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 ).
