Beschreibung:
<jats:p>Recent collections from the south-eastern Lowveld of Zimbabwe yielded an undescribed species of the freshwater branchiopod genus <jats:italic>Streptocephalus</jats:italic>. The species was formerly published as <jats:italic>Streptocephalus</jats:italic> cf. <jats:italic>bidentatus</jats:italic> by Brendonck & Riddoch (1997), indicating that more research was needed to prove its valid species status, distinct from <jats:italic>S. bidentatus</jats:italic> sensu stricto. The new species can be distinguished from <jats:italic>S. bidentatus</jats:italic> sensu stricto, mainly by its cercopods. The cercopods of <jats:italic>S. bidentatus</jats:italic> sensu stricto have spines in the distal third region of the furcal rami, while those of <jats:italic>S. sangoensis</jats:italic> n. sp. are setiferous up to the tips. All other morphological features are the same. The occurrence of the two species in syntopy further validates that they are different species. As with <jats:italic>S. bidentatus</jats:italic> sensu stricto, the new species <jats:italic>S. sangoensis</jats:italic> n. sp. was collected from ephemeral habitats. This region is a hotspot of large branchiopod diversity with a total of 16 known species occurring there.</jats:p>
