  • ISSN : 0304-0798



This paper reviews the Tabanidae known to occur in Africa south of Moçambique, Rhodesia and Angola. All the species are listed, the localities in which they have been found are grouped according to a system of climatic regions, and the distribution data are summarized in table form. There is a commentary on the nature and composition of the tabanid fauna, and data are presented for each climatic region detailing the number of species present, degree of endemism and extent to which the different tribes are represented. The geographical source of Wahlberg's material and the course of his travels are discussed, and it is shown that he did not collect in the south-eastern part of the Cape Province once called 'Kaffraria'. Conclusions are drawn regarding species density, areas of endemism, geographical features associated with endemic taxa, discontinuities in the tabanid fauna, and the thoroughness of collecting. The following new synonymies are established: Philoliche (Buplex) leucomelas (Wied.) 1828 = Buplex albicinctus Austen 1937; Philoliche (Ommatiosteres) caffra (Macq.) 1847 = Pangonia ramulifera Loew 1863; Braunsiomyia cinerea (Surcouf) 1921 = B. tigrina Dias & Sousa Junior 1957; Haematopota albihirta Karsch 1877 = H. diasi Dias 1956, and H. tropai Dias 1956.
