Abstract
We address the taxonomic position of Orthodactylus olivaceus Karsch, 1881, the type species of the genus Orthochirus Karsch, 1892. For over a century, this taxon was considered a synonym of Orthochirus scrobiculosus (Grube, 1873); however, the latter was recently limited to Central Asia (Turkmenistan) (Kovařík et al., 2020). Analysis of Karsch’s holotype confirmed that Orthochirus olivaceus (Karsch, 1881), is a valid species. Its type locality published as “Sicily” is clearly incorrect. It is a senior synonym of Butheolus aristidis Simon, 1882, syn. n., described from Sudan (Nubia). We confirm its distribution in northern Sudan and southern Egypt.
