Tick surveys were conducted during April 2007 in Jeju Province and along the southern coast of Gyeongsangnam and Jeollanam Provinces, Republic of Korea, to assess tick species composition and distribution, and to study tick habitat associations. A total of 58, 19, and 25 sites were surveyed in Jeju, Gyeongsangnam, and Jeollanam Provinces, respectively. Surveys were conducted using tick drags through various vegetative habitats. Habitat descriptions were recorded for each 10-m drag and analyzed to determine habitat associations for each collected species. During this survey, Haemaphysalis (Ornithophysalis) phasiana Saito, Hoogstraal and Wassef was collected at 10 sites (144 nymphs) in Jeju Province and at six sites (70 nymphs and 2 females) in Jeollanam Province (new records for both provinces), but was not collected at the 19 survey sites in Gyeongsangnam Province. Haemaphysalis phasiana was collected at elevations of 5–245 m and in or near areas that had a marked presence of pine trees as well as dry or green grasses, other herbaceous vegetation, and deciduous understory.
