Differential diagnosisMales of this subspecies are most easily identifiable through the structure of their genitalia. Like S. schoutedeni schoutedeni, they have the fused penis valvae dorsally open, laterally not widened and with a notch (Figs 23–24). In the similar S. stadelmanni stadelmanni (Figs 21–22), the valvae are laterally widened, but lack a notch, and the valvicipites are curved posteroventrally and not perpendicularlyoriented as in S. schoutedeni s. lat. The males of the other species and subspecies of the bohemanni group all differ in having sternum VII or VIII modified in a conspicuous way (Figs 19–20, 25), whereas S. schoutedeni malawicus subsp. nov. has sternum VII without a notch and sternum VIII convex and entire. Finally, the nominotypical S. schoutedeni schoutedeni is distinguishable through having partially silvery propodeal setae (Fig. 94), while S. s. malawicus subsp. nov. has them black, with the exception of some erect golden setae at the posterior propodeal margin.
Females can be recognized based on the color of their clypeus and its vestiture. They, like all members of the bohemanni group, have the appressed setae black in the clypeal center, but the presence of golden appressed lateroclypeal and paraocular setae combined with a slightly ferruginous free clypeal margin is unique (Fig. 18).
EtymologyThis subspecies is named after the country of Malawi, where most of the material was collected.
