Figs 11 –12View FIGURES 9 – 12, 49–52View FIGURES 49 – 52, 59View FIGURE 59

Type material. Holotype: ♂ from Palenque  River, 47 km S Santo Domingo (00° 15 ’ 16 ”S, 78 ° 49 ’09”W), Pichincha, Ecuador, 5 May– 25 August 1985, S. & J. Peck leg. (AMNH). Paratypes: 2 ♂, 1 ♀ (AMNH); 1 ♂, 1 ♀ (IBSP 163253), all with the same data as holotype.

Etymology. The specific name is a noun in apposition and refers to the type locality.

Diagnosis. Males of U. palenque  sp. nov. resemble those of U. barroana (Chamberlin)  comb. nov. and U. ope  sp. nov. in the very long retrolateral groove on the cymbium of the male palp, extending throughout most of the cymbium length ( Figs 34View FIGURES 33 – 36, 46View FIGURES 45 – 48, 50View FIGURES 49 – 52). They are distinguished from these species by the very long cymbium, more than 4 times the length of tibia, and by the conductor very widened distally ( Fig. 49View FIGURES 49 – 52). The females resemble those of U. barroana (Chamberlin)  comb. nov., U. ope  sp. nov. and U. quyguaba  sp. nov. in the subrectangular shape of the median septum ( Figs 35View FIGURES 33 – 36, 46View FIGURES 45 – 48, 51View FIGURES 49 – 52, 55View FIGURES 53 – 56) and in the very long and strongly convoluted Cp ( Figs. 36View FIGURES 33 – 36, 47View FIGURES 45 – 48, 52View FIGURES 49 – 52, 56View FIGURES 53 – 56). They are distinguished from the latter species by the Lp short and tapering towards the Cp ( Fig. 52View FIGURES 49 – 52).

Description. Male (AMNH, holotype): Prosoma brown with brown margins, brown fovea and brown Ushaped mark extending from eye area to posterior margin of prosoma. Eye area slightly darker than prosoma and eye borders black. Chelicerae brown with median longitudinal brown stripe. Legs and pedipalps pale brown, lighter than prosoma, with pale brown incomplete bands ( Fig. 11View FIGURES 9 – 12). Labium and endites pale orange, distally lighter. Sternum orange with darker sclerotized margins. Opisthosoma brownish gray with very faint dorsal pattern of few scattered marks on anterior half and few irregular marks posteriorly ( Fig. 11View FIGURES 9 – 12). Total length 6.2. Prosoma 2.7 long, 2.4 wide. Opisthosoma 3.0 long, 1.7 wide. Eyes: diameters: 0.2, 0.16, 0.14, 0.16; interdistances: 0.1, 0.04, 0.2, 0.16, 0.1, 0.06. Legs: I: 11.4 (3.2, 1.3, 3.3, 2.8, 0.8); II: 11.4 (3.3, 1.2, 3.3, 2.9, 0.7); III: 8.8 (2.6, 1.1, 2.1, 2.3, 0.7); IV: 10.5 (3.0, 1.0, 2.6, 3.0, 0.9). Spination: tibiae I–II: v 8 pairs. Palp: tibia with one prolateral spine; dRTA only slightly larger than vRTA; vRTA subtriangular with distally twisted tip; VTA absent; cymbium long with retrolateral groove, flanked by strong setae and extending throughout its entire length; tegulum flanked prolaterally by hyaline lamina, protruding at the base of embolus and becoming slightly membranous at the base of conductor; median apophysis cup-shaped with bilobed margin; embolus long and slender, arising between 4 and 4: 30 o’clock ( Figs 49–50View FIGURES 49 – 52).

Female (AMNH, paratype): Coloration pattern as in male, slightly more orange ( Fig. 12View FIGURES 9 – 12). Total length 6.0. Prosoma 2.5 long, 2.0 wide. Opisthosoma 3.4 long, 2.0 wide. Eyes: diameters: 0.16, 0.14, 0.1, 0.1; interdistances: 0.12, 0.06, 0.18, 0.16, 0.1, 0.06. Legs: measurements: I: 9.0 (2.5, 1.2, 2.5, 2.2, 0.6); II: 8.8 (2.7, 1.1, 2.3, 2.1, 0.6); III: 7.0 (2.1, 1.0, 1.6, 1.7, 0.6); IV: 8.8 (2.5, 0.9, 2.0, 2.5, 0.9). Spination: femora I–II: p 0-1 - 1; r0- 0-1; femur III: r 1 - 1 -0; tibiae I–II: v 7 pairs. Epigyne: epigynal field slightly longer than wide; lateral lobes with posterior triangular projections reaching the posterior margin of the median septum; median septum subrectangular, two times longer than wide ( Fig. 51View FIGURES 49 – 52). Vulva: gp inconspicuous; fertilization ducts short, pointing away from each other ( Fig. 52View FIGURES 49 – 52).

Variation. Males (n = 5): total length 5.3–6.2; prosoma length 2.4 –3.0; femur I length 2.8–3.2. Females (n = 3): total length 6.0– 6.2; prosoma length 2.4–2.5; femur I length 2.4–2.6.
