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 211322View Materials), 1 male ( IBSP 211320View Materials) and 1 female ( IBSP 211323View 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 14–16View 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, 50View 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, 52View 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. IV – femur d1-1-1p; tibia d1-2-0, p0-1-1, r0-0-1, v1-2 -2; metatarsus d0-1r-0,p1-0-1, r0-0-1, v0-1p-2. Palp: femur with two dorsal spines, one median and one posterior; embolar insertion between 9–12 o’clock position, near median apophysis ( Figs 49, 50View 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. 75View FIGURES 75).
