The shape and colour pattern of the fore wings immediately distinguish this species from the other two species, which either have a much more brachypterous or normal fore wing shape. The hind wing costal margin has a thick band of black sclerotization that runs nearly the entire length of the wing, which is absent in the other two species. Strong genal and pronotal rugae are present, absent in the other two species. The mesosoma is the most longitudinally compressed of the three species with the pronotum, mesoscutum and scutellum all extremely transverse and of equal length. Strong white setae are present on the occiput and pronotum. The mesoscutum is posteriorly strongly raised in lateral view; mesoscutum compressed, narrow 2.5x wider than long, without raised carinae; pronotal shoulders taper to point; wings slightly shortened, extending just beyond posterior margin of second tergite, 3x longer than wide (van Noort et al. 2021).


Named by Brues after the collector of the two type specimens, Dr Hans Heinrich Justus Carl Ernst Brauns, a medical doctor who practiced in Willomore in the Eastern Cape. The Brauns collection of Apocrita Hymenoptera was purchased by the Transvaal Museum (now Ditsong Museums of South Africa) for £1500 (Anonymous 2020, Biodiversity Explorer 2020; Kock and Krόger 1972). The Brauns collection includes over 10,600 species represented by about 70,000 specimens and approximately 900 types (Ditsong Museums of South Africa 2018). However, a number of the types could not be found in the collections held at Ditsong, (Audrey Ndaba, Collections Manager, pers. comm. 2018) and their precise whereabouts is of concern (van Noort et al. 2021).
