Diagnosis. Males of C. annulatus comb. nov. are distinguished from those of the other species of the genus by the palp with oblique depression at the base of vRTA, vRTA1 pointed and strongly bent prolaterally and vRTA2 with a small pointed projection at tip (Fig. 17). Females resemble those of C bibranchiatus comb. nov., C. peninsulanus comb. nov. and C. tortugero sp. nov. by the epigyne with median septum with lateral protrusions (Figs 19, 93: lp, Rheims 2010c: 531, figs 3, 7). They are distinguished by the lateral protrusions extending a little over one-third of the median septum width on each side and reaching almost half the median septum length, forming an oval atrium two times wider than long (Fig. 19). They are further distinguished from other species of the genus by the vulva, with kidney-shaped spermathecae (Fig. 20).

Note. The female herein described is considered conspecific to the male based on the proximity of the collection localities and similarities of the general habitus.

Description. Male (holotype): Badly preserved specimen. Prosoma, chelicerae, legs, pedipalps, labium, endites and sternum brown, dried out. Opisthosoma brownish-gray. Total length 7.4. Prosoma: 3.6 long, 3.7 wide. Opisthosoma: 3.8 long, 2.0 wide. Eyes: diameters: 0.28, 0.26, 0.22, 0.24; interdistances: 0.18, 0.06, 0.34, 0.28, 0.14, 0.14.

Subtegulum visible at 9:30 o’clock position. Embolus long, sinuous, arising from tegulum at 9 o’clock position. Conductor slightly widened at tip (Figs 17−18).

Female (AMNH): Prosoma orange with black marks scattered on cephalic region, mainly at the base of setae. Fovea brown. Eye borders black. Chelicerae and pedipalps orange. Legs orange, ventrally mottled with brown spots. Tibiae and metatarsi with brown transversal bands. Sternum yellow with pale orange margins. Endites orange, distally pale yellow. Labium brown, distally pale yellow. Opisthosoma cream-colored. Dorsally with faint pale brown pattern of scattered marks laterally and on anterior half and chevron-like marks on posterior half. Total length 13.3. Prosoma: 4.3 long, 4.4 wide. Opisthosoma: 8.4 long, 6.2 wide. Eyes: diameters: 0.32, 0.30, 0.24, 0.28; interdistances: 0.24, 0.10, 0.44, 0.42, 0.24, 0.22. Legs (2143): I: 20.0 (5.9, 1.8, 5.5, 5.0, 1.8); II: 26.6 (7.6, 2.4, 7.3, 7.0, 2.3); III: 15.7 (4.8, 1.9, 3.9, 3.8, 1.3); IV: 19.3 (5.8, 2.0, 4.8, 5.2, 1.5). Epigyne: epigynal field rounded, slightly longer than wide. Posterior margin of median septum not surpassing epigastric furrow (Fig. 19). Vulva: copulatory ducts as long as spermathecae. Basal part of fertilization ducts slender, relatively straight, distal part laterad (Fig. 20).

Distribution. Only known from the region of Acapulco, in the state of Guerrero, Mexico (Map 1).
