The types of Hottentotta species described by A. A. Birula and deposited in the Zoological Institute, Russian Academy of Sciences, St. Petersburg, Russia are revised. The types of H. buchariensis (Birula, 1897), H. niloticus (Birula, 1928), H. penjabensis (Birula, 1897) stat. nov. and H. schach (Birula, 1905) are fully illustrated with color photographs of morphology. Their taxonomic position is discussed. Lectotypes are designated for H. niloticus and H. schach. We confirm synonymy of Buthus (Hottentotta) minax niloticus Birula, 1928 (Sudan) with Buthus minax L. Koch, 1875, syn. n. Two new species, Hottentotta juliae sp. n. from Iran (Fars Province) and H. krivokhatskyi sp. n. from Pakistan (Balochistan Province), are described, based on specimens which were in previous publications incorrectly identified as H. schach and H. penjabensis.
