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 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 .

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 , 15A–C ), 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 , 26A, B ). Females are diagnosed by the subtriangular hood and copulatory ducts forming a triangle next to lateral borders in the female epigynum ( Figs 25F, G , 26C, D ).

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 , 26A, B ).

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 ).

Chelicerae 1.3 long, four promarginal teeth, six retromarginal denticles.
