Differential diagnosis Among the members of its species group, the female of S. satanas s. lat. can easily be recognized by having an entirely black scutellum and metanotum ( Figs 113–114 ). In S. pseudosatanas sp. nov. ( Fig. 109 ) and S. rufoclypeatus sp. nov. ( Fig. 110 ), these areas are completely ferruginous instead, and S. socotrensis sp. nov. has the metanotum and the posterior margin of the scutellum ferruginous ( Fig. 116 ). The subspecies S. satanas memnon subsp. nov. has the propodeal setae black instead of silvery ( Fig. 114 ). Male specimens are slightly harder to distinguish. They are characterized though their somewhat infuscate cellular wing area ( Fig. 115 ), whereas the other members of the group have it barely fuscous or completely hyaline. Furthermore, males of S. satanas possess narrow placoids on the proximal halves of flagellomeres IV–VI, a configuration similar to that of S. socotrensis sp. nov. and S. pseudosatanas sp. nov. However, these two species lack the more or less distinct folding just above the middle of the free clypeal margin, which is present in S. satanas and S. rufoclypeatus sp. nov. (compare Fig. 28 ).

Remarks The original description states that the type series consists of five females and three males collected in Boma and housed in the Royal Belgian Museum in Brussels . We were able to locate a matching number of specimens, the locality labels of which read “Boma” or “Boma Sundi”, that had been distributed between IRSN and MRAC. Some of them had already been labelled as paratypes by unknown revisers or collection staff, but since these designations were apparently never published, they are not valid. Also, there are a male and a female specimen from Boma bearing type labels by Kohl in the NHMW collection. Which of the aforementioned ten specimens actually constitute the type series cannot be determined with complete certainty, but we feel confident in designating a specimen from the IRSN as the lectotype .
