Figs 11–12, 49–52, 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 34, 46, 50). 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. 49). 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 35, 46, 51, 55) and in the very long and strongly convoluted Cp (Figs. 36, 47, 52, 56). They are distinguished from the latter species by the Lp short and tapering towards the Cp (Fig. 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. 11). 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. 11). 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 49–50).
Female (AMNH, paratype): Coloration pattern as in male, slightly more orange (Fig. 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: p0-1-1; r0-0-1; femur III: r1- 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. 51). Vulva: gp inconspicuous; fertilization ducts short, pointing away from each other (Fig. 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.
Distribution. Ecuador (Fig. 59).
