3A60CC0BFFDAFFF5C39FFAE9FBFC73EC.taxon	discussion	Comments. Orosius aegypticus was described by Ghauri (1966) from a single male from Egypt. While considering it a distinct species based on the aedeagus structure Ghauri considered that it might be an aberrant form of Orosius albicinctus. However, the same form of aedeagus was recorded from Pakistan (Khatri & Webb, 2010, Khatri, et al., 2011) based on a single male and was concluded to be a valid species. Female specimens were also assigned to be this species. Fletcher et al. (2016) used some of these females in their molecular analysis of Orosius in Australia. These specimens aligned to albicinctus and on this result they based their proposed synonymy of aegypticus with albicinctus. It cannot be certain that these females were conspecific with the male recorded as aegypticus. They could just have easily been albicinctus. Since we have now found male Orosius specimens in KSA that are identical with the aegypticus type we consider that the species should continue to be regarded as distinct. Clearly further molecular analysis based on males may resolve the position.	en	El-Sonbati, Saad A., Wilson, Michael R., Al Dhafer, Hathal M.
