Males of S. punicea resemble those of S. kaiabi spec. nov. ( Figs 13–15 ) and S. yuyapichis spec. nov. ( Figs 83–85 ) by the palp with embolus arising from tegulum at 4 o’clock position ( Fig. 46 ). They are distinguished from those of S. kaiabi spec. nov. by the RTA roughly the same width throughout ( Fig. 47 ), tegulum oval and conductor surpassing the anterior margin of alveolus by half its length ( Fig. 46 ) (RTA tapering and distally pointed, tegulum rounded and conductor barely surpassing the anterior margin of alveolus in S. kaiabi spec. nov. ); from those of S. yuyapichis spec. nov. by the embolus base not extending beyond retrocymbial margin in ventral view ( Fig. 46 ) (embolus base with a retrolateral swing, extending beyond retrocymbial margin in S. yuyapichis spec. nov. ). Females resemble those of S. nanay spec. nov. ( Figs 35–37 ) by the epigyne with MS diamond-shaped posteriorly ( Fig. 48 ). They are distinguished by the MS less than 1.5 times longer than wide with rounded CO ( Fig. 48 ) and vulva with internal ducts tightly twisted ( Figs 49–50 ) (MS more than 1.5 times longer than wide with elliptical CO and internal ducts loosely twisted in S. nanay spec. nov. ). Description. Male (IB 165051): Total length 13.6. Prosoma: 5.9 long, 5.5 wide. Opisthosoma: 7.2 long, 4.5 wide. Eyes: diameters: 0.50, 0.40, 0.30, 0.39; interdistances: 0.30, 0.04, 0.45, 0.45, 0.30, 0.20. Legs: I: 34.6 (9.7, 3.2, 9.7, 9.8, 2.2); II: 37.7 (10.9, 3.3, 10.4, 10.5, 2.6); III: 26.3 (8.0, 2.6, 6.9, 6.8, 2.0); IV: 29.9 (8.9, 2.5, 7.9, 8.4, 2.2). Spination follows the generic pattern except patella I: p0; tibiae I–II: d1-0-1; tibia IV: d0; metatarsus IV: r1-1-1. Palp: RTA roughly as wide as long, concave in ventral view; PTA triangular, slightly longer than wide; subtegulum visible prolaterally in ventral view; conductor three times longer than wide ( Figs 45–47 , 51–53 ). Redescription. Female (IBSP 7362): Total length 18.3. Prosoma: 7.5 long, 8.5 wide. Opisthosoma: 9.8 long, 8.5 wide. Eyes: diameters: 0.54, 0.40, 0.38, 0.48; interdistances: 0.40, 0.16, 0.80, 0.74, 0.40, 0.40. Legs: I: 31.6 (9.3, 3.7, 8.1, 8.4, 2.1); II: 33.3 (9.7, 3.7, 8.8, 8.8, 2.3); III: 23.4 (7.0, 3.0, 6.0, 5.6, 1.8); IV: 27.4 (8.4, 3.0, 7.0, 6.8, 2.2). Spination follows the generic pattern. Epigyne: EF as wide as long; MAB short; TP almost 2–3 times wider than long; LL touching posteriorly; ( Figs 48 , 54 ). Vulva: FW laterad; GP small, rounded, arising from duct at second turn; SP spherical; FD mediad, then laterad with subdistal turn ( Figs 49–50 , 55 ). Variation. Males (n = 4): total length 13.0–15.8; prosoma length 5.9–6.6; femur I length 8.5–10.0. Females (n = 6): total length 18.3–21.8; prosoma length 7.5–8.2; femur I length 8.0–9.3. Distribution. Iquitos in Eastern Peru and Manaus in central Amazonia, Brazil ( Fig. 89 ).
