Fig. 16 C–F

Diagnosis

Zaitunia brignoliana sp. nov. is easily distinguished from other species of the group, except Z. afghana , by having boomerang-shaped receptacles subdivided into two lobes and lacking a stem (undivided in most other members; whereas Z. afghana have a distinct stem and the receptacles are dumbbell-shaped – cf. Figs 16 D–F and 14G–K, respectively).

Etymology

The specific epithet is given after the prominent Italian arachnologist Paolo Marcello Brignoli (1942– 1986) who described three species of Zaitunia from Iran.
