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.
