Sphex conradti Berland, 1927: 145   , ♀. Syn. nov.

Differential diagnosis

Females can be recognized through a combination of having basally black mandibles, completely black erect propodeal setae and appressed silvery setae on the collar, as well as posterolaterally on the scutum ( Fig. 83 View Figs 79–84. 79–80 ). In contrast, those of S. incomptus   , S. nigrohirtus   and S. pulawskii   sp. nov. usually have the basal mandible half and the free clypeal margin medially ferruginous. Female S. nigrohirtus   have uniformly black setae on the collar, scutum and propodeal enclosure ( Fig. 84 View Figs 79–84. 79–80 ), whereas those of S. incomptus   also have the majority of the propodeal setae silvery, in addition to the silvery appressed setae on the collar and the spot posterolaterally on the scutum ( Fig. 85 View Figs 85–92. 85–86 ). Females of S. pulawskii   sp. nov. resemble those of S. camerunicus   in the color of the setae on the collar, but they are distinguished through their silvery appressed and erect setae at the posterior propodeal margin ( Fig. 86 View Figs 85–92. 85–86 ). Female S. camerunicus   are also considerably larger and have a deeper indentation on the clypeus.

Males of S. camerunicus   differ in having broad placoids that completely cover flagellomeres IV–VII, and their clypeal indentation and carina are more pronounced as well. Excepting the unmistakable S. ahasverus   , the other group members only have a narrow, often discontinuous placoid on flagellomere V. Furthermore, the valvicepes of S. camerunicus   have a concave emargination dorsolaterally ( Figs 79– 80 View Figs 79–84. 79–80 ), while this structure is absent in S. nigrohirtus   ( Figs 81–82 View Figs 79–84. 79–80 ), S. incomptus   and S. pulawskii   sp. nov.

Description

Female

SIZE. 28.1–32.2 mm.

COLOR. Black except for dark ferruginous stripe in center of mandible. Wings fuscous, with violet luster. 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 oriented posteriorly. Central third of clypeus glabrous. Scutellum densely and coarsely pubescent.

STRUCTURE. Free clypeal margin with broad, shovel-like process medially, slightly stepped above. Clypeus with notable indentation in lower center and longitudinal carina above. Scutellum convex. Metanotum not raised, not bituberculate. 2 nd recurrent vein joins markedly proximal from interstitium between submarginal cells II and III. Propodeal enclosure without any notable ridges. Foretarsomere I 2.9–3.2× length of antepenultimate spine. Petiole length 1.9–2.3× its medial width.

Male

SIZE. 25.3–30.9 mm.

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

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, on paraocular area intermixed with silvery ones. Erect propodeal setae oriented posteriorly. Central third of clypeus glabrous. Scutellum densely and coarsely pubescent. Metasomal sterna III–VI with increasingly dense fringes of black setae.

STRUCTURE. Free clypeal margin simple. Scutellum convex. Metanotum not raised, not 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 fused, inner margin flattened and dorsally raised in its apical fourth, outer margin more broadly raised. Petiole length 2.0–2.3 × its medial width. Flagellomeres IV–VII with broad placoids covering their entire length.

Variation

Unknown.

Distribution

Western and central Africa.

Remarks

This species and its synonym S. conradti   were incorrectly synonymized with S. nigrohirtus   by Arnold (1928, 1951) and Berland (1952). Our study of the types revealed that S. camerunicus   is actually a valid species. The corresponding male is described here for the first time.
