Haemaphysalis obesa Larrousse, 1925

This is an Oriental species with a relatively broad distribution, ranging from eastern India eastward to Cambodia, northern peninsular Malaysia, Thailand, and Vietnam (Hoogstraal et al. 1966, 1971a; Tanskul et al. 1983; Hoogstraal and Kim 1985). It is found in dense, humid lowland forests where it has been collected from a wide variety of mammal species. Adults have been reported from Bovidae (including cattle and water buffalo), Cervidae , Cercopithecidae ( Presbytis pileatus ), Suidae , Tapiridae and Ursidae ( Hoogstraal et al. 1971a). Immatures have been reported from Canidae ( Cuon alpinus ), badger and humans ( Kolonin 2009). Hoogstraal et al. (1971a) provide information on the life cycle of this species based on Indian and Thai populations. There were considerable differences between developmental times that may be related to differences in hosts, humidities and temperatures under experimental conditions.

The adults are described by Hoogstraal et al. (1966), and the immature stages by Hoogstraal et al. (1971a). Guru et al. (1976) describe cell cultures derived from developing adults of Ha. obesa .
