Type material: Holotype: ♀, “Campamento Tortugero ”, 4km SW Pueblo Barra de La Cruz (15°49’N, 95°57’W), Oaxaca, Mexico, 18 September 2000, E. Gonzales, O. Delgado, J. Castelo, E. lira & C. Durán leg. ( CNAN 3371). Paratypes: 1♀, Mexico [undetermined locality] ( AMNH).

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

Diagnosis. Females of C. torugero sp. nov. resemble those of C. bibranchiatus comb. nov. and C. annulatus comb. nov. by the epigyne with median septum with lateral protrusions (Figs 19, 93, Rheims 2010c: 531, fig. 3). They are distinguished by the lateral protrusions almost touching each other medially, forming an anterior oval atrium more than three times wider than long ( Fig. 93 ). They are further distinguished from the other species of the genus by the vulva with basal part of fertilization ducts heavily coiled ( Fig. 94 ). Males are unknown.

Description. Female (holotype): Prosoma pale yellow, slightly darker along thoracic striae. Fovea orange. Eye borders black. Chelicerae, legs and pedipalps pale yellow. Legs metatarsi and tarsi slightly darker than rest of leg. Sternum pale yellow. Labium and endites pale orange, distally pale yellow. Opisthosoma yellow, cream colored along cardiac mark. Total length 9.2. Prosoma: 4.1 long, 4.2 wide. Opisthosoma: 4.7 long, 3.5 wide. Eyes: diameters: 0.32, 0.30, 0.20, 0.24; interdistances: 0.20, 0.10, 0.42, 0.48, 0.26, 0.22. Legs (2143): I: 20.3 (5.7, 2.4, 5.2, 5.4, 1.6); II: 21.2 (6.1, 2.4, 5.5, 5.6, 1.6); III: 13.6 (4.3, 1.4, 3.4, 3.4, 1.1); IV: 17.1 (5.2, 2.0, 4.2, 4.5, 1.2). Epigyne: epigynal field semi-circled, wider than long. Posterior margin of median septum not surpassing the epigastric furrow ( Fig. 93 ). Vulva: copulatory ducts slender at copulatory openings curved and widening towards spermathecae. Spermathecae small, oval, wider than long. Distal part of fertilization ducts antero-laterad ( Fig. 94 ).

Male: Unknown.

Variation. Females (n = 2): total length 9.2−10.5; prosoma length 3.9−4.1; femur I length 5.0−5.7. Distribution. Only known from the type locality in the state of Oaxaca, Mexico (Map 5).
