Material examined: Egypt: 1 ò (17.4 mm) ( TAU SLR 1475), Nabq, Sinai, coll. 19 May 1968; 1 ñ (18.1 mm) (NCHUZOOL 13623), Nabq-El Arwashie, Sinai, coll. S. Barbaresi et al., 14 Oct. 2004. Saudi Arabia: 4 òò (16.5–19.9 mm) (NCHUZOOL 15093), Al Darb (17°26'53.4"N, 17°26'53.4"N), coll. A. J. Kumar, 25 Apr. 2017.

Distribution: South Africa to Somalia, Madagascar, Egypt (Red Sea), Saudi Arabia (Red Sea), Eritrea, Yemen, Oman, UAE and Iran.

Remarks: The southernmost record of this species from Natal, South Africa ( Crane 1975) needs to be substantiated; confirmed records extend southward to Kosi Bay (near the Mozambican border) ( Peer et al. 2015). The northernmost record is from Qeshm Island, Iran along the northern coast of the Arabian/Persian Gulf ( Naderloo 2017). COI data confirm connectivity of populations between the Red Sea and the East African coast ( Fig. 4 ).
