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.
