NAMES HEREIN CHANGED, SYNONYMIZED OR PROPOSED *AMBLYOMMA WERNERI WERNERI Schulze, 1932 (A) is synonymized under A. nuttalli Dönitz, 1909. *APONOMMA HALLI Tendeiro, 1950, is synonymized under A. exornatum (Koch, 1844). BOOPHILUS CONGOIENSIS Minning, 1934, is synonymized under B. annu latus (Koch, 1844). HAEMAPHYSALIS TEACHII HUMEROSOIDES, a subspecies tentatively suggested by Theiler (1943B), is an elongate form of H. leachii leachii, so far as now demonstrable. HAEMAPHYSALIS MUHSAMI Santos Dias, 1954 (E), is a subspecies of H. leachii. ***HYALOMMA SCUPENSE Schulze, 1919, appears from Soviet works to have distinct biological characteristics and minor morphological characteristics intergrading with H. detritum; it is therefore indicated as a "form" of yet unknown taxonomic status. HYALOMMA IMPELTATUM Schulze and Schlottke, 1930, is considered to have priority over H. brumpti Delpy, 1946. H. erythraeum Tonelli Rondelli, 1932, is also considered to be a synonym of H. impeltatum. HYALOMMA MARGINATUM Koch, 1844, is said by Pomerantzev (1950) to be a synonym of H. plumbeum (Panzer, 1795). This matter should be investigated by independent workers. *The fact that these names have been modified or are considered synonyms has been mentioned in the preliminary publication on Sudan ticks (Hoogstraal 1954B), but the reasons for these changes are presented only in the present report. **Non Sudanese species. HYALOMMA LEWISI Schulze, 1936, is a synonym of H. truncatum, not of H. excavatum as stated by Delpy (1949B). **HYALOMMA AEGYPTIUM PUNCTATA Schulze, 1919, is considered as a synonym of H. aegyptium. **HYALOMMA ALBIPARMATUM Schulze and Schlottke, 1930, is raised from the status of a synonym of H. marginatum (= H. savignyi) (Delpy 1949B) and of H. truncatum (Feldman Muhs am 1954) to full species rank; H. impressum brunneiparmatum S. and S., 1930, is considered as a synonym of H. albiparmatum, not of H. truncatum as stated by Feldman Muhsam (1954). **HY ALOMMA HUSSAINI Sharif, 1928, is treated as a valid species (not a synonym of H. excavatum cf. Delpy, 1949B) and most probably the proper type species of the subgenus Hyalommina, the previously designated type species of which (H. rhipi. cephaloides Neumann, 1901) is no more than a misformed excavatum. **HYALOMMA TURANICUM Pomerantzev, 1946, is raised to full species rank and considered to be the same as H. rufipes glabrum Delpy, 1949. HY ALOMMINA (Subgenus): See H. hussaini above. MARGAROPUS REIDI SP. NOV. is described from males, females, and nymphs. *RHIPICEPHALUS CUSPIDATUS Neumann, 1906, is shown to be actually different from the tick described and illustrated under this name by Zumpt (1950A) in his review of this genus. RHIPICEPHALUS PSEUDOLONGUS Santos Dias, 1953 (D) is a synonym of R. longus Neumann, 1907. *The fact that these names have been modified or are considered synonyms has been mentioned in the preliminary publication on Sudan ticks (Hoogstraal 1954B), but the reasons for these changes are presented only in the present report. **Non-Sudanese species.

Two other genera, Otobius (Argasidae) and Rhipicentor (Ixodidae), occur in the Ethiopian Faunal Region outside of the Sudan and are not listed in this key. A few other genera occur in other faunal regions. Another family, Nuttalliellidae, is known only from Southwest Africa. **The peripheral differentiation of A. boueti and A. confusus is only slight and these species lack a lateral suture. 5.
