Differential diagnosis

The males of this species possess a very recognizable feature, which is the markedly notched posterior margin of sternum VII ( Fig. 20 View Figs 19–24. 19–20 ), a characteristic that they only share with S. bohemanni ( Fig. 19 View Figs 19–24. 19–20 ) among species with uniformly black propodeal setae. Both can easily be distinguished by the fact that the notch is only about half as deep as the visible length of sternum VII in S. bohemanni , whereas it is significantly deeper in S. abbotti s. lat., so that the posteromedian part of sternum VII is almost or entirely covered by sternum VI. While S. abbotti nivarius subsp. nov. is identical to S. abbotti abbotti in these regards, the subspecies can be delimited based on having silvery erect propodeal setae ( Fig. 89 View Figs 85–92. 85–86 ).

Female specimens look very similar to those of S. stadelmanni stadelmanni , as both have uniformly black appressed clypeal and paraocular setae. However, the mandibles and free clypeal margin of S. stadelmanni stadelmanni are to a significant extent ferruginously-colored ( Fig. 16 View Figs 13–18 ), whereas they are nearly completely black in S. abbotti abbotti ( Fig. 15 View Figs 13–18 ). Furthermore, S. stadelmanni stadelmanni is known only from eastern South Africa and southwestern Mozambique ( Fig. 99 View Figure 93–99. 93, 96 [yellow]), while S. abbotti abbotti is found predominantly in east Africa ( Fig. 92 View Figs 85–92. 85–86 [red]). Females of other species in the bohemanni group are characterized by a differently-colored luster of their appressed clypeal and paraocular setae ( Figs 14, 17–18 View Figs 13–18 ).

Description

Female

SIZE. 26.8–29.5 mm.

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

VESTITURE.Appressed and erect setae on clypeus, paraocular area, collar, scutum and propodeal enclosure black. Erect propodeal setae oriented posteriorly. Lower center of clypeus glabrous. Scutellum densely and coarsely pubescent.

STRUCTURE. Free clypeal margin medially with two broad, indistinct processes, stepped above. Clypeus with indentation in lower center, longitudinal carina in upper center barely noticeable. Scutellum convex. Metanotum not 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, very indistinctly rugose in anterior third. Foretarsomere I 2.7–3.35 × length of antepenultimate spine. Petiole length 1.6–1.8× its medial width.

Male

SIZE. 22.5–32.2 mm.

COLOR. Black except for the following, which are ferruginous: stripe in center of mandible, tergum VII and sterna VII–VIII. Wings slightly fuscous, with cyan-purple 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 posteriorly. Free clypeal margin glabrous. Scutellum densely and coarsely pubescent. Metasomal sterna II–VII 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 deeply incised, of metasomal sternum semicircular. Penis valvae dorsally open, their outer margins anteriorly and inner margins posteriorly raised into broad lobes. Petiole length 1.5–1.8× its medial width. Flagellomeres IV–VI with broad placoids covering their entire length.

Variation

Unknown.

Distribution

Eastern Africa.

Remarks

Our studies showed that the synonymisation of S. kilimandjaroensis by Turner (1918) and Berland (1927) with S. bohemanni was erroneous. The holotype of S. bohemanni is unambiguously characterized by a considerably less deeply incised posterior margin of sternum VII, as well as more narrow placoids on flagellomeres IV–VI.

Photographs of the holotype of S. abbotti have been examined. The combination of uniformly black setae on the head and thorax, a black clypeal margin and only a few red spots on the mandibles are very good indicators that this species is identical to S. kilimandjaroensis and S. neavei , especially in conjunction with the locality data. Thus, S. abbotti should become the valid name.

One female from the type series of S. kilimandjaroensis in the BMNH is not conspecific with the remainder of the specimens from the type series, but actually a member of S. nigrohirtus . Thus, its locality data are included in the list of material for that species instead of here.
