H. Fufipes is widely spread in the Sudan but is numerous only

in the semiarid central area.

The following are localities from

which specimens (all from cattle unless otherwise noted) have been


Bahr El Ghazal: Galual-Nyang Forest (Very common on buffalos and giraffes; SVS, HH. The absence of this tick on the numerous tiang examined in this area is notable). Aliab (buffalos; SVS). Lau £ Lake Nyubor, Boro, Khor Shammam, and near Raga (SVS). Yirol (horses; SVS).

Upper Nile: Bor, Ler, and Fangak (SVS). Malakal (HH).

Blue Nile: Common at Wad Medani (HH). Abu Zor, Hosh, near Ethiopian border, and Lake Ras Amer (camels and cattle; SGC).

Kordofan: "Western Jebels" and Umm Inderaba (SVS).

Darfur: Nyala, Zalingei, Radom, Sibdo, Muhagariya, and Sahafa (common on camels, cattle, sheep, and horses; SVS).

Kassala: Kassala (camels and cattle; SVS). Port Sudan (SVS).

Khartoum: Khartoum: Numerous specimens have been collected from sheep, goats, and horses, but few from cattle (HH). At the Khartoum quarantine station many adults are found on Darfur and Kordofan cattle. The Sudan Government collection contains a series of adults reared from nymphs from a kite, Milvus migrans, by H.H. King, 20 September 1922.

Northern: Shendi (camels and donkey; SVS). Wadi Halfa (camels; SSC, HH).


H. rufipes is widely distributed in many drier parts of Africa but it is quite localized and seldom very common in any locality. The hairy hyalomma is not known from many of the more westerly areas of Africa. It is present in the Yemen (Southwestern Arabia); and in North Africa occurs in Egypt and Libya but is not known further West on the Mediterranean littoral.

Elsewhere, H. rufipes occurs in Palestine, Iraq, Eastern Ana

tolia, and Russia (Transcaucasia, Astrakhan, Kazakhstan). Soviet workers find H. rufipes in such small numbers and in such scattered

localities that Pomerantzev (1950) believes its presence in Russia is due to small local populations established from nymphs from migrating birds. Schulze (1918) reported a Macedonian specimen (as H. impressum) that may have been imported on a bird.

This distributional picture is indeed unique, and it may be surmised that H. rufipes is a species of the Ethiopian Faunal Region that has extended its range beyond these confines as a result of transportation by migrating birds, which are important hosts of immature stages (page 486).

NOTE: The record of H. impressum rufipes from China (Chodziesner 1924) probably refers to a heavily punctate H. marginatum (Kratz 1940). H. rufipes has been stated to occur in Portugal by Kaplan and Hulse in their review of prevalence of Q fever in Europe; this apparent error derives from the report by Fonesca, Pinto, Colacao, Oliveira, Branco, da Gama, Franco, and Lacerda (1951) that "H. rufipes glabrum" is associated with Q fever there. This is assumed to #: o H. marginatum.


Domestic cattle appear to be the most common hosts of this tick. They are mentioned by practically every author and are the most frequent hosts of specimens in museum collections. Other common domestic hosts are horses, sheep, and goats. Bedford (1932B) states that dogs and cats are also infested; specimens from these hosts are present in British Museum (Natural History) and HH collections. In semidesert areas, camels are frequently parasitized (Sudan records; HH mss.; numerous Somaliland specimens in BMNH collections; Hoogstraal 1953D). Among wild animals, the buffalo and giraffe are common hosts, as is the rhinoceros. Antelopes and certain birds are less common hosts
