Abstract
For nearly 50 years the ixodid tick Hyalomma marginatum turanicum, reputedly introduced into South Africa on imported Persian sheep, has been considered identical to the Asian Hyalomma (Euhyalomma) marginatum turanicum Pomerantzev, 1946. Comparisons of this tick with the Asian H. (E.) m. turanicum and other subspecies of Hyalomma (Euhyalomma) marginatum, however, reveal that it is an old taxon, namely Hyalomma rufipes glabrum Delpy, 1949. It is hereby reinstated as Hyalomma (Euhyalomma) glabrum, and its adults are redescribed and its immature stages described for the first time. The preferred hosts of its adults are large herbivores such as zebras, gemsbok and eland, on which it occurs during summer. The preferred hosts of its immature stages are scrub hares and ground-frequenting birds, on which it is present during autumn and winter. Data on its distribution and possible disease relationships are also provided.

It was originally assumed that only two species of the genus Hyalomma Koch, 1844, namely Hyalomma (Euhyalomma) truncatum Koch 1844 and Hyalomma (Euhyalomma) rufipes Koch 1844, occurred in South Africa
He based this decision on a study of reared specimens of adult H. r. glabrum that were sent to him by Gertrud Theiler, and on some adults of H. (E.) m. turanicum originating from Iran
Summary
It was originally assumed that only two species of the genus Hyalomma Koch, 1844, namely Hyalomma (Euhyalomma) truncatum Koch 1844 and Hyalomma (Euhyalomma) rufipes Koch 1844, occurred in South Africa. I. Reinstatement of Hyalomma (Euhyalomma) glabrum Delpy, 1949 (Acari, Ixodidae) as a valid species with a redescription of the adults, the first description of its immature stages and notes on its biology. For nearly 50 years the ixodid tick Hyalomma marginatum turanicum, reputedly introduced into South Africa on imported Persian sheep, has been considered identical to the Asian Hyalomma (Euhyalomma) marginatum turanicum Pomerantzev, 1946. Turanicum and other subspecies of Hyalomma (Euhyalomma) marginatum, reveal that it is an old taxon, namely Hyalomma rufipes glabrum Delpy, 1949.
