Roeweria garrincha sp. n.

( Figs. 1 C–D, 2G–H, 3D–F, 4, 8)

Type material. BRAZIL, São Paulo: Male holotype (MZSP-30358), Cananéia (Serra do Itapitangui, road to Ariri, 24°59´18”S, 48°01´05”W), 2.II.2006, M.B. da Silva leg. One female paratype (MZSP-30359), same data as holotype.

Etymology. The specific name honors one of the Brazilian Soccer icons, Garrincha (nickname of Manoel dos Santos, 1933–1983), the “Angel of crooked legs”, and refers to the slight curvature of male leg IV.

Diagnosis. R. garrincha resembles the other two species of Roeweria by the stylus of the penis which is long, narrow and with two apical lateral projections, male coxa IV with internal and curved external apophyses. Resembles R. virescens by the color pattern, with tubercles of dorsal scutum surrounded by yellow patches and by the absence of large dorsal acute tubercles on the patella and tibia IV. Roeweria garrincha sp.

n. differs from the other species by the presence of ventral process on penis, very large ventral apophyses on apex of femur and patella IV and male coxa IV external apophysis with a basal tubercle.

Description of the male holotype. Dorsum ( Fig. 1 C,D): Measurements: Dorsal scutum length 5.7; maximum width 5.8; prosoma length 2.2; maximum width 2.8. Anterior margin of dorsal scutum with three tubercles on each side, two central. Ocularium high, with two pointed and divergent apophyses, slightly curved frontwards; two tubercles on base of spines ( Fig. 1 D). Prosoma with six tubercles between ocularium and groove I. Area I divided, with 8–10 tubercles scattered on each side (1 pair large); II with 19 small tubercles; III with 15 tubercles and one large, blunt pair of apophyses; IV with eight tubercles. Lateral margin with tubercles concentrated between areas II–IV. Posterior margin with 11 tubercles. Free tergite I with a row of 11 tubercles; II with 10 (central pair high and pointed); III with six (central pair high and pointed). Anal operculum with minute and scattered tubercles.

Venter: Coxa I with a median row of seven tubercles, two apical and three basal tubercles; II with a median row of eight tubercles; III–IV irregularly covered with minute tubercles; free sternites I–III with a row of minute tubercles; anal plate irregularly tuberculated.

Chelicera: Segment I with four tubercles on bulla; II with five teeth; III with seven teeth.

Pedipalp: Trochanter with two dorsal tubercles, one ventral tubercle. Femur with subapical prolateral setae, with five ventral tubercles (basal most largest). Patella smooth. Tibia ectal and mesal IiIi. Tarsus mesal IiIi, ectal IIi, with a pair of medio-ventral rows of microsetae.

Legs ( Fig. 3 D–F): Coxa I with one anterior tubercle and one directed to II; II with one large tubercle behind anterior ozopore, two convergent between two ozopores, one directed to III; III with one tubercle fused with another of II and one retrolateral tubercle directed to coxa IV. Femora–tibiae I–III with six longitudinal rows of small tubercles. Coxa IV covered with tubercles, one dorsal external pointed apophysis with one basal tubercle on retrolateral face, internal apophysis unique and much smaller than external one. Trochanter IV twisted retrolaterally, with one prolateral-basal large and rounded tubercle, one retrolateral-apical acute tubercle, with scarce, minute dorsal tubercles, enlarged and abundant ventral tubercles. Femur IV arched dorsad, with three basal slightly enlarged tubercles (one dorsal, one retrolateral and one between them), two ventral rows of tubercles, subapically with one large retrolateral spine and one prolateral apophysis, apically with one prolateral blunt apophysis. Patella IV covered by tubercles, ventrally with one large and retrolaterally curved apophysis (size similar to patella length). Tibia IV with two ventral rows of tubercles (retroventral row with enlarged and pointed tubercles), one retrolateral row of enlarged, pointed tubercles, one dorsal row of tubercles and small tubercles scattered on dorsal and prolateral faces. Tarsal segmentation: 6(3), 11(3), 7, 8. Basitarsus I slightly swollen.

Penis ( Fig. 8 ): Ventral plate hexagonal, distal margin straight, with four pairs of basal setae, three pairs of long, straight distal setae and one pair of median small setae. Stylus long and narrow, with two apical lateral projections, ventral process much shorter and thinner than stylus, with serrated apex.

Coloration. Yellow-greenish with minute black spots, tubercles of dorsal scutum surrounded by yellow patches. Apophyses of ocularium and area III black. Ocularium and chelicerae black reticulate. Apex of coxa to patella IV reddish.

Female (paratype; Fig. 2 G,H): The characteristics similar to the male were omitted. Dorsal scutum length 5.1; maximum width 5.0; prosoma length 1.9; maximum width 2.7. Anterior margin of dorsal scutum with 4– 5 small tubercles on each side, frontal hump smooth. Ocularium high, with two pointed and divergent apophyses, slightly curved frontwards; two tubercles on base of apophyses ( Fig. 2 G,H). Prosoma with seven tubercles behind ocularium. Lateral margin with tubercles from groove II–IV. Area I with 11–13 tubercles on each side (one large on each side); II with 22 tubercles; III with two large apophyses with rounded apex, 17 tubercles; IV with one row of nine tubercles. Posterior margin with 16 tubercles. Free tergite I with a row of 14 tubercles (central pair high and pointed); II with 13 (central pair high and pointed); III with 10. Coxa IV with one external pointed and oblique apophysis, internal apophysis absent. Femur IV with two ventral rows of tubercles (enlarged in ¼ apical). Patella IV tuberculate, with two ventral rounded enlarged tubercles. Tibia IV with two ventral rows of tubercles of similar size. Tarsal segmentation: 6(3); 10 (3); 7; 7.
