Figs 10 View Fig , 15

Diagnosis

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

Etymology

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