Type material: Holotype: ♂, Estación Biológica de Chamela [19°29’N, 105°02’W], Chamela , Jalisco , Mexico, September 1988, W. Eberhard leg. ( MCZ 99585). Paratypes: 1♀, same data as holotype ( MCZ 99585); 2♀, same locality and collector as holotype, September 1990 ( MCZ 99587); 1♀, same data as holotype ( MCZ 99586).

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

Diagnosis. Males of C. jalisco sp. nov. are distinguished from those of the other species of the genus by the palp with vRTA1 anvil-shaped (Fig. 61), vRTA2 T-shaped in retrolateral view and by the presence of an additional small triangular projection at the base of dRTA (Fig. 62: EP). Females are distinguished by the reduced median septum, almost completely covered by the lateral lobes (Fig. 63).

Description. Male (holotype): Prosoma pale orange, darker along fovea and thoracic striae. Chelicerae, legs and pedipalps orange ( Fig. 3 ). Labium and endites pale orange, distally pale yellow. Sternum pale yellow with pale brown margins. Opisthosoma dorsally grayish brown with darker brown cardiac impression ( Fig. 3 ). Ventrally pale yellow with longitudinal, median brown stripe. Total length 11.7. Prosoma: 5.4 long, 5.2 wide. Opisthosoma: 6.0 long, 4.0 wide. Eyes: diameters: 0.38, 0.34, 0.26, 0.30; interdistances: 0.24, 0.10, 0.40, 0.44, 0.24, 0.20. Legs (2143): I: 32.3 (8.6, 3.1, 8.7, 9.1, 2.8); II: 35.5 (9.5, 3.2, 9.9, 10.0, 2.9); III: 23.4 (6.9, 2.5, 6.0, 6.0, 2.0); IV: 28.2 (8.2, 2.6, 7.3, 8.0, 2.1). Palp: dRTA long. Subtegulum visible at 10 o’clock position. Embolus short, with large triangular base, arising medially from tegulum. Conductor distally widened (Figs 61−62)

Female (MCZ 99586): Coloration pattern as in male. Prosoma, chelicerae, legs and pedipalps darker. Opisthosoma brownish yellow, with pale brown cardiac impression and irregular dark brown longitudinal stripe, extending posteriorly from cardiac impression ( Fig. 4 ). Total length 13.7. Prosoma: 5.9 long, 6.0 wide. Opisthosoma: 7.4 long, 5.5 wide. Eyes: diameters: 0.40, 0.36, 0.26, 0.36; interdistances: 0.30, 0.16, 0.64, 0.56, 0.34, 0.28. Legs (2143): I: 26.4 (7.4, 3.1, 6.7, 7.0, 2.2); II: 28.9 (8.0, 3.2, 7.7, 7.6, 2.4); III: 19.4 (6.0, 2.5, 4.7, 4.5, 1.7); IV: 22.3 (6.9, 2.5, 5.5, 5.6, 1.8). Epigyne: epigynal field, roughly squared, as long as wide (Fig. 63). Vulva: copulatory ducts almost as long as spermathecae. Spermathecae large, oval with remnants of internal duct system seen by transparency. Basal part of fertilization ducts half the width of copulatory ducts, distal part anteriad (Fig. 64).

Variation. Females (n = 4): total length 11.8−14.3; prosoma length 5.0−6.1; femur I length 6.5−7.0.

Distribution. Known only from the type locality in the state of Jalisco , Mexico (Map 3).
