Figs 7, 15

Diagnosis

Males of Hatitia zarate sp. nov. resemble those of the yhuaia group by the conical median tibial apophysis (Figs 3E, G, 4D–E, 5H–I, 8D–E, 9D–E, 10E–H), but differ by the filiform and elongated retrolateral tibial apophysis and the long and truncated ventral tegular projection (Fig. 7C–E). Females of Hatitia zarate resemble those of the yhuaia group by the epigynal plate with parallel lateral lobes (Figs 1H, 3H, 4F, 5L, 6I, 7F, 8F, 10I, 11I). They differ by the epigynal plate having a semicircular and narrow hood in the anterior region (Fig. 7F), whereas a large hood and atrium are present in H. yhuaia (Figs 1H, 3H), in H. riveti (Figs 4F–G, 5L; see Dupérré 2023: fig. 12c), in H. sericea (Fig. 6I), in H. winayhuayna sp. nov. (Fig. 8F); or hood absent in H. cajuata sp. nov. (Fig. 10I).

Etymology

The specific epithet is toponymic in apposition and refers to the type locality.
