Sphex caeruleanus Drury, 1773: 74   , pl. 39 fig. 4, ♀ (holotype: ♀, Africa, Bite of Benin, destroyed?).

Sphex pulchripennis Mocsáry, 1883: 35   , ♀ (holotype or syntype: ♀, Ghana, Ashanti Region, no specific locality, TMB, not examined). Synonymized with Sphex caeruleanus   by Menke in Bohart & Menke 1976: 114.

Differential diagnosis

This species is characterized by its large size, predominantly greenish wing iridescence and uniformly black erect mesosomal setae ( Fig. 63 View Figs 63–71. 63, 67 ). All other members of the group have a body length of less than 26 mm, and most of the time their wing iridescence is mainly violet or cyan-violet. Furthermore, female specimens are identifiable through their largely black clypeus, which is often ferruginous medially near the free margin and covered with appressed silvery setae ( Fig. 67 View Figs 63–71. 63, 67 ). Sphex victoria   sp. nov. ( Fig. 35 View Figs 33–40. 33–37 ) and S. mweruensis   ( Fig. 68 View Figs 63–71. 63, 67 ), both of which sport silvery appressed clypeal setae in the female sex, have the clypeus almost or entirely ferruginous.

Males of S. caeruleanus   differ from other group members in having the width of the process at the free clypeal margin 0.15–0.2× the distance between the inner orbits at the clypeal center and concavely emarginate apically. Sphex mweruensis   is similar in the shape of its free clypeal margin and process, and can have the wings with a notable greenish iridescence as well, but is distinguishable through its silvery erect propodeal setae and because the width of the clypeal process is only around 0.1× the distance between the inner orbits.

Description

Female

SIZE. 26.6–31.7 mm.

COLOR. Black except for the following, which are ferruginous: basal half of mandible, lower part of clypeus (in most specimens), scape ventrally, foreleg from femur onward except for dark brown stripe ventrally on femur, and mid- and hindlegs from femur onward. Wings fuscous, with greenish or purplegreenish iridescence.

VESTITURE. Appressed setae on clypeus and paraocular area brassy, on collar, scutum and propodeal enclosure black. Erect setae on clypeus, paraocular area, collar, scutum and propodeal enclosure black. Erect propodeal setae oriented perpendicularly, slightly curved towards anterior. Lower center of clypeus glabrous. Scutellum densely and coarsely pubescent.

STRUCTURE. Free clypeal margin medially with broad notched tooth, stepped above. Clypeus convex, without indentation or carina. Scutellum convex. Metanotum slightly raised, not bituberculate. 2 nd recurrent vein joins interstitium between submarginal cells II and III. Propodeal enclosure without any notable ridges. Foretarsomere I 2.9–3.3× length of antepenultimate spine. Petiole length 2.2–2.3× its medial width.

Male

SIZE. 27.4–28.3 mm.

COLOR. Black except for basal half of mandible, which is ferruginous. The following can be ferruginous as well: apical half of forefemur, basal half of foretibia, apical half of mid- and hindfemur, mid- and hindtibia, and hindtarsomeres I–III. Wings fuscous, with greenish 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 perpendicularly, slightly curved towards anterior. Lower center of clypeus glabrous. Scutellum densely and coarsely pubescent.

STRUCTURE. Free clypeal margin with concavely truncated broad tooth originating behind free margin. Scutellum convex. Metanotum slightly 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 without conspecific modifications. Petiole length 2.0–2.1× its medial width. Flagellomeres IV–VI with broad placoids covering their entire length, or flagellomeres V–VI with moderately broad placoids covering their entire length.

Variation

Males of S. caeruleanus   seem to be highly variable regarding leg coloration and placoid pattern. The midleg can be ferruginous from the apical half of the femur onwards, with the hindfemur, hindtibia and first few tarsomeres also being ferruginous. Other specimens have only the inner side of the hindtibia dark ferruginous, or all legs black. Broad placoids can be present on flagellomeres IV–VI or V–VI, or narrow placoids on V–VI.

Distribution

Western to central Africa.

Remarks

Unfortunately, the holotype of S. caeruleanus   could not be located and has probably been destroyed. The original description of this species is naturally quite vague, and it does not mention the conspicuous greenish iridescence which is present on the wings. However, Menke in Bohart & Menke (1976) synonymized S. caeruleanus   with S. pulchripennis   , and we do not feel that there is enough evidence to disprove his assumption.

Regarding the identity of S. pulchripennis   , we are confident that our interpretation of the species matches that of the original author. The description mentions the female clypeus being ferruginous at the apex and the wings shining green, the combination of which is unique among the African Sphex   . Furthermore, the stated body length of 27 mm exceeds that of the other members of the group.
