NAMES HEREIN CHANCED, SYNONYMVZED
*AMBLY OMMA WERNERI WERNERI Schulze, 1932 (A) is synonymized under
A. nuttalli Dönitz, 1909.
*APONOMMA HALLI Tendeiro, 1950, is synonymized under A. exornatum
BOOPHILUS CONGOIENSIS Minning, 1934, is synonymized under B. annu
latus (Koch, 1844).
HAEMAPHYSALIS TEACHII HUMEROSODES, a subspecies tentatively sug
gested 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.
***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 IMPETTATUM 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
*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 pre sented only in the present report.
**Non Sudanese species.
HYALOMMA LEWISI Schulze, 1936, is a synonym of H. trimcatum, 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. albi parmatum, not of H. truncatum as stated by Feldman Muhs am (1954).
**HYALOMMA 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. rhipicephaloides Neumann, 1901) is no more than a misformed H. excavatum.
**HYALOMMA TURANICUM Pomerantzev, 1946, is raised to full species
rank and considered to be the same as H. rufipes glabrum
HYALOMMINA (Subgenus): See H. hussaini above.
MARGAROPUS REIDI SP. NOV. is described from males, females, and
*RHIPICEPHALUS CUSPIDATUS Neumann, 1906, is shown to be actually
different Trom 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. Tongus 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.

*Characters in this key do not necessarily apply to species within the same genera from areas outside of the Sudan. 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.
