Parabomis martini Lessert, 1919: 116   , pl. 2, figs 6–8, 15 (Lectotype ³ and 1♀ paralectotype, here designated: TANZANIA: Kilimandjaro Region: Kibonoto (Kibognoto), 03°12’S, 37°07’E, MNHN—examined; 2♀ paralectotypes: KENYA: Mt Meru, Ngare na Nyuki [now Nanyuki], 03°05’S, 39°51’E, MGNH—examined); Millot 1942: 33, fig. 15A–B.

Parabomis anabensis Lawrence, 1928: 246   , pl. 22, fig. 29 (Holotype ♀: NAMIBIA: Kaoko Otavi, 18°18’S, 13°41’E, found on tree Grewia monticola, SAM   7035—examined); 1♀ paratype: NAMIBIA: Anabib , 18º10’S, 12º31’E, SAM 6690 View Materials —examined). syn nov GoogleMaps   .

Diagnosis. Males resemble those of P. wandae   sp. nov., with the RTA apex directed laterad in both species. They differ by the RTA in P. wandae   sp. nov. having a broad base and beak-like form ( Fig. 28 View FIGURES 26–30 ), compared to sharply pointed tip of P. martini   . The males also differ in the profile of the abdomen, which is round in P. martini   and humpshaped in P. wandae   sp. nov. In the females, the atrium is subtriangular ( Fig. 13 View FIGURES 10–14 ) in P. martini   and egg-shaped in P. wandae   sp. nov.

Remark. Parabomis anabensis Lawrence, 1928   from Namibia is known only from a female, which resembles P. martini   closely in all aspects and is here regarded as its junior synonym.

Biology/Habitat. Parabomis martini   has been collected from a variety of habitats in the Grassland and Savanna Biomes, ranging from grass, trees in thorny bushveld, and the undergrowth of coastal dune forest. Tree species that they have been collected from include Buddleia saligna   , Euclea crispa   , Dombeya   sp., Vitex rehmanni   and Pterocelastrus tricuspidatus ( Dippenaar-Schoeman et al., 2009)   . In Namibia, P. anabensis   was collected from the tree Grewia monticola   , and according to Lawrence (1928) the spider closely resembles its flowers.
