( Figs. 1–12 View FIGURE 1 View FIGURES 2–4 View FIGURES 5–8 View FIGURES 9–12 )

Pertica badia Simon 1903: 24 (Probably immature female holotype from Colonia Alpina, Serra dos Orgãos View in CoL , Rio de Janeiro [not São Paulo as in Simon’s label, see Paynter & Traylor Jr. (1991)], Brazil, deposited in the Muséum National d’Histoire Naturelle, Paris, number 19225, examined, epigynum detached and lost); Brignoli 1974: 256, figs. 1, 5; Platnick 1989: 2–4; Brescovit et al. 2002: 332; Platnick 2005.

Other material examined. BRAZIL. Rio de Janeiro: Nova Friburgo, Amparo, 1 male, 20.XII.1993, A.B. Kury leg. ( MNRJ); Teresópolis, Parque Nacional da Serra dos Órgãos, 2 females, 18–22.VIII.2001, Equipe Biota leg ( IBSP 50823 View Materials , 50824 View Materials ) .

Diagnosis. Segestrioides badia is easily distinguished from its Peruvian and Chilean congeners by the less hirsute body ( Fig. 1 View FIGURE 1 ), male palp with pear­shaped tegulum ( Figs. 2– 3 View FIGURES 2–4 ) and female epigynum with small bursa copulatrix and elongated anterolateral sclerotized plates, with basal area enlarged and rounded ( Fig. 4 View FIGURES 2–4 ).

Description. Male ( MNRJ). Carapace, sternum and chelicerae orange. Eye borders black. Labium and endites orange with white apex. Legs and pedipalps orange, except for articulations and coxae yellow. Abdomen completely greenish­gray, with transverse white bands on posterior third and cream colored spinnerets ( Fig. 1 View FIGURE 1 ). Total length 3.40. Carapace 1.60 long, 1.10 wide, very slightly hirsute, thoracic groove curved, strongly depressed, with six lateral thoracic furrows. Clypeus 0.22 high. Eye diameters: AME absent, PME 0.14, ALE 0.12, PLE 0.12. Chelicerae soldered together at base by a conspicuous white membrane ( Fig. 5 View FIGURES 5–8 ), with a translucent hyaline keel, a ventral gland mount with great number of pores ( Fig. 6 View FIGURES 5–8 ) and conspicuous prolateral stridulatory ridges ( Fig. 7 View FIGURES 5–8 ). Leg measurements: I: femur 1.60/ patella 0.50/ tibia 1.30/ metatarsus 1.10/ tarsus 0.70/ total 5.20; II: 1.40/ 0.40/ 1.10/ 1.00/ 0.60/ 4.60; III: 1.00/ 0.40/ 0.70/ 0.80/ 0.60/ 3.50; IV: 1.60/ 0.50/ 1.20/ 1.10/ 0.50/ 4.90. Tarsi I unbent, not pseudosegmented. Male palp with cymbium slightly excavated distally ( Fig. 2 View FIGURES 2–4 ), pear­shaped tegulum and wide, flattened, laminate embolus, without sclerites ( Figs. 2–3 View FIGURES 2–4 ). Male gonopore on distinct protuberance. Abdomen hirsute, but much less than in Chilean and Peruvian species.

Female ( IBSP 50823). Coloration pattern as in male. Total length 4.10. Carapace 2.00 long, 1.40 wide, thoracic groove and thoracic furrows inconspicuous. Clypeus 0.30 high. Eye diameters: AME absent, PME 0.14, ALE 0.12, PLE 0.12. Chelicerae as in male. Leg measurements: I: femur 1.50/ patella 0.50/ tibia 1.20/ metatarsus 1.00/ tarsus 0.70/ total 4.90; II: 1.50/ 0.50/ 1.10/ 0.90/ 0.70/ 4.70; III: 1.10/ 0.50/ 0.90/ 0.70/ 0.60/ 3.80; IV: 1.60/ 0.60/ 1.10/ 1.10/ 0.60/ 5.00. Trichobothria on metatarsi with elevated, smooth and rounded base ( Fig. 8 View FIGURES 5–8 ). Tarsus I with prolateral row of depressed glands, with oval median opening ( Fig. 9 View FIGURES 9–12 ) and dorsal row of slightly projected, oval sensilla, with slit openings ( Fig. 10 View FIGURES 9–12 ). Palpal femur with stridulatory pick short and stout, on rounded and projected socket ( Fig. 11 View FIGURES 9–12 ) and tarsus without claw, ending in acuminate pit ( Fig. 12 View FIGURES 9–12 ). Epigynum externally with semicircular sclerotizations, internally with small semicircular bursa copulatrix bearing pair of elongated anterolateral sclerotized plates ( Fig. 4 View FIGURES 2–4 ). Abdomen as in male.

Natural History. The specimens were collected on the ground, manually or with pitfall traps, in Atlantic Forest areas. The Serra dos Orgãos is located 1000m above sea level and is classified as “humid mountain tropical forest” ( Fernandes 1998; Barros 2000). The juvenile holotype was collected in an area ranging between 1000m and 1200m above sea level. Both areas are characterized by average temperatures of 17.8ºC at 1000m above sea level. This distribution suggests that this species is restricted to high montane areas of southeastern Brazil.

Distribution. Known from montane areas of the state of Rio de Janeiro, Brazil.
