The species of the genus Haemaphysalis occurring in the USSR fauna can be divided into several zoogeographical groups. H. concinna, a relict species, developed in the warm, humid climate of the Tertiary period. This species occurs in western Europe, Iran, and southeastern Asia in USSR in Primorye, Zakavkazye and Crimea. South Asian inhabitants, H. neumanni and H. japonica douglasi occur in the humid forests of Primorye. H. warburtoni, an element of the eastern fauna occurs in mountains of Kirgizia and Altai, and in a limited area of the Caucasus. H. inermis is found in western Europe and Iran and in the USSR in Crimea, along the Black Sea coast of Caucasus, in Ciscaucasia, and in the mountain forest area of Georgia. H. sulcata is distributed from Mediterranean coasts throughout Iran to Central Asia and India in the USSR it is found in Crimea, Transcaucasia, Ciscaucasia, and Central Asia, where it is numerous in foothills and along river valleys. H. otophila inhabits the Balkans and Asia Minor. H. punctata is found in Europe, North Africa, Asia Minor, and Iran in USSR this species penetrates further north than others, to about 50 deg. latitude. During the isolation process of the last 3 species, it is very important that their immature forms develop chiefly on different animal groups those of H. punctata on birds, of H. sulcata on reptiles, and of H. otophila on mammals. H. numidiana occurs in North Africa, Asia Minor, and Iran in USSR it is found in Crimea, seldom in Caucasus, and very commonly in Central Asia and Kazakhstan.
