Differential diagnosis

Males of A. natachae sp. nov. have the RTA posterior branch single and cone-shaped, the anterior RTA branch rectangular with a curved apical margin ( Figs 4C–D View Fig , 5C–D View Fig ). Both RTA branches are similar to those of A. hespar Platnick, 1974 ( Platnick & Lau 1975: figs 39–40), A.wanlessi Platnick & Lau, 1975 ( Platnick & Lau 1975: figs 103–104) and A. inferens Chamberlin, 1925 ( Brescovit 1997: figs 7–8, 11– 13), but differ from these species by the ventral tegular projection tip being flat and squared, the slightly curved median apophysis, and the retrolateral tegular projection margin not overlapping the median apophysis ( Figs 4A–D View Fig , 5A, D View Fig ). Females of this species are differentiated from those of A. inferens ( Platnick & Lau 1975: figs 115–116; Brescovit 1992: figs 1–2, 1997: figs 9–10) by the acute posterior edge of the epigynal midpiece and the atrium lateral borders being longer and less curved ( Figs 4E–F View Fig , 5E–F View Fig ).

Etymology

The species epithet is dedicated to Natacha Merritt, friend of the authors and a taxonomy supporter.
