The genus Hyalomma, bont-legged ticks, comprises 25 species that have long palps and hypostome. These dark-brown or black inornate ticks have beady eyes and banded legs, and are very well adapted to dry climates. Several species of Hyalomma transmit the Crimean-Congo haemorrhagic fever virus (Hoogstraal, 1956). Other important species include H. dromedarii in camels, H. aegyptium in tortoises, and H. marginatum and H. rutipes in cattle.
