Description of Ixodes columnae sp. nov., associated with a nymphal sp. N2 and a larval sp. L1 (Acarina:Ixodidae)

Abstract

Ixodes columnae sp. nov. was described, based on the specimens of larva(Ixodes sp. L1), nymph(I. sp. N2)and adult female associated by laboratory rearing. The new species is distinguished from all other East Asian species by the columnar entasis-like hypostome through all stages. The ecological data on hosts and distributions were also given.
