Remarks.

Compsobuthus is one of the most widely distributed genera of the family Buthidae with records from the Republic of Sudan, Ethiopia and Somaliland as the south-eastern limits of distribution for this genus ( Kovařík et al. 2016a). Despite its small body size, Compsobuthus werneri is a fairly toxic species, usually found under stones or embedded in sand or underground. It was previously documented from several localities in the Republic of Sudan (see Dunlop et al. 2018) and its range is here expanded to include four new localities representing three new states (North Kordofan, White Nile and Kassala).
