Females have a triangular scutum with only fine punctations and with an extensive pale central area; the lateral scutal areas are dark except for one or two very small light marginal spots. The eyes are not in a depression though they may be very slightly convex. Leg segments are ringed by broad bands. Females are of medium size, approximately 5.0 mm. long and 4.0 mm. wide. The scutum is approximately 2.8 mm. long and 2.9 mm. wide.

DISTRIBUTION IN THE SUDAN

A. lepidum occurs in all Provinces except Northern, though it does arrive at the Wadi Halfa quarantine in Northern Province on cattle from the South (King 1926).

All available Equatoria Province specimens originate from Eastern District and Torit District with the single exception of a male from a tiang at Terakeka (H. H. King legit), on the west bank of the Nile.

The following Sudan locality records are all from cattle and all from the Sudan Government collection unless otherwise noted:

Bahr el Ghazal: Lau and Yirol (SWS), Guar, Gogrial Subdistrict (giraffe; "SWS), Aliab (buffalo; SWS). Akot (dying bull; SVS). Eight miles west of Yirol (head of greater bustard; SVS). I doubt that A. lepidum is widely established, if at all, in Bahr el Ghazal Province. Each collection consists of only a single male, except for one male and female from great herds of migrating cattle at Yirol, 22 April 1954 (SVS).

according to Nuttall's notes for TEE-529"Is logbook in British Museum (Natural History).

DISTRIBUTION

A. lepidum is an East African herbivore parasite and is not known to occur elsewhere. It becomes uncommon in Tanganyika but is more common locally northwards to the semidesert belt of the Sudan.

EAST AFRICA: "EAST AFRICA" (Dönitz 1909).
