Figs 8–9, 15

Diagnosis

Males of Hatitia winayhuayna 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 rugose, sickle-shaped, and elongated retrolateral tibial apophysis and a prolaterally pointed cymbial projection (Figs 8C–E, 9B–E). Females of Hatitia winayhuayna resemble those of H. yhuaia, H. riveti, and H. cajuata sp. nov. by the short hood and wide copulatory ducts (Figs 1H–I, 3H, 4F–G, 5L, 10I–J), but differ by the epigynal plate being Y-shaped with the curved extremity of the lateral lobes in a horizontal position in the anterior region (Fig. 8F–G). The epigynal plate is T-shaped with laterally elongated lateral lobes at the extremity in H. yhuaia (Figs 1H, 3H); the epigynal plate has lateral lobes distant from each in the anterior region and a large atrium in H. riveti (Figs 4F, 5L; see Dupérré 2023: fig. 12c), and the epigynal plate is U-shaped with straight lateral lobes and a wide atrium in H. cajuata (Fig. 10I).

Etymology

The specific name is related to the type locality, the word comes from Quechua and can be translated as “forever young”. For the natives of the region, this locality seems to connect in a special way with nature, making you feel alive or young forever.
