Group yhuaia

Diagnosis

The yhuaia group differs from the canchaque group by the palp lacking a tegular projection and endites with external lateral margin furrowed and by the female epigynum with hood positioned in the anterior region or absent ( Figs 1E–I , 3A–H , 4C–G , 5E–L , 6E–I , 7C–G , 8C–G , 9B–E , 10C–J ).

Composition

Hatitia yhuaia , H. riveti , H. sericea , H. zarate sp. nov., H. winayhuayna sp. nov. and H. cajuata sp. nov.
