Etymology. The species name is Latin for “western”, referring to its distribution in West Africa.

Diagnosis. Females of the species can be recognised by the narrow copulatory ducts directed at 45° towards ST II from the copulatory openings, with the ST II strongly expanded posterolaterally and nearly touching the copulatory ducts ( Fig. 57 View FIGURES 56 – 59 ). Males can be distinguished by the narrow base of the embolus and the distal section that is approximately three times longer than the basal section ( Fig. 46 View FIGURES 45 – 51 ).

Distribution. Known only from the Ivory Coast ( Fig. 68 View FIGURE 68 ).

Natural history. In contrast to most of the Echinax material from Africa, which was mainly collected in forest habitats, specimens of E. hesperis were collected exclusively in tropical savanna. Other records of the genus from this country ( E. longespina ) were collected in forests only.
