Hatitia yhuaia Brescovit, 1997: 115, figs 309–314.

Diagnosis

Males of Hatitia yhuaia differ from those of other species of the yhuaia group by having palps with a discrete median tibial apophysis and a short retrolateral tibial apophysis on the tibia (Figs 1E–F, 3E–G), while in the other species of the group, the median tibial apophysis is conspicuous, and the retrolateral tibial apophysis is elongated (Figs 4C–E, 5G–H, 6E–F, 7C, E, 8C, E, 9D–E, 10C–D, G), with the exception of H. sericea, which does not exhibit a median tibial apophysis (Fig. 6F–G). Females of Hatitia yhuaia differ from those of other species of the yhuaia group by the T-shaped epigynal plate with laterally elongated lateral lobes (Figs 1H–I, 3H). In H. riveti, the epigynal plate has lateral lobes attached anteriorly (Figs 4F–G, 5L; see Dupérré 2023: figs 12c–d); in H. sericea, the epigynal plate has narrow lateral lobes (Fig. 6I); in H. zarate sp. nov., the epigynal plate has cup-shaped lateral lobes and separate spermathecae (Fig. 7F–G); in H. winayhuayna sp. nov., the epigynal plate is Y-shaped with medially narrowed lateral lobes (Fig. 8F); in H. cajuata sp. nov., the U-shaped epigynal plate has straight lateral lobes and a wide atrium anteriorly (Fig. 10I–J).
