Etymology. The specific name is a noun in apposition from the type locality name.
Diagnosis. Males differ from those of all other species of the genus by the following combination of characters: PA conspicuous and prolaterally bended; BTA developed and placed medially on prolateral tegular surface; serrated area absent; PA continuous to PS; DTP on dorsal tegular surface, conspicuous in prolateral view; embolus inserted obliquely on ventral view, embolar base elongated and thin (Fig. 206 A–C). Females are similar to those of A. nattereri (Fig. 67 D), A. rufipes (Fig. 72 D), A. xenus (Fig. 214 A), A. azaghal (Fig. 148 D), A. echinus (Fig. 212 A) and A. tutu (Fig. 143 D) by presence of two unilobed receptacles, differing from all of these species but A. tutu, by the irregular receptacles. They differ from those of those of A. tutu by the laterally directed receptacles (Fig. 206 D).
