Differential diagnosis
Females of A. miniducta sp. nov. are differentiated from most of those of the pectorosa and pacifica groups by the following features: atrium T-shaped, lateral borders short and parallel, copulatory ducts short, slightly curved (Figs 32E–F, 33G–H). Similar atria are present in females of A. simplex (Pickard-Cambridge O. 1894: pl. 18 fig. 3a) and A. porta sp. nov. (Fig. 39E), but they differ by the atrium proportions and the length of the lateral sides, respectively. Males can be differentiated by the presence of the following features: median apophysis hook-shaped, transparent lamellae absent, middle section of ventral tegular projection broad, retrolateral border with a narrow cuticular transparent edge, distal section pointed, RTA anterior branch ear-shaped, larger than the lamella-shaped posterior branch in retrolateral view (Figs 32A–D, 33A–D).
Etymology
The species epithet refers to the short copulatory ducts of this species in relation to other members of the pectorosa group.
