Figs 52, 54, 55 View Figs 49–56. 49 (yellow)

Sphex taschenbergi Magretti, 1884: 581 , ♀ (syntypes: Ethiopia, Amhara Region, Metemma, [12°57ʹ17ʺ N, 36°09ʹ19ʺ E], MSNG, not examined).

Differential diagnosis

This species ( Fig. 52 View Figs 49–56. 49 ) shares many characteristics with S. fumicatus , like black erect propodeal setae and basally infuscate but otherwise hyaline forewings. Among the African argentatus group members, this combination is found only in those two. From S. fumicatus , S. taschenbergi is distinguished through having uniformly black erect clypeal setae ( Fig. 54 View Figs 49–56. 49 ) instead of silvery ones ( Fig. 53 View Figs 49–56. 49 ) in both sexes.

Description

Female

SIZE. 22.7–28.1 mm.

COLOR. Black, femora and tibia dark ferruginous. Cellular wing area hyaline, base of fore- and hindwing infuscate. Forewing with fuscous spot beyond marginal cell.

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 crimped, oriented perpendicularly. Clypeus without glabrous stripe. Scutellum densely and finely pubescent.

STRUCTURE. Free clypeal margin simple, not stepped medially. Clypeus without indentation and carina. Scutellum convex. Metanotum raised, 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 2.1–2.3× length of antepenultimate spine. Petiole length 1.8–2.1 × its medial width.

Male

SIZE. 18.9–22.6 mm.

COLOR. Black. Cellular wing area hyaline, base of fore- and hindwing infuscate. Forewing with fuscous spot beyond marginal cell.

VESTITURE. Appressed setae on clypeus, paraocular area and collar silvery, on scutum and propodeal enclosure black. Erect setae on clypeus, paraocular area, collar, scutum and propodeal enclosure black. Erect propodeal setae crimped, oriented perpendicularly. Clypeus without glabrous stripe. Scutellum densely and finely pubescent.

STRUCTURE. Free clypeal margin simple. Scutellum convex. Metanotum raised, 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 triangular. Penis valvae without conspicuous modifications. Petiole length 2.1–2.3× its medial width.
