Parabomis elsae sp. nov.

Figures 4–7

Etymology. Named after Elsa van Niekerk (Pretoria South Africa), the graphic artist at Agricultural Research Council (ARC)—Plant Health and Protection, in recognition of her support for spider research at the ARC.

Diagnosis. Males and females of this species are recognized by their mottled bodies and copulatory organs (Figs 4, 5). Parabomis elsae sp. nov. females resemble those of P. megae sp. nov. in the shape of the epigyne, but the colour differs by being strongly mottled in P. elsae sp. nov. In males of both species the RTA apex is directed dorsad, but in P. elsae sp. nov. the RTA apex is claw-like (Fig. 6).
