Etymology. The specific name is a noun in apposition taken from the type locality.

Diagnosis. Males of Guadana neblina sp. nov. are easily distinguished from those of the remaining species of the genus by the palp with hook-shaped dorsal branch of the RTA, by the bifid embolus with short and thick tips and by the very slender conductor ( Figs 20–21 ).

Chelicerae pale yellow with lateral black spot at base. Legs and pedipalps pale yellow with gray spots at the base of spines. Sternum cream colored with pale yellow margins. Labium and endites pale yellow, distally lighter. Opisthosoma pale yellow. Dorsally covered with bright orange hairs and patches of black hairs laterally, around muscular impressions and close to anal tubercle ( Fig. 5 ). Ventrally mottled with white spots. Total length 6.4. Prosoma: 2.9 long, 3.0 wide. Opisthosoma: 3.5 long, 2.9 wide. Eye diameters: 0.20, 0.24, 0.16, 0.26; interdistances: 0.12, 0.02, 0.26, 0.26, 0.24, 0.26. Legs: I: 25.0 (6.4, 1.7, 7.4, 7.1, 2.4); II: 27.8 (7.0, 1.9, 8.3, 8.1. 2.5); III: 17.5 (4.7, 1.5, 4.7, 4.9, 1.7); IV: 20.2 (5.2, 1.4, 5.3, 6.1, 2.2).
