Diagnosis

The male of this species is recognized by the shape of the RTA, which is straight and strongly tapered towards the sharp tip ( Figs 2 View Fig. 2 B – C, 3 A – B); the female has a wide epigyne with two triangular atria divided by a thin septum ( Figs 1 View Fig. 1 E, 3 C), very different from that of A. zavattarii Caporiacco, 1941 in   which the atria are covered and the septum invisible from the outside.

Etymology

The name refers to the large crater-like pit at the base of the cymbium.
