Remarks

A dark species that often has a yellow apical margin on the scutellum and a small pale area on and / or near the postalar callus. It can be identified in the male without dissection if enough of the hypopygial structures are visible ( Ebejer 1998: 225, figs 74–75). The postgonite is particularly narrow and curved at the tip; the apex of the basiphallus is blunt, like that of A. claridgei . Upon dissection, the pregenital sternite is very distinctive with its approximately square shape, sclerotized at its lateral and anterior borders and along the midline where, being very heavily sclerotized and narrow, gives this part the appearance of a long spine.

Females of these three species named above are not separable from each other unless associated with males.

Distribution

Tunisia, United Arab Emirates ( Ebejer 1998, 2008). New records for Israel and Jordan.
