Figs 87−90, Map 4

Type material: Holotype: ♂, San Pedrito Chicozapote, 4 km SSE Cuicatlan (17°46’N, 96°56’W), Oaxaca, Mexico, 16 October 1998, F. Alvarez, J.L. Castelo & C. Durán leg. ( CNAN 3352). Paratypes: ♀, Oaxaca de Juarez [17°04’N, 96°43’W], Oaxaca, Mexico, 15 June–15 August 1970, M.R. Bogert leg. ( AMNH); 1♀, Dominguillo [17°47’N, 96°57’W], Cuicatlan, Oaxaca, Mexico, 13 April 1998, F. Alvarez, J. Castelo & C. Duran leg. ( CNAN 3368).

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

Diagnosis. Males of C. sanpedrito sp. nov. resemble those of C. zapotec sp. nov. by the vRTA2 bifid with one projection longer than the other (Figs 88, 102). They are distinguished by the vRTA2 with longer branch almost two times longer than smaller distally widened branch, embolus long and gently curved retrolaterally and vRTA1 small, roughly squared (Figs 87−88). Females resemble those of C. chamela sp. nov. C. minax comb. nov. and C. abnormis comb. nov. by the epigyne with very large, rounded copulatory openings (Figs 29, 75, 89, Rheims 2010c: 534, fig. 11). They are distinguished from these species by the copulatory openings slightly further away from the margins of the lateral lobes (partly covered by them in the other species) (Fig. 89). They are further distinguished from the remaining species of the genus by the copulatory ducts slender and fishhook-shaped (Fig. 90).

Description. Male: Prosoma pale orange, slightly darker at eye area, brown along fovea, with brown marks scattered over cephalic region. Chelicerae and pedipalps pale orange. Legs pale orange mottled with pale gray spots. Labium orange, distally cream colored. Endites pale orange, distally cream colored. Sternum pale orange with slightly darker margins. Opisthosoma pale brown; dorsally with brown cardiac impression and brown markings laterally; ventrally mottled with brown spots. Total length 8.9. Prosoma: 4.2 long, 4.2 wide. Opisthosoma: 4.5 long, 3.2 wide. Eyes: diameters: 0.30, 0.26, 0.20, 0.24; interdistances: 0.16, 0.06, 0.38, 0.36, 0.28, 0.24. Legs (2143): I: 24.7 (6.8, 2.5, 6.6, 6.8, 2.0); II: 26.8 (7.4, 2.6, 7.4, 7.3, 2.1); III: 18.2 (5.5, 2.0, 4.7, 4.5, 1.5); IV: 21.8 (6.5, 1.8, 5.8, 6.0, 1.7). Palp: Subtegulum visible at 9:30 o’clock position. Embolus arising medially from tegulum. Conductor distally widened (Figs 87−88).

Female (CNAN 3368): Coloration pattern as in male. Total length 9.0. Prosoma: 4.0 long, 4.2 wide. Opisthosoma: 4.6 long, 3.2 wide. Eyes: diameters: 0.30, 0.26, 0.22, 0.22; interdistances: 0.26, 0.14, 0.48, 0.50, 0.38, 0.32. Legs (2143): I: 18.8 (5.3, 2.4, 4.7, 5.0, 1.4); II: 20.7 (6.0, 2.5, 5.3, 5.4, 1.5); III: 14.4 (4.5, 2.0, 3.5, 3.3, 1.1); IV: 16.9 (5.2, 2.0, 4.2, 4.4, 1.1). Epigyne: epigynal field wider than long. Posterior margin of median septum not surpassing the epigastric furrow (Fig. 89). Vulva: copulatory ducts slender, as wide as fertilization ducts and one and a half times the spermathecae length. Spermathecae small, rounded. Basal part of fertilization duct narrow, as wide as copulatory duct, distal part antero-mediad (Fig. 90).

Variation. Females (n = 2): total length 9.0−11.3; prosoma length 4.0−5.0; femur I length 5.3−6.1. Distribution. Known from southern Mexico, state of Oaxaca (Map 4).
