Sphex decipiens Kohl, 1895: 65 , ♀, ♂ (syntypes: ♀, ♂, South Africa, former Cape Province, NHMW, examined).

Differential diagnosis

This species is very distinct from the other members of the g aullei group, as both sexes have the clypeus black except near the free clypeal margin ( Figs 28 View Figs 25–32. 25–26 , 101 View Figs 100–105. 100–101 ), the scutellum black, the appressed facial setae silvery and the erect propodeal setae black. Therefore, S. decipiens is more likely to be mistaken for a species of the umtalicus group or, especially in the case of male specimens, one of the meridionalis group. Still, sequence data show that it is closely related to S. jansei .

One of the most diagnostically useful characters present in both sexes of members of the umtalicus group is a densely pubescent scutellum. Species of the meridionalis - and gaullei groups only have very sparse vestiture on the scutellum. As mentioned in the introductory remarks, this can even be seen when most of the setae have been lost due to abrasion, as the scutellar impression will usually still show the original state. Additionally, members of S. decipiens ( Fig. 100 View Figs 100–105. 100–101 ) are distinguished from those of the meridionalis group by having the erect propodeal setae oriented anteriorly, as is the case for all species in the gaullei - and satanas groups. In members of the meridionalis - and umtalicus groups, the setae are more perpendicular and merely curved towards anterior ( Figs 3–4 View Figs 1–6. 1–3 ). As this can be difficult to see, though, it may be easier to rely on other characters like the singular narrow placoid present only on flagellomere V of the antenna in males of the meridionalis group, whereas males of S. decipiens have a placoid on flagellomere IV and on occasion also on parts of flagellomeres III and V.

Description

Female

SIZE. 20.4–23.9 mm.

COLOR. Black except for the following, which are ferruginous: basal half of mandible, free clypeal margin, occasionally antenna from scape up to flagellomere V and occasionally legs from distal half of femur onward. Wings uniformly fuscous, with violet iridescence.

VESTITURE. Appressed setae on clypeus and paraocular area silvery, on collar, scutum and propodeal enclosure black. Erect setae on clypeus, paraocular area, collar, scutum and propodeal enclosure black. Erect propodeal setae oriented anteriorly. Clypeus with glabrous spot in lower center. Scutellum sparsely and finely pubescent.

STRUCTURE. Free clypeal margin simple, stepped medially. Clypeus without indentation or carina. Scutellum convex. Metanotum slightly raised, not notably bituberculate. 2 nd recurrent vein joins markedly proximal from interstitium between submarginal cells II and III. Propodeal enclosure without any notable ridges. Foretarsomere I 1.7–2.0 × length of antepenultimate spine. Petiole length 1.9–2.0× its medial width.

Male

SIZE. 16.6–20.5 mm.

COLOR. Black, except for ferruginous stripe in center of mandible.Wings fuscous, with violet iridescence.

VESTITURE. Appressed setae on clypeus and paraocular area silvery, on collar, scutum and propodeal enclosure black. Erect setae on clypeus, paraocular area, collar, scutum and propodeal enclosure black. Erect propodeal setae oriented anteriorly. Lower part of clypeus glabrous. Scutellum densely and finely pubescent.

STRUCTURE. Free clypeal margin simple. Scutellum convex. Metanotum slightly raised, not notably bituberculate. 2 nd recurrent vein joins markedly proximal from interstitium between submarginal cells II and III. Propodeal enclosure without any notable ridges. Posterior margin of metasomal tergum VII convex. Posterior margin of metasomal sternum VII simple, of metasomal sternum VIII very slightly concavely emarginate. Penis valvae without conspicuous modifications. Petiole length 1.9–2.2× its medial width. Flagellomere III with narrow placoid covering it to varying extent, flagellomere IV with narrow placoid nearly covering entire length, flagellomere V with placoid absent or narrow, covering it to varying extent.

Variation

In females, antennae and legs can be partially ferruginous, and males can have the lower clypeal area more or less ferruginous.

Distribution

Southern and southwestern Africa.
