A genus of small, eyeless, inornate ticks. As larvae and nymphs, they are found chiefly on small mammals and birds; as adults, they are found on larger mammals and some birds. They are important as vectors of protozoa and viruses, (e.g., Kyasanur Forest disease virus). [G. haima, blood, + physaleos, full of wind]

- H. cinnabarina a tick that occurs chiefly in the dry district of British Columbia; this species can cause tick paralysis in both humans and animals. [G. kinnabarinos, like cinnabar, vermilion]

- H. concinna common rodent tick species of the area formerly known as the U.S.S.R. that is a vector and reservoir of tick typhus.

- H. leachi a species of Africa, Asia, and Australia that occurs on domestic and wild carnivores, on small rodents, and occasionally on cattle; it transmits canine babesiosis and boutonneuse fever.

- H. spinigera a tropical forest species in India that is a vector of Kyasanur Forest disease; various rodents and insectivores serve as hosts of immature ticks of this species, which carry an arbovirus of the Russian spring-summer B group complex; monkeys act as reservoirs of human infection.
