Teudis hirsutus Mello-Leitão, 1938: 316, figs 6, 7 (male holotype from Corumbataí 22°13’12”S; 47°37’33”W, São Paulo, Brazil, 20.XI.1935, S. Burian leg., deposited in IBSP 3460, examined).
Xiruana hirsuta: Brescovit, 1997: 104.
Diagnosis. Males of X. hirsuta resembles those of X. gracilipes by the conical extremities of the branches of the retrolateral tibial apophysis and by the subtriangular median tibial apophysis, but differ from this species by the male palp with conductor of Anyphaeninae flattened at the tip and with a retrolateral keel, and the short extremities of the branches of the retrolateral tibial apophysis (Figs 3 A–F). Females differ from congeners by the epigynal plate elongated, with the anterior border with the same width as the posterior border (Fig. 3 G).
