Type material. Male holotype from Jaboticabal  (21 ° 15 ’ 18 ”S; 48 ° 19 ’ 19 ”W), São Paulo, Brazil, 1979, L. Miller leg., deposited in MCZ.

Etymology. The specific name is a noun in apposition taken from the type locality.

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 10View FIGURE 10 D –F).

Eye diameters and interdistances: AME 0.18, ALE 0.14, PME 0.14, PLE 0.14; AME –AME 0.02, AME –ALE 0.04, PME –PME 0.16, PME –PLE 0.1, ALE –PLE 0.02. Chelicerae 1.9 long, with four promarginal teeth and five retromarginal denticles. Leg measurements: Leg I—femur 3.3 / patella 1.5 / tibia 4.2 / metatarsus 4.0/ tarsus 1.6 / total 14.6; II— 3.3 / 1.4 / 3.4 / 3.1 / 1.0/ 12.2; III— 2.4 / 1.0/ 1.6 / 2.5 / 0.7 / 8.2; IV— 3.5 / 1.2 / 3.1 / 4.2 / 1.0/ 13.0.

Palp: conductor of Anyphaeninae elongated; median apophysis long and curved in the apex ( Figs 10View FIGURE 10 A –F). Abdomen: length 4.1, epigastric furrow 0.8 from tracheal spiracle, spiracle 2.5 from base of spinnerets.
