Etymology. The specific name is a noun in apposition taken from the typelocality.
Diagnosis. Males of Xiruana jaboticabal n. sp.resemble those of X. pocone n. sp.by the palp with an extremely long base of conductor of Anyphaeninae, distant from the ventral tegular process, but differ by the anterior and posterior branches of the retrolateral tibial apophysis being extremely separated, and by the inconspicuous rounded median tibial apophysis ( Figs 10D–F).
