Pseudopachylus alticola ( H. Soares, 1945) comb. nov.

Olynthus alticola H. Soares 1945: 247 , fig. 4 “ Olynthus alticola ”: Kury 2003: 200

Type material. Ψ holotype (HS 100), Brazil, São Paulo, Alto da Serra, examined.

Other material examined. 1 ♂ ( MZSP 18891), Brazil, São Paulo, Santo André, Alto da Serra (coordinates ­25.3500, ­ 48.9167), 27.viii. 1999, R. Pinto da Rocha et al. leg.

Diagnosis. Eye mound with thick straight spine instead of typical Pseudopachylus hook, this spine is clearly thicker at base, giving an arched aspect to it in dorsal view. Male coxa IV ventrally with strong apophysis on retrolateral border, apophysis with a subapical secondary lobe. Male trochanter IV ventrally with blunt stout apophysis on retrolateral part. Tarsal formula: 5 (3)/ 7 (3)/ 5 / 5. Closest to the new species described below, specially by the structure of the eye mound.

Distribution. BRAZIL. São Paulo. Santo André: Estação Biológica do Alto da Serra, 850 m. WWF Ecoregion: NT0160 (Serra do Mar coastal forests). Biome: Tropical & Subtropical Moist Broadleaf Forests. Known only from the type locality.

Comments. Olynthus is currently a junior synonym of Spinopilar Mello­Leitão 1940 ( Kury 2003) , but Olynthus alticola is not specially closely related to its type species. Hitherto only a female was known, but now, with a comparative study of the characters of the Tricommatinae for a revision and the discovery of a male from the type locality, important diagnostic characters can be appreciated, which allow to relate Olynthus alticola with the species of Pseudopachylus : 1) male femur IV straight and much elongate, entirely smooth and unarmed (shorter and weakly armed in Spinopilar ), 2) eye mound with stout spiniform process (with small tubercle in Spinopilar ), 3) male trochanter IV with retrolateral subbasal small procurved apophysis (subdistal strong recurved apophysis in Spinopilar ), 4) stigmata placed on a prominent mound (sessile in Spinopilar ), 5) free sternite I with lobe projecting against coxal apophysis (free sternite I without lobe), 6) male coxa IV small, reaching at most mid scutal area II (male coxa IV large, reaching mid to end of scutal area IV).
