2.7.1 Haemaphysalis spinigera
Neumann first described this species in 1897 on the basis of adults collected from
Sri Lanka. Nuttall and Warburton repeated the same description and illustrations in
1915 and by Sharif in 1928. This is a tick species that has been studied more
exhaustively than any other tick species in India as this is the main vector of KFD,
the only tick-borne human viral disease in India (
