Figs 99−100

Type material: Holotype: ♀, Yerba Santa, Santo Domingo Zanatepec [16°28’N, 94°21’W], Oaxaca, Mexico, 7 January 1948, T. MacDougall leg. ( AMNH).

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

Diagnosis. Females of C. yerba sp. nov. are distinguished from those of the remaining species of the genus by the epigyne with median septum triangular (Fig. 99). Males are unknown.

Description. Female: Prosoma brown, slightly darker at eye area, with reticulated markings close to margins of thoracic region and along lateral margins of cephalic region. Fovea dark brown. Eye borders black. Chelicerae dark brown. Legs and pedipalps brown. Sternum orange brown with brown margins. Labium and endites brown, distally pale orange. Opisthosoma pale yellowish brown. Dorsally with dark brown marks laterally and along cardiac mark and with brown chevron like marks on posterior half. Ventrally with thick, brown, longitudinal stripe. Total length 11.8. Prosoma: 5.0 long, 5.3 wide. Opisthosoma: 6.6 long, 4.7 wide. Eyes: diameters: 0.39, 0.37, 0.27, 0.32; interdistances: 0.28, 0.14, 0.53, 0.54, 0.35, 0.30. Legs (2143): I: 25.3 (7.2, 2.7, 6.5, 6.9, 2.0); II: 26.5 (7.9, 2.7, 7.0, 6.9, 2.0); III: 17.9 (5.9, 2.1, 4.4, 4.1, 1.4); IV: 20.5 (6.2, 2.3, 5.3, 5.2, 1.5). Epigyne: epigynal field triangular, longer than wide. Posterior margin of median septum not surpassing the epigastric furrow (Fig. 99). Vulva: copulatory ducts as long as largest spermathecae length. Spermathecae asymmetrical, one smaller, rounded, the other oval, narrow, longer than wide. Both with remnants of internal duct system seen by transparency. Basal part of fertilization ducts wide, almost as wide as copulatory ducts with irregular margins, distal part anteriad (Fig. 100).

Male: Unknown.

Distribution. Only know from the type locality in the state of Oaxaca, Mexico (Map 5).
