Each flagellomere is represented by three symbols, each of which describes the form of the placoid in the respective approximate third of the segment. If all subspecies have identical placoid configurations, they are combined as sensu lato (‘s. lat.’). Notable, but unnamed variations are listed below the respective taxon as ‘var.’. The presence of an arrow indicates that different specimens can vary between the states shown, with intermediate forms occurring. The names of new species are highlighted in bold. Legend: ‘-’ = placoid absent; ‘o’ = placoid narrow; ‘O’ = placoid broad

Differential diagnosis Among the African Sphex , this species is very easy to recognize due to its short erect setae on the propodeal enclosure, the two swellings on each propodeal side ( Fig. 40 ), and the conspicuous coloration ( Fig. 39 ) and large body size. Etymology Menkeella is named in honor of Dr Arnold S. Menke. Material examined AFRICA 1 ♂ ; “ Congo ”; MNHN .

Mesosomal side (anterior = left). Distribution Western and eastern Africa. Remarks This species differs from the other Sphex s. str. through its absence of a complete spiracular groove. Instead, it possesses a sulcus that connects the lower metapleural pit with the anteroventral pit ( Fig. 40 ). Similar to members of the argentatus group ( Fig. 9 ), S. paulinierii also has a swelling anteroventrally of the spiracle, although it has an additional swelling posteriorly to it, laterally on the propodeal enclosure. This posterior swelling is unique, and S. paulinierii lacks the distinctly impressed, bituberculate metanotum that is characteristic for the argentatus group. Furthermore, its very short erect propodeal setae are unusual for Sphex , and no longitudinal carina is present on the female labrum. For these reasons, with particular emphasis on a complete spiracular groove being an extremely important defining character for the subgenus Sphex ( Bohart & Menke 1976 ) and the lack of distinctive characteristics for species group assignment, we have decided to place S. paulinierii in a separate subgenus.
