Etymology. The specific name is taken from the Tupi Indian language, it means “divided” and denotes the bifid tip of the embolus of the male palp. Unchangeable.

Diagnosis. Caayguara catuoca  sp. nov. is distinguished from the other species of the genus by the strongly bifid embolus in the male palp ( Fig. 66View FIGURES 66 – 70) and by the female epigynum with a median septum very narrow posteriorly and slightly divided anteriorly ( Fig. 68View FIGURES 66 – 70).

Description. Male ( IBSP 24820): Dorsal shield of prosoma pale orange, brown along fovea. Chelicerae and legs pale orange. Sternum pale yellow with orange margins. Labium and endites orange, distally cream colored. Opisthosoma gray, dorsally mottled with brown and white spots. Total length 10.8. Prosoma: 4.6 long, 4.1 wide. Opisthosoma: 5.6 long, 3.3 wide. Eye diameters: 0.32, 0.28, 0.22, 0.28; interdistances: 0.20, 0.04, 0.36, 0.36, 0.16, 0.12. Leg measurements: I: 30.2 (7.9, 2.8, 8.7, 8.2, 2.6); II: 34.5 (9.1, 3.0, 10.0, 9.6, 2.8); III: 22.3 (6.4, 2.3, 6.1, 5.8, 1.7); IV: 25.4 (7.2, 2.3, 6.7, 7.2, 2.0). Spination follows the generic pattern.

Palp ( Fig. 82View FIGURES 71 – 82): RTA simple with no lobes; dorsal projection absent ( Figs 66–67View FIGURES 66 – 70). Tegulum with small triangular projection ( Fig. 66View FIGURES 66 – 70; tp). Embolus with well developed pars pendula and bifid at tip ( Fig. 66View FIGURES 66 – 70).

Female ( IBSP 24828): Coloration pattern as in male. Total length 10.4. Prosoma: 4.0 long, 3.9 wide. Opisthosoma: 6.4 long, 4.2 wide. Eye diameters: 0.30, 0.32, 0.22, 0.30; interdistances: 0.20, 0.10, 0.40, 0.40, 0.20, 0.16. Leg measurements: I: 19.6 (5.4, 2.4, 5.3, 5.0, 1.5); II: 22.1 (6.3, 2.5, 6.1, 5.6, 1.6); III: 14.9 (4.5, 1.9, 3.8, 3.6, 1.1); IV: 17.0 (5.1, 1.8, 4.3, 4.4, 1.4). Spination follows the generic pattern. Epigynum: epigynal field slightly longer than wide; median septum almost twice longer than wide ( Fig. 68View FIGURES 66 – 70). Vulva: pp with 3–4 linearly arranged lobes; fd transversal slightly shorter than pp ( Figs 69–70View FIGURES 66 – 70).

Variation. Males (n = 10): total length 8.2–10.8; prosoma 3.7–4.6; femur I 6.2 –8.0. Females (n = 6): total length 10.4–12.1; prosoma 4.0– 5.3; femur I 5.2–5.9.

Distribution. Southeastern Atlantic Forest, only Serra do Mar in the state of São Paulo ( Fig. 87View FIGURE 87).
