Differential diagnosis
Males of A. stigma sp. nov. are differentiated from all those of the pectorosa and pacifica groups by the presence of the following features: middle section of ventral tegular projection broad, retrolateral edge with a translucent edge, prolateral surface also distended; distal edge of median apophysis flat and curved, ventral edge with a transparent lamella (Figs 50E–F, 51A–D). RTA anterior branch spine-shaped with a blunt tip, longer than posterior branch, which is shaped as a curved lamella. Coxae II and III with a mid-ventral tubercle, coxa IV with two tubercles (Figs 50E–F, 51A–F). Ventral tegular projection with broad middle sections and translucent retrolateral edges are also present in A. zorynae (Durán-Barrón et al. 2016: figs 5, 9), A. pacifica (Dondale & Redner 1982: fig. 336), A. tonoi sp. nov. (Fig. 46A) and A. miniducta sp. nov. (Fig. 32A). Similar RTA are present in A. scopulata (Pickard-Cambridge F. 1900: pl. 7 fig. 17), A. simplex (Pickard-Cambridge O. 1896: pl. 7 fig. 11) and A. tonoi sp. nov. (Fig. 47A, D).
Etymology
The species epithet is derived from the Latin ‘ stigma ’ (‘mark’ or ‘brand’), in reference to the several dark spots on the scutum and epiandrous region.
