The remark put forward by Rose (1931, 1931 a) about difficulties for this species to survive in the Eastern Mediterranean basin seems to be confirmed in 2004.
For us, this species is noted for the first time in the N Red Sea (Sharm El-Sheikh) by El-Sherif & Aboul Ezz (2000, p.72);
For Boxshall & Halsey (2004, p.491) the subgenus (Dahl, 1912) is considered as full generic status pending phylogenetic revision of the whole family at the generic level.
