Diagnosis

Males of Hatitia riveti differ from those of other species in the yhuaia group by having palps with an enlarged, subquadrate and bilobed ventral tegular projection ( Fig. 5F–G ), while in H. zarate sp. nov., the ventral tegular projection is elongated and narrow ( Fig. 7C ); in H. cajuata sp. nov., the ventral tegular projection is wide and square ( Fig. 10C–D ); in the other species of the group, the ventral tegular projection is short and rounded ( Figs 3C–D , 6E , 7C , 9C , 10D ). Females of Hatitia riveti differ from those of other species of the yhuaia group by the epigynal plate with very enlarged lateral lobes across its entire length ( Figs 4F , 5L ), while in the other species of group, the lateral lobes are narrowed in the anteromedian region ( Figs 1H , 3H , 6I , 7F , 8F ; 10I ).
