Type material. Male holotype from Brazil, São Paulo, Ubatuba (Fazenda Angelim), [23°24'5.55"S 45°3'51.26"W], 23–29 July 2001, C.A. Rheims et. al. leg., deposited in IBSP 211321. Paratypes with same data as holotype: 1 male ( IBSP 211322 View Materials ), 1 male ( IBSP 211320 View Materials ) and 1 female ( IBSP 211323 View Materials )   .

Etymology. The specific name is a noun in apposition and refers to the type locality.

Diagnosis. Males of P. angelim   sp. nov. resemble those of P. doisirmaos   sp. nov. and P. bocaina   sp. nov. in having six eyes ( Figs 14–16 View FIGURES 13–18 ). They differ from P. bocaina   sp. nov. in having PME completely formed and male palps with rounded tegulum (ovoid in P. bocaina   sp. nov.), and from P. doisirmaos   sp. nov. in having male palps with median apophysis hook-shaped (large and twisted at base in P. doisirmaos   sp. nov.) and RTA with robust base and constricted tip (triangular, without constriction in P. doisirmaos   sp. nov.) ( Figs 49, 50 View FIGURES 49–52 ); females are distinguished from those of the other known species of the genus by the epigyne with posterior margin of atrium semicircular forming a hood ( Figs 51, 52 View FIGURES 49–52 ).

Description. Male (holotype). Total length: 1.86. Carapace 0.80 long, 0.62 wide; abdomen 0.91 long, 0.55 wide; sternum 0.53 long, 0.47 wide; spinnerets ALS 0.21 long, 0.075 wide. Six eyes arranged in two triads. AME absent. Eye diameters and interdistances: ALE 0.048; PLE 0.035; PME 0.032; ALE–ALE 0.032; PLE–ALE contiguous; PME–ALE contiguous; PME–PLE 0.024; PME–PME 0.032. Chelicerae 0.27 long; 6 retromarginal teeth and 4 promarginal teeth. Leg formula 4123; measurements: I: 2.12 (0.58, 0.34, 0.47, 0.39, 0.34); II: 1.97 (0.56, 0.31, 0.41, 0.35, 0.34); III: 1.75 (0.35, 0.32, 0.34, 0.25, 0.49); IV: 2.36 (0.62, 0.32, 0.50, 0.48, 0.44). Leg spination: I – femur d1-1-0, p0-0-1; tibia v2-2 -0; metatarsus v0-2-0.II – femur d1-1-0; tibia v1-1 -0; metatarsus v0- 1-0.III – femur d1-1-0; tibia d1p-1-0, p0-0-1, r0-0-1, v0-2-2; metatarsus p0-1-1, v0-2- 3.

Palp: femur with two dorsal spines, one median and one posterior; embolar insertion between 9–12 o’clock position, near median apophysis ( Figs 49, 50 View FIGURES 49–52 ).

Female: (paratype). Total length: 2.25. Carapace 0.82 long, 0.65 wide; abdomen 1.12 long, 0.75 wide; sternum 0.57 long, 0.5 wide; spinnerets ALS 0.13 long, 0.083 wide. Six eyes arranged in two triads. AME absent. Eye diameters and interdistances: ALE 0.055; PLE 0.03; PME 0.03; ALE–ALE 0.04; PLE–ALE 0.01; PME–ALE 0.01; PME–PLE 0.02; PME–PME 0.032.

Variation. Total length (2 males): 1.86–1.87.

Distribution. São Paulo, Brazil ( Fig. 75 View FIGURES 75 ).
