Type material. Holotype: ♂ from PERU: Loreto: Jenaro Herrera Province, Requena District, Centro de Investigaciones Jenaro Herrera (04°53’39.9”S, 73°39’01.9”W), 2 April 2013, C.A. Rheims & R. P. Indicatti leg. ( MUSM). GoogleMaps

Etymology. The specific name refers to Ucayali River, where the type locality is located; noun in apposition.

Diagnosis. Males of S. ucayali sp n. resemble those of S. urucu by the palp with conductor distally widened ( Fig. 32 View FIGURES 29−33 , Rheims 2010a: figs 34−35). They are distinguished from the latter species by the dRTA bearing two thornlike projections at tip (dRTA with single, hooked-shaped projection in S. urucu ) and by the embolus with basal projection partly membranous (all sclerotized in S. urucu ) ( Figs 23 View FIGURES 20−23 , 41 View FIGURES 38−42 ). Females are unknown.

Description. Male (holotype): Prosoma pale yellow with grayish black margins and marks between thoracic striae and two orange brown marks at the base of cephalic region extending towards PLE; margins flanked by long, black, needle-like setae; fovea and thoracic striae orange brown; eye area slightly more orange than rest of prosoma; eye borders black; clypeus pale yellow. Chelicerae pale yellow with pair of grayish black marks at base. Legs pale yellow with small grayish black spots at the base of setae and larger round marks at the base of spines. Palps pale yellow with round, grayish black marks at the base of femoral spines. Sternum cream colored with pale brown margins. Endites cream colored. Labium orange, distally cream colored. Opisthosoma pale gray. Dorsally with pair of round, muscular impressions on posterior half, white spots laterally and covered by orange setae. Ventrally with white spots laterally ( Figs 36−37 View FIGURES 34−37 ). Total length 6.0. Prosoma: 2.7 long, 2.8 wide. Opisthosoma: 3.2 long, 2.4 wide. Eyes: diameters: 0.18, 0.22, 0.16, 0.22; interdistances: 0.10, 0.02, 0.26, 0.26, 0.26, 0.26. Legs (2143): I: 23.6 (6.1, 1.6, 6.9, 6.5, 2.5); II: 26.0 (6.7, 1.7, 7.6, 7.5, 2.5); III: 16.3 (4.6, 1.2, 4.4, 4.5, 1.6); IV: 18.7 (5.0, 1.1, 4.8, 5.7, 2.1). Palp: vRTA small, triangular; dRTA laminar; DTA abruptly narrowed and curved at tip; conductor hyaline; embolus filiform, strongly curved prolaterally, with basal projection with pointed tip ( Figs 31−33 View FIGURES 29−33 , 40−42 View FIGURES 38−42 , 65 View FIGURES 57−66 , 72 View FIGURES 67−76 ).

Female. Unknown.

Distribution. Only known from the type locality in Peru ( Fig. 82 View FIGURES 81−82 ).
