Figs 10, 15

Diagnosis

Males of Hatitia cajuata sp. nov. resemble those of H. sericea by the conical prolateral tibial apophysis (Figs 6H, 10H) but differ by the short, curved retrolateral tibial apophysis and the laminar median apophysis furrowed in the middle (Fig. 10C–H). Females of Hatitia cajuata resemble those of H. yhuaia, H. riveti, H. winayhuayna sp. nov., and H. zarate sp. nov. by the epigynal plate with parallel lateral lobes (Figs 1H, 3H, 4F, 5L, 6I, 7F, 8F, 10I, 11I). They differ from them by the absence of a hood in the anterior region of the epigynal plate (Fig. 10I).

Etymology

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