Diagnosis. Males of Xiruana gracilipes  resemble those of X. hirsuta  by the conical extremities of the branches of the retrolateral tibial apophysis and the subtriangular median tibial apophysis, but differ from this species by the conductor of Anyphaeninae narrow and curved at the apex, without retrolateral projection, and by the long extremities of the branches of the retrolateral tibial apophysis ( Fig. 2View FIGURE 2 A). Females resemble X. cocha  n. sp. by the shape of the epigynal plate ( Fig. 14View FIGURE 14 C), but differ by the larger posterior border and internally by the thicker copulatory ducts and seminal receptacles with long ducts ( Figs 2View FIGURE 2 G, H).

Description. Male and female described by Brescovit (1997: 104).
