Type material: Holotype: ♂, Chamela [19°31’N, 105°04’W], Jalisco , Mexico, 7 September 1981, M.L. Jimenez leg. ( CNAN 3349). Paratype: 1♀, Estación Biológica Chamela [19°29’N, 105°02’W], Chamela , Jalisco , Mexico, September 1988, W. Eberhard leg. ( MCZ 99589).

Etymology. The specific name is a patronym in honor of Mr. Antonio Urquiza, who donated the land that is now the Chamela Biological Station.

Diagnosis. Males of C. urquizai sp. nov. are distinguished from those of the other species of the genus by the palp with conductor large, heavily sclerotized with rugose retrolateral margin and conspicuous median striae (Fig. 95). The females are distinguished by the epigyne with median septum with pair of large, elongate copulatory openings, almost as long as median septum length (Fig. 97) and by the vulva, with basal part of fertilization ducts with grate-shaped margins (Fig. 98).

Description. Male: Prosoma pale brown, slightly darker at eye area, along lateral margins of cephalic region and thoracic striae. Fovea reddish-brown. Chelicerae brown, darker than prosoma. Legs and pedipalps pale brown ( Fig. 7 ). Labium orange, distally cream colored and brown at base. Endites orange, distally cream colored. Sternum orange with brown margins. Opisthosoma yellowish cream-colored, dorsally with two pairs of brown marks at margins of cardiac impression, smaller, longitudinal, pale brown marks laterally and five brown median chevronlike marks in posterior half ( Fig. 7 ), ventrally with wide, longitudinal brown stripe. Total length 15.5. Prosoma: 6.9 long, 6.7 wide. Opisthosoma: 8.0 long, 5.7 wide. Eyes: diameters: 0.50, 0.44, 0.34, 0.40; interdistances: 0.24, 0.08, 0.64, 0.64, 0.40, 0.26. Legs (2143): I: 41.8 (11.1, 3.5, 11.5, 12.0, 3.7); II: 45.3 (11.9, 3.9, 12.8, 12.8, 3.9); III: 30.3 (8.9, 3.2, 8.0, 7.7, 2.5); IV: 35.0 (10.6, 3.2, 9.0, 9.5, 2.7). Palp: dRTA long. vRTA1 small and triangular. vRTA2 bifid, with one pointed and one rounded projection. Subtegulum not visible in ventral view. Embolus slender, arising from tegulum at 8 o’clock position (Figs 95−96).

FIGURES 95−98. Curicaberis urquizai sp. nov. 95− 96 male, left palp (95 ventral, 96 retrolateral); 97− 98 female (97 epigyne, ventral view, 98 vulva, dorsal view). C = conductor; CD = copulatory duct; CO = copulatory opening; dRTA = dorsal branch of RTA; E = embolus; FD = fertilization duct; GP = glandular projection; LL = lateral lobes; MS = median septum; SP = spermathecae; vRTA1 = projection 1 of ventral branch of RTA; vRTA2 = projection 2 of ventral branch of RTA. Scale lines: 1 mm.

Female: Prosoma with thoracic region yellowish brown and cephalic region pale brown with darker brown marks along lateral margins and medially. Chilum reddish-brown. Chelicerae reddish-brown with conspicuous pale brown condyle. Legs and pedipalps as in male, slightly lighter ( Fig. 8 ). Sternum, labium and endites as in male. Opisthosoma as in male, except dorsally much darker, dark brown laterally ( Fig. 8 ). Total length 15.3. Prosoma: 7.0 long, 7.0 wide. Opisthosoma: 7.8 long, 6.0 wide. Eyes: diameters: 0.52, 0.50, 0.22, 0.26; interdistances: 0.32, 0.22, 0.86, 0.94, 0.38, 0.42. Legs: I: absent; II: 35.6 (10.2, 4.0, 9.4, 9.1, 2.9); III: 24.0 (7.4, 3.1, 6.0, 5.5, 2.0); IV: 26.5 (8.2, 3.0, 6.5, 6.7, 2.1). Epigyne: epigynal field semi-circled, two times wider than long. Median septum rectangular, two times wider than long, posterior margins not surpassing the epigastric furrow (Fig. 97). Vulva: copulatory ducts slightly longer than spermathecae length. Spermathecae oval, longer than wide. Distal part of fertilization ducts antero-mediad (Fig. 98).

Distribution. Known from the state of Jalisco , Mexico (Map 5).
