Differential diagnosis

Females of S. haemorrhoidalis (Fig. 69) and S. victoria sp. nov. (Fig. 73) cannot always be distinguished satisfactorily. Especially in specimens from central Africa, where their populations overlap, it is often difficult to decide what color the luster of the appressed paraocular and clypeal setae is, which is one of the only useful diagnostics. The coloration of the legs can also be somewhat helpful, but is variable as well. Thus, the character states mentioned represent the more distinct manifestations that occur mostly in eastern and western Africa for S. victoria sp. nov. and S. haemorrhoidalis, respectively.

In the female of S. haemorrhoidalis, the appressed setae laterally on the clypeus and on the paraocular area have a ferruginous luster (Fig. 34). In contrast, it has a silvery luster in S. victoria sp. nov. (Fig. 35). Furthermore, S. victoria sp. nov. has at least the apical half of the hindfemora ferruginous, whereas in S. haemorrhoidalis the hindfemora are predominantly black. Females of S. mweruensis are distinguishable through having the erect setae at the posterior propodeal margin silvery (Fig. 64), while those of S. umtalicus have the clypeus (Fig. 33) and most of the body black (Fig. 72), and both sexes of S. caeruleanus can be recognized though their very distinctly green wing iridescence (Fig. 63).

Males (Fig. 74) are identifiable through the combination of having uniformly black setae on the thoracical dorsum, the mandibular base brightly ferruginous and the hindtibia at least partially ferruginous. Those of S. haemorrhoidalis (Fig. 70) and S. mweruensis (Fig. 65) have a substantial number of erect mesanotal setae silvery, and S. umtalicus has the legs uniformly black.

Etymology

This species was named after Lake Victoria, as most of the material was collected in its vicinity.
