FIGURES 69−72. Curicaberis manifestus (O. Pickard-Cambridge) comb. nov. 69− 70 male, left palp (69 ventral, 70 retrolateral); 71− 72 female (71 epigyne, ventral view; 72 vulva, dorsal view). C = conductor; CD = copulatory duct; dRTA = dorsal branch of RTA; E = embolus; FD = fertilization duct; LL = lateral lobes; MS = median septum; mtp = median triangular protrusion; SP = spermathecae; tk = tegular hyaline keel; vRTA1 = projection 1 of ventral branch of RTA; vRTA2 = projection 2 of ventral branch of RTA. Scale lines: 1 mm.

Diagnosis. Males of C. manifestus comb. nov. are distinguished from those of the other species of the genus by the palp with conductor with strongly sclerotized base and small, pointed projection and by the presence of a longitudinal hyaline tegular keel (tk) close to the base of the conductor (Fig. 69). Females are distinguished from the other species of the genus by the epigyne with median septum short, rectangular, almost three times wider than long with pair of median, roughly triangular protrusions (Fig. 71: mtp) and by their vulva with L-shaped copulatory ducts (Fig. 72).

Description. Male (syntype): Prosoma pale brown, darker along fovea and thoracic striae. Chelicerae pale brown with darker brown longitudinal stripe. Legs and pedipalps pale brown. Sternum pale orange with pale brown margins. Labium and endites pale yellow, pale brown at base. Opisthosoma pale yellowish brown with indistinct dorsal darker brown pattern. Total length 8.1. Prosoma: 3.6 long, 3.7 wide. Opisthosoma: 3.9 long, 2.6 wide. Eyes: diameters: 0.34, 0.30, 0.22, 0.27; interdistances: 0.21, 0.07, 0.40, 0.35, 0.28, 0.23. Legs (2143): I: 22.3 (5.9, 2.2, 6.2, 6.2, 1.8); II: 24.2 (6.4, 2.3, 7.0, 6.7, 1.8); III: 15.8 (4.7, 1.7, 4.2, 3.8, 1.4); IV: 18.8 (5.4, 1.8, 5.0, 5.1, 1.5). Palp: dRTA short, large, with subdistal-ventral triangular projection. vRTA1 ovoid in retrolateral view with small, pointed projection at base. vRTA2 small and conical emerging from base of dRTA. Embolus arising from tegulum at 7 o’clock position (Figs 69−70).

Female (syntype): Coloration pattern as in male. Total length 9.3. Prosoma: 3.7 long, 3.9 wide. Opisthosoma: 5.4 long, 3.3 wide. Eyes: diameters: 0.30, 0.30, 0.24, 0.27; interdistances: 0.31, 0.13, 0.50, 0.45, 0.35, 0.30. Legs (2143): I: 18.8 (5.3, 2.1, 4.9, 5.0, 1.5); II: 20.9 (5.9, 2.4, 5.6, 5.5, 1.5); III: 13.5 (4.2, 1.6, 3.4, 3.1, 1.2); IV: 16.0 (5.0, 1.7, 3.9, 4.1, 1.3). Epigyne: epigynal field roughly trapezoid. Median septum with posterior margin not surpassing the epigastric furrow (Fig. 71). Vulva: spermathecae bean-shaped. Glandular projection not seen in dorsal view, (probably hidden behind copulatory ducts). Basal part of fertilization duct as wide as copulatory ducts, distal part antero-mediad (Fig. 72).

Variation. Males (n=3): total length 7.0−9.8; prosoma length 3.2−4.3; femur I length 5.9−7.2. Coloration of fresh specimens generally lighter than that of syntypes. Prosoma with dark brown stripes along lateral margins of cephalic region and thoracic striae. Legs mottled with small brown spots. Opisthosoma yellowish gray with dark brown lines along lateral margins of cardiac impression, fusing at the end and extending posteriorly. Laterally with pale brown longitudinal marks and ventrally with dark brown median longitudinal stripe.

Distribution. Known from the state of Chiapas , Mexico, from an undetermined locality in Guatemala and from the state of Cartago, Costa Rica (Map 3).
