is described from Libya, characterised by lower molars ornamented by well developed cristids; and spurs and a new species, Prohyrax bukwaensis, is described from East Africa, intermediate in dimensions between Prohyrax tertiarius from the Early Miocene of Namibia, and Prohyrax hendeyi from the basal Middle Miocene of the same country. The Saudi Arabian hyracoid is attributed to Afrohyrax championi and the Tunisian and Iranian ones to Pliohyrax kruppi or rossignoli and Pliohyrax graecus, respectively.
