Type material. Uruguay: Colonia. Holotype ♀: Cerros de San Juan [34°13′S 57°55′W], 30 September 1984, E. Gudynas, G. Skuk & J.C. Gambarotta ( MNHN 1372 View Materials ). GoogleMaps

Etymology. The specific epithet is a patronym in honour of my friend, Rafael Cobo.

Other material examined. Known only from the type specimen.

Diagnosis. The female of A. coboi can be distinguished from those of all other species in the genus by the shape of their spermathecae ( Fig. 2D View FIGURE 2 ) with an apical lobe diagonally directed; similar to that of A. indiamuerta from which it differs by the more numerous retrolateral spines on tibia II and the labium shape ( Fig. 2B, E View FIGURE 2 ). Males are unknown.
