Equatoria, Bahr el Ghazal, Upper Nile, Kordofan and Blue Nile Province; specimens also taken from cattle arriving at the Halfa

Quarantine in Northern Province, but it is by no means certain that the species is established there (King 1926).

Specimens have been seen from the following localities, except Blue Nile Province, all from domestic cattle unless otherwise noted:

Upper Nile: Fangak and Ler (SVS). Maban (domestic pigs; Svs). Bor, Pariak, Malakal (SVS, HH). Akobo and Taufikia (SGC). Daga Kigille Road (Tora hartebeest; SGC).

Blue Nile: Fung District (Singa headquarters) (= Funo) (King 1926).

Bahr El Ghazal: Wau (domestic donkeys, horses and cattle; SVS, HH). Busseri (domestic horse; SVS). Fanjak (domestic dogs and cattle; SVS, HH). Galual Nyang Forest (hartebeest and sick domestic donkeys; SVS; tiang; HH). Sixty miles north of Aweil (domestic goat; SVS). Khor Shammam, Boro, near Raga, Lau, Karu, Akot, Yirol, and Peth (SVs).

Kordofan: Talodi (SVS). El Obeid (SVS and Gordon College collection).

Khartoum: Khartoum (horse; Gordon College collection). Khartoum Quarantine Station (on Darfur cattle; HH).

Darfur: Radom, Nyala, Sibdo, and Zalingei (domestic horses and cattle; SVS). Near Safaha (domestic sheep; SVS).

Kassala: Kassala and Port Sudan (SVS). Only four female specimens are known from this Province.

Northern: Quarantine Station specimens from southern cattle; SGC

Since it appears that B. decoloratus is not established in Northern Province and is very rare in Kassala Province, Sudan evidence corroborates earlier expressed beliefs that 15°N. is about the northern limit of this species. The most northern Sudan locality in which B. decoloratus commonly occurs is El Obeid, at 13°11'N. In Kassala Province, the blue tick is rare and is found, in association with either local humid coastal

situations or with cattle movements, as far north as Port Sudan, which is at almost 20°N. latitude. Small populations also exist in more humid riverside garden areas in and around Khartoum.

DISTRIBUTION

The blue tick is distributed throughout most of the Ethiopian Faunal Region, barring the northern and southern periphery of this region on continental Africa. Within its range, B. decoloratus occurs widely everywhere except in more open, dry areas, and in tropical forests. It is usually common where a fair degree of shade and humidity is present. Outlying specimens have been reported from other continents but whether these are from imported hosts or from established populations is not clear.
