Haemaphysalis anomala Warburton, 1913

Haemaphysalis anomala occurs in elevated areas ranging from 240 m to 1,220 m above sea level, and in an arc from the hills of Bihar and Assam through southern Nepal and the mountains of northwestern Thailand into Cambodia and Vietnam; it also occurs in Sri Lanka (Hoogstraal et al. 1967, 1972a). The hosts of adults include carnivores, artiodactyl mammals (cattle, water buffalo and goats), rats and humans (Hoogstraal et al. 1972a). The immatures were described by Hoogstraal et al. (1972a) from greater coucal ( Centropus sinensis) and Rattus spp. Limited data from northern India suggest that adults are active during the June to September monsoon period and immatures pre- and post-monsoon (Hoogstraal et al. 1972a). This species appears to have withstood the change from forest to agricultural habitat by adapting to cattle and buffalo as hosts in what was previously moist deciduous forest above 240 m in northern India (Hoogstraal et al. 1972a). These authors also provide laboratory data on the life cycle of an Indian population of this species.

The male and female are described in Hoogstraal et al. (1967), the immature stages in Hoogstraal et al. (1972a).
