Tupigea cantareira n. sp.

( Figs. 29–40 )

Tupigea sp.2 : Astrin, Huber, Misof & Klütsch 2006: 444.

Types. Male holotype from Parque Estadual da Cantareira (23° 25’ S; 46° 37’ W), São Paulo, São Paulo, Brazil, 02–07.II.2005, F. Yamamoto col. with pitfall traps, deposited in IBSP 60680. Female paratype, same data as holotype .

Etymology. Named after the type locality. The specific name is a noun in apposition.

Diagnosis. Males are distinguished from congeners by the shape of procursus ( Figs. 34–36 ), the round ventral apophysis on the palpal femur ( Fig. 34 ) and five pointed apophyses on the chelicerae ( Figs. 31–33 ). Females are distinguished by two large piriform internal structures, visible by transparency in ventral view, with the shape of two half-moons ( Figs. 38; 40 ).

Description. Male (Holotype). Total length 1.9, carapace width 0.8; leg I: 10.7 (2.7 + 0.1 + 2.9 + 3.6 + 1.4), tibia II: 1.8, tibia III: 1.5, tibia IV: 1.9, tibia I L/d: 29. Habitus as in figs. 29–30. Carapace with a darker stripe in the thoracic groove; sternum light ochre. Distinct thoracic groove. Eight eyes, AME very small ( Fig. 29 ); distance PME–ALE about 57% of PME diameter. Chelicerae light brown with five pairs of small pointed apophyses ( Figs. 31–33 ). Palps as in figs. 34–37. Coxa without retrolateral apophysis ( Fig. 34 ). Femur proximally with a rather rounded retrolateral apophysis ( Fig. 34 ) and a rounded ventral projection. Procursus straight and very simple, with a dorsal membranous portion at the tip ( Figs. 35–36 ). Bulb with sclerotized distal apophysis and prolateral membranous semitransparent small projection ( Fig. 37 ). Legs light brown; without spines or vertical hairs. Tarsus I with approximately 24 pseudosegments. Opisthosoma globular, pale green with some lateral dark spots ( Figs. 29–30 ).

Female (Paratype). Total length 1.8, carapace width 0.6; leg I: 6.4 (1.6 + 0.2 + 1.7 + 2.1 + 0.8), tibia II: 1.0, tibia III: 0.8, tibia IV: 1.1, tibia I L/d: 21. Habitus as in figs. 29–30. In general very similar to male. Tarsus I with approximately 14 pseudosegments. Epigynum dark brown, very simple, slightly elevated, with a relatively large membranous area between epigynum and post-epigynal plates ( Fig. 38 ). Two large internal structures are visible in dorsal view ( Fig. 39 ) and in ventral view by transparency, appearing like two half-moons ( Fig. 38 ). In some specimens these internal structures are visible through the membranous area ( Fig. 40 ), showing the piriform shape.

Variation. Seven males: carapace width 0.7–0.9; tibia I: 2.6–2.9. Male cheliceral apophyses vary slightly in size and position. Ten females: carapace width 0.6–0.7; tibia I: 1.7–1.9. The two large internal epigynal structures are exposed in some specimens.

Other material examined.
