Diagnosis. Decaphora pestai resembles D. kohunlich spec. nov. by mRTA with many distal spines and dRTA very long and slender in the male palps (Figs 23−24 vs. 30–31) and by lateral lobes of the female epigyne with posterior triangular projections (Figs 26 vs. 34). The males are distinguished by the slightly oval TBC and conical TBE (Fig. 30). The females are distinguished by the epigyne with touching part of LL 1.5 times longer than the median septum length (Fig. 34).
Redescription. Male (USNM): Prosoma orange with brown fovea and very faint darker orange thoracic striae. Chelicerae, legs and pedipalps orange. Sternum pale yellow with pale orange margins. Labium and endites pale yellow. Opisthosoma cream colored, mottled with brown spots (Fig. 5). Total length 8.9. Prosoma: 4.4 long, 3.9 wide. Opisthosoma: 4.3 long, 2.6 wide. Eyes: diameters: 0.26, 0.22, 0.16, 0.20; interdistances: 0.20, 0.06, 0.44, 0.36, 0.14, 0.18. Legs (2-1/4-3): I: 16.9 (4.7, 2.3, 4.5, 4.4, 1.0); II: 17.1 (5.0, 2.5, 4.5, 4.2, 0.9); III: 13.6 (4.1, 2.0, 3.1, 3.6, 0.8); IV: 16.9 (4.9, 1.8, 4.0, 5.0, 1.2). Leg and palp spination follow the generic pattern. Palp: tibia short, with no spines (Fig. 29); PTP long and cylindrical (Fig. 30).
Female (CAS): Coloration pattern as in male, except opisthosoma with brown pattern of 8–9 median, inverted V-shaped marks and lateral spots (Fig. 6). Total length 9.6. Prosoma: 4.0 long, 3.6 wide. Opisthosoma: 5.5 long, 3.5 wide. Eyes: diameters: 0.28, 0.22, 0.16, 0.20; interdistances: 0.22, 0.10, 0.42, 0.38, 0.16, 0.14. Legs (2-1-4-3): I: 12.1 (3.4, 2.0, 3.3, 2.7, 0.7); II: 12.3 (3.7, 2.0, 3.2, 2.7, 0.7); III: 10.0 (3.2, 1.6, 2.2, 2.3, 0.7); IV: 12.0 (3.6, 1.5, 2.7, 3.2, 1.0). Leg and palp spination follow the generic pattern. Epigyne: median septum oval, wider than long (Fig. 34). Vulva: fertilization ducts pointing away from each other (Figs. 35−36)
Variation. Males (n = 2): total length 8.3–8.9; prosoma length 4.2–4.4; femur I 4.2–4.7.
Distribution. Known from Central America from Belize to Costa Rica (Fig. 45).
