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 View Fig , 33G–H View Fig ). Similar atria are present in females of A. simplex (Pickard-Cambridge O. 1894: pl. 18 fig. 3a) and A. porta sp. nov. ( Fig. 39E View Fig ), 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 View Fig , 33A–D View Fig ).

Etymology

The species epithet refers to the short copulatory ducts of this species in relation to other members of the pectorosa group.
