Abstract

Fourteen long-legged ixodid ticks (6 nymphs and 8 larvae) were collected from Bechstein’s bat (Myotis bechsteinii) in Rochefort, Belgium. All ticks were morphologically identified as Ixodes ariadnae, based on their long legs (Haller’s organ longer than maximum diameter of tarsus I), broad palps and posteriorly reverse bell-shaped scutum with wavy surface. The DNA was extracted from these ticks, followed by PCR amplification of part of their cytochrome oxidase subunit I (COI) gene. All obtained sequences were 100% identical with each other, and with the COI sequence of I. ariadnae reported previously from Hungary and Germany. Taking into account that the collection site in the present study is close to the French border of Belgium, and migration of Bechstein’s bat is known between Belgium and France, it is reasonable to suppose that I. ariadnae also occurs in France. This is the first record of I. ariadnae in Western Europe, outside its formerly known geographical range (Central Europe).
