Types. Male holotype from Fazenda Ranchinho da Roça , Petrópolis (22°30’18”S; 43°10’44’W), Rio de Janeiro, Brazil, 08–15.II.2000, Equipe Biota leg., deposited in IBSP 139930. Female GoogleMaps   paratype from Parque Estadual da Serra dos Órgãos, Teresópolis (22°24’34”S; 42°57’57”W), Rio de Janeiro, Brazil, 18–22.III.2001, Equipe Biota leg., deposited in IBSP 139561 GoogleMaps   .

Other material examined. Only the types.

Etymology. The specific epithet is a toponymic in apposition and refers to the type locality of the paratype.

Diagnosis. Males of Patrera teresopolis   n. sp. resemble those of P. opertanea   by the retrolateral tibial apophysis short, curved in the apex in male palp and atrium short in the epigynum (as in Figs 14C–F View FIGURE 14 , 15A–C View FIGURE 15 ), but differs by the apical median apophysis and tibial retrolateral apophysis short, truncated at tip and with basal tegular protuberance in the male palp ( Figs 25C–E View FIGURE 25 , 26A, B View FIGURE 26 ). Females are diagnosed by the subtriangular hood and copulatory ducts forming a triangle next to lateral borders in the female epigynum ( Figs 25F, G View FIGURE 25 , 26C, D View FIGURE 26 ).

Description. Male (Holotype, IBSP 139930). Carapace and legs orange; chelicerae yellow; labium and endites orange. Abdomen gray with spots dorsal; ventrally cream ( Fig. 25A View FIGURE 25 ). Total length 4.8, carapace length 2.1, width 1.8. Clypeus height 0.06. Eye diameters and interdistances: AME 0.06, ALE 0.10, PME 0.10, PLE 0.10; AME– AME 0.02, AME–ALE 0.04, PME–PME 0.10, PME–PLE 0.08, ALE–PLE 0.04.

Abdomen: length 2.6, epigastric furrow 0.9 from tracheal spiracle, spiracle 1.0 from base of spinnerets. Palp: tibia shorter cymbium, slightly curved; cymbium oval; tegulum oval, with sperm duct forming a basal inverted “U-shaped” course; tegular projection short, adjacent to the tip of embolus; short and curved median apophysis; slender prolateral embolus, originating at the base of the tegulum ( Figs 25C–E View FIGURE 25 , 26A, B View FIGURE 26 ).

Female (IBSP 139561). Carapace yellow. Chelicerae yellow; labium, endites and sternum yellow. Legs yellow, darkest from tibiae to tarsi. Abdomen yellow; ventrally yellow ( Fig. 25B View FIGURE 25 ). Total length 7.7, carapace length 2.8, width 2.15. Clypeus height 0.08. Eye diameters and interdistances: AME 0.08, ALE 0.12, PME 0.12, PLE 0.14; AME–AME 0.02, AME–ALE 0.04, PME–PME 0.14, PME–PLE 0.10, ALE–PLE 0.04. Chelicerae 1.3 long, four promarginal teeth, six retromarginal denticles.

Abdomen: length 4.6, epigastric furrow 1.7 from tracheal spiracle, spiracle 2.0 from base of spinnerets. Epigynum: lateral borders not connected distally; small, subtriangular atrium; internally with coiled copulatory ducts; seminal receptacles globose in the posterior region; spermathecae oval and fertilization ducts short, curved, basal ( Figs 25F, G View FIGURE 25 , 26C, D View FIGURE 26 ).
