Etymology. The specific name refers to the type locality, noun in apposition.

Diagnosis. Eleleis etosha   sp. nov. is distinguished from other species of the genus by the presence of spines on the legs ( Fig. 12C View FIGURE 12 ). Males resemble those of E. himba   sp. nov. by RTA mostly straight with a ventral tip bent distally in retrolateral view, but differ by tegular excavation located away from the conductor (very close to the conductor in E. himba   sp. nov.) ( Fig. 21C View FIGURE 21 ). Females resemble those of E. haddadi   sp. nov. and E. solitaria   sp. nov. by the posterior median excavation smaller than the median atrium. They differ from the latter by the bullet shape of the atrium, more than two times longer than wide (subrectangular, more than two times wider than long in E. haddadi   sp. nov. and large and round, larger than the posterior median excavation in E. solitaria   sp. nov.) ( Fig. 21D View FIGURE 21 ).

Leg measurements: I: 2.93 (0.90, 0.50, 0.60, 0.48, 0.45); II: 2.46 (0.75, 0.39, 0.49, 0.44, 0.40); III: 2.18 (0.63, 0.35, 0.38, 0.44, 0.39); IV: 3.13 (0.89, 0.48, 0.63, 0.61, 0.53). Leg spination: I—femur d1-1-0. II—d1-1-0. III—femur d1-1-0. IV—femur d1- 1-1; tibia v0-1r-1r. Epigyne: atrium with anterior margin sclerotized; posterior median excavation rounded, as long as wide ( Fig. 21D View FIGURE 21 ). Vulva: proximal part of copulatory duct running anteriorly, parallel to each other; fertilization ducts arising medially from primary spermathecae ( Fig. 21E View FIGURE 21 ).
