Table 3
(continued on next page). Table for quick-identification of males based on placoid configuration. 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.

Description
Female
SIZE.
34.1–42.5 mm
.
COLOR. Black or dark brown except for the following, which are ferruginous: basal half of mandible, clypeus, scape, pedicel, flagellomeres I–VI, neck, collar, tegula, scutum except anterior margin and medial longitudinal stripe, scutellum, propodeum, petiole dorsally, metasomal segment I, metasomal segment II except posterior margin and legs from coxa onward excluding claw. Cellular wing area yellowish, apex including marginal cell and submarginal cell III of forewing fuscous.
VESTITURE. Appressed and erect setae on clypeus, paraocular area, collar, scutum and propodeal enclosure rich or pale golden. Erect propodeal setae oriented perpendicularly. Lower center of clypeus with glabrous spot. Scutellum finely and densely pubescent.
STRUCTURE. Free clypeal margin simple, stepped medially. Clypeus without indentation and carina. Scutellum flat. Metanotum not raised, not bituberculate. 2
nd
recurrent vein joins slightly proximal from interstitium between submarginal cells II and III. Propodeal enclosure with 15–20 distinct ridges. Foretarsomere I 2.5–2.6× length of antepenultimate spine. Petiole length 2.1–2.2× its medial width.
Male
SIZE. 26.7–32.0 mm.

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.
