Based on a single male specimen caught by R H Harris in February 1923 in northern KwaZulu-Natal Province (previously known as ‘Zululand’), South Africa, Zumpt  initially described the fly as Haematobia zuluensis, but in his 1973 monograph placed it in the genus Haematobosca. No other specimens of the species have been recorded since 1923, until this publication. Taxonomic treatment of the genus Haematobosca has remained remarkably stable since the 1973 monograph by Zumpt, with only two new species described since that time, H.croceicornis from Gabon, and H. aurata from Kenya; H. alcis has also been recognized as a good Holarctic species .
One of us (Braack) in January 1984 collected one male Haematobosca near Tshalungwa Spring, and in March 1991 six more males close to another nearby freshwater spring, Magovani, both sites located in the northern region of the Kruger National Park, South Africa. Initially these flies were considered a new species because of perceived differences with the written description of H. zuluensis by Zumpt , but they were not described and published in the hope of finding females for a comprehensive description. Despite fairly intensive collections of biting flies as part of routine parasitological work in Kruger National Park over two decades, no additional specimens of this species were captured. Recent re-examination of the Kruger Park specimens and comparison with the type specimen of H. zuluensis, suggests that they belong to the same species; earlier doubts had been based on intraspecific variation in some features used in the 1973 key provided by Zumpt.
Pont & Dsouli  developed a new set of keys for the separation of Haematobosca species, but without having access to the H. zuluensis type specimen the keys were misleading and H. zuluensis was not keyed out correctly.
Because of the intraspecific variation in some morphological features used in the keys of Zumpt  and Pont & Dsouli , the species is re-described below and a revised set of keys provided.
