Two new species of Sycorax Haliday in Curtis, 1839 are described from Ulu Temburong National Park in Brunei Darussalam: Sycorax konopiki sp. nov. and S. tomkineana sp. nov. Both species were found resting on two frog species: Ansonia leptopus (Günther, 1872) and A. longidigita Inger, 1960. Differential diagnoses for males are included and morphological characters illustrated. Possible host associations of the new species are briefly discussed. DNA barcode sequence (COI) for Sycorax konopiki sp. nov. is also provided.

Abstract The horse fly fauna of the NE parts of the Hercynicum (36 species of 8 genera, including one ssp. and one recognized form) is relatively diverse, including 65.5 % of the Tabanid species recorded from the Czech Republic. All literature records are referred to, and 136 new localities added. The most interesting finds during our faunistic survey were the nationally scarce Silvius alpinus (Scopoli, 1763), Hybomitra arpadi (Szilády, 1923), H. kaurii Chvála & Lyneborg, 1970 and H. nitidifrons confiformis Chvála & Moucha, 1971; in spite of literature records H. lurida (Fallén, 1817) was not re-found. Atylotus plebejus (Fallén, 1817) and Chrysops rufipes Meigen, 1830 are classified as endangered species in the Czech Republic, and Glaucops hirsutus (Villers, 1789) as vulnerable.

Abstract History of zoogeographical views and actual distribution of 23 determined species of Tabanidae from three subfamilies, five tribes and 8 genera (Philoliche Wiedemann, 1828 - 4 species; Chrysops Meigen, 1803 - 3; Thaumastocera Grünberg, 1906 - 1; Ancala Enderlein, 1922 - 1; Atylotus Osten-Sacken, 1876 - 1; Tabanus Linnaeus, 1758 - 8; Haematopota Meigen, 1803 - 4; Hippocentrum Austen, 1908 - 1) mainly from Kenya are summarized, using the names of recent African countries. Tabanus sericiventris Loew, 1858 is new for Kenya. Lower taxonomical units as Tabanus insignis f. neavei Austen, 1912 and T. marmorosus ssp. congicola Bequaert, 1930 are discussed. A complete new references to all identified taxa are given.
