Figs 83–88 View FIGURES 83–85 View FIGURES 86–88 , 90 View FIGURES 89–90

Type material. Holotype: PERU: Huanuco: ♂, ACP Panguana, Rio Yuyapichis (‑9.6167, ‑74.9333), 20 September– 7 October 2013, F. Wachtel & E.‑G. Burmeister leg. ( MUSM) GoogleMaps . Paratype: 1♂, same locality as holotype, October 2010, E. Diller leg. ( MUSM) GoogleMaps .

Etymology. The specific name refers to the type locality; noun in apposition.

Diagnosis. Males of S. yuyapichis spec. nov. resemble those of S. kaiabi spec. nov. ( Figs 13–15 View FIGURES 13–18 ) and S. punicea ( Figs 45–47 View FIGURES 45–50 ) by the palps with embolus arising from tegulum at 4 o’clock position ( Fig. 84 View FIGURES 83–85 ). They are distinguished from both species by the embolus base with a retrolateral swing, extending beyond retrocymbial margin ( Fig. 84 View FIGURES 83–85 ) (not extending beyond retrocymbial margin in S. kaiabi spec. nov. and S. punicea ). Females are unknown.

Description. Male (holotype): Total length 13.9. Prosoma: 6.6 long, 6.4 wide. Opisthosoma: 7.0 long, 4.3 wide. Eyes: diameters: 0.55, 0.46, 0.35, 0.45; interdistances: 0.30, 0.07, 0.55, 0.56, 0.27, 0.15. Legs: I: 35.5 (9.9, 3.5, 9.2, 10.3, 2.6); II: 37.8 (10.6, 3.6, 10.1, 10.8, 2.7); III: 26.9 (8.3, 3.0, 6.5, 7.1, 2.0); IV: 29.8 (9.0, 2.7, 7.4, 8.4, 2.3). Spination follows the generic pattern except tibia I: d1-0-1; tibia II: d0-0-1. Palp: PTA triangular, as wide as long; RTA two times longer than wide, slightly rounded at tip (in ventral view); subtegulum visible prolaterally in ventral view; tegulum roughly rectangular; conductor four times longer than wide, surpassing anterior margin of alveolus by half its length ( Figs 83–88 View FIGURES 83–85 View FIGURES 86–88 ).

Female: Unknown.

Variation. Males (n = 2): total length 13.9–14.9; prosoma length 6.5–6.6; femur I length 9.5–9.9.

Distribution. Only known from the type locality ( Fig. 90 View FIGURES 89–90 ).
