Stenaelurillus guttatus (Wesołowska & Cumming, 2002) comb. nov.

Figs 8–9, 16–17, 165–183, 511

Mashonarus guttatus Wesołowska & Cumming, 2002: 167, figs 1–19 (D♂ ♀); ♂ holotype in MRAC, examined.

Diagnosis

By the conformation of the copulatory organs (the well-marked proximal projection of the functional tegulum, the stiletto-shaped embolus and the developed cymbial lateral projection, etc.), S. guttatus comb. nov. is most similar to S. brandbergensis comb. nov. and S. pseudoguttatus sp. nov. (cf. Figs 90– 94, 99–100, and 416–420). The males of S. guttatus comb. nov. differ in having a pointed distal projection (wide and obtuse in S. brandbergensis comb. nov., absent in S. pseudoguttatus sp. nov.) and the shortest RTA (as compared with the two related species). The females differ in having comparatively long insemination ducts (very short in S. brandbergensis comb. nov., not yet known in S. pseudoguttatus sp. nov., cf. Figs 172 and 100).

Remarks

The original type series of Mashonarus guttatus turned out to include two species. The male paratype from Namibia (MRAC 152.151) actually belongs to a separate and new species that is described below as S. pseudoguttatus sp. nov.
