Figs 1–7 , 36–37 Type­material : Male holotype (MZSP­17753), Brazil , Mato Grosso, Juruena (Amazonian Rain Forest, 12°51´S , 58°56´W ), 7.–18.VI.1997 , G. Skuk leg. Diagnosis : The new species is similar to P. evelianeae (Soares & Soares, 1978) by the presence of a dorsal row of acute tubercles on male patella IV to basal third of tibia IV. It differs from P. evelianeae by the presence of a prolateral row of acute tubercles on distal half of male tibia IV and by the absence of a wide eminence on anterior margin of dorsal scute. Etymology : “Folia de Reis” is a popular Brazilian religious festival in which people go from home to home, chanting and playing instruments, held between Christmas and January 6th . The singers perform religious themes about the birth of Jesus, and they are dressed with colored­striped clothes adorned with small pieces of mirror. The specific epithet is a noun in apposition. Description of male ( holotype ): Measurements: Dorsal scute length 4.4; prosoma length 2.0; dorsal scute width 3.8; prosoma width 3.6; interocular distance 2.6; chelicera: II 5.1; III 2.2; pedipalpus 16.5; leg I 21.0; II 38.5; III 28.5; IV 36.5. Dorsum ( Figs 1–2 ): Prosoma with low anterior eminence carrying 9 small tubercles. Ocularium smooth. Lateral margin with tubercles from eyes to groove II. Area III with 2 parallel spines. Venter: Coxa I with 1 median row of 5 tubercles, 2 apical; II with 1 median row of 6 tubercles; III and IV irregularly minutely tuberculated. Free sternites I–III with a row of minute granules. Anal plate irregularly minutely granular. Chelicera: Swollen. Segment I smooth; II with finger carrying 1 wide lamina and 2 small teeth; III with 3 subapical teeth (basal one widest). Pedipalpus ( Figs 3–4 ): Coxa with large dorso­anterior apophysis and 1 basal posterior tubercle. Trochanter with 1 ventral tubercle. Femur with 1 ventro­basal tubercle. Tibia mesal IIiIi (2=4>1>3=5), ectal IIiIi (4>1>2>5>3). Tarsus mesal IiIiii (1=3>5>2>4>6), ectal Iiiii (1>4;2=5). FIGURES 1–7. Protimesius foliadereis , sp. nov , male holotype. 1 Dorsal view of body. 2 Lateral view of body. 3–4 Right palpus (3 ectal, 4 mesal view). 5–7 Proximal segments of leg IV (5 dorsal, 6 ventral and 7 lateral view of patella and tibia). Scale bars: 1 mm. Legs ( Figs 5–7 ): Coxa I with 2 anterior and 1 posterior tubercles; II with 2 posterior tubercles (1 fused with another of coxa III); III with 1 tubercle fused with other of coxa IV; IV minutely tuberculated. Trochantera I and II with 3 ventral tubercles; III and IV with 2 ventral tubercles. Femur IV with prolatero­apical row of 5 tubercles; retrolateral row of 15 tubercles on distal third. Patella IV with dorsal row of 8 tubercles increasing in size apicad, 1 large ventro­apical tubercle. Tibia IV with 1 row of tubercles from ventral to mesal (increasing in size apicad); 1 prolateral row on distal 2/3, increasing in size apicad (apical tubercle trifid); 7 dorso­basal tubercles. Tarsal segmentation: 8, 19, 7, 8. Penis ( Figs 36–37 ): Ventral plate with lateral and distal margin almost straight, 3 curved distal setae, no intermediary pair, 4 basal pairs of straight setae; with dorsal process; stylus swollen apically. Color: Mostly brown, with minute dark brown spots all over body and legs. Chelicerae (fingers darker) and tibia IV reddish brown. Female unknown.
