Figs 22 –28View FIGURES 22 – 28, 42– 43View FIGURES 36 – 45

Type­material: Male holotype (MZSP­ 14239), Brazil, Pará, Ananindéua (Km 13, BR­ 316, Cerrado, 1 ° 22 ´S, 48 ° 23 ´W), 22.VIII. 1976, R.F. Silva leg.

Diagnosis: This species is closely related to P. laevis Sørensen, 1932  according to penis shape, high numbers of setae on lateral side of ventral plate, and stylus without dorsal process. It can be distinguished from all other members of the genus by having 1 ventral row of tubercles on male femur IV.

Etymology: “ Cirio  de Nazaré” is a procession that takes place in the Brazilian state of Pará, where this species was collected. In this religious celebration the image of “Nossa Senhora de Nazaré” is carried from the main church of Belém on a boat and in a street procession to a sanctuary in the center of the city. The specific epithet is a noun in apposition.

Description of male (holotype):

Measurements: Dorsal scute length 4.7; prosoma length 2.4; dorsal scute width 3.6; prosoma width 3.6; interocular distance 2.7; chelicera: II 4.7; III 2.1; pedipalpus 16.5; leg I 19.5; II 36.0; III 27.5; IV 34.0.

Dorsum ( Figs 22–23View FIGURES 22 – 28): Anterior margin with 5–8 tubercles on each side. Prosoma with 2 large and several small tubercles. Ocularium smooth, with small tubercles surrounding it. Lateral margin with some small tubercles distributed from eyes to groove I. Area I with 2–3 tubercles on each side; II smooth; III with two slightly divergent backward directed spines. Posterior margin minutely granular.

Venter: Coxa I with 1 median row of 6–7 tubercles, 3–4 anterior tubercles, 4–6 posterior tubercles, 4 apical tubercles; II with median row of 8–10 tubercles, 1–3 anterior tubercles, 2 posterior tubercles, 4 apical tubercles; III with median row of 8 tubercles, 5–6 anterior tubercles, 5–6 posterior tubercles; IV irregularly tuberculate, 3–4 apical tubercles. Posterior margin and free sternites with a row of minute granules. Anal plate smooth.

Chelicera: Segment I with 1 small distal tubercle; II with finger carrying 1 large basal tooth and 3 small distal teeth; III with 1 large and rounded basal tubercle and 4 small distal teeth.

Pedipalpus ( Figs 24–25View FIGURES 22 – 28): Coxa with 2–5 ventral, 4–5 dorsal (mesal one largest) tubercles. Trochanter with 1 dorsal and 2 ventral tubercles. Femur slightly curved, with 1 ventrobasal tubercle. Tibia mesal IIiIi (4> 1> 2> 5> 3), ectal IIiIi (1> 2> 4> 3 = 5). Tarsus mesal Iiii (1> 2 = 3 = 4), ectal IiIiIi (3> 1> 5> 2> 4 = 6).

Legs ( Figs 26–28View FIGURES 22 – 28): Coxa I with 3 tubercles; II with 1 anterior tubercle and 1 posterior tubercle fused with one of coxa II; IV small granular. Trochanter I with 3 ventral tubercles (basal one largest); II and III with 3 ventral tubercles (distal one largest); IV with 1 large dorso­apical tubercle. Femur IV with row of 24 ventral tubercles. Patella IV with 1 large postero­distal tubercle. Tibia IV straight, smooth. Tarsal segmentation: 8, 19, 6, 7.

Penis ( Figs 42–43View FIGURES 36 – 45): Ventral plate with lateral and distal margin concave, 4–5 curved pairs of distal setae, 1 intermediary pair, 12 pairs of straight setae on base of ventral plate and apex of truncus; no dorsal process; stylus swollen apically.

Color: Dorsal scute and coxae of legs reddish brown. Anterior part of prosoma, chelicera, pedipalpal tibia and tarsus reticulate. Pedipalpal coxa to patella and legs I –III yellowish brown. Leg IV reddish brown.

Female unknown.
