They resemble males of A. centralis, but differ by the higher number of teeth and a more curved and tapered embolus in dorsal view (Fig. 8 C). Females resemble those of A. centralis and A. parana, but differ from those of A. centralis by the spermathecae with an elongated spermathecal duct leading to a sub-spherical receptacle, with a digitiform internal projection longer or almost the same length of the receptacle (Fig. 9 F) and from A. parana by the narrow fundus of the spermathecae.</p><p>Description of holotype male</p><p>(M 1496).
