Ticks–Japan, Ticks–Korea, Ticks–Ryukyu Islands


This publication is a revision of Ixodid Ticks of Japan, Korea, and the Ryukyu Islands by Keegan and Toshioka (1957). The tick fauna of these areas is represented by 36 species in the genera Argas, Ornithodoros, Amblyomma, Boophilus, Dermacentor, Haemaphysalis, Ixodes, and Rhipicephalus. Three species of the family Argasidae and 10 species of Ixodidae were not treated in the original edition. The additional information contained in this revision was derived from field collections and a thorough review of the literature. Keys are provided for the identification of genera and species. For each species we have given synonymy, a brief diagnosis, geographical distribution, hosts, and, if known, the biology and relationship to disease. Collection data for material actually examined or recorded in the literature are given in chart form at the end of the paper. Illustrations of 65 adults and 53 immatures are provided.
