Ixodes vespertilionis Koch, 1844

Ixodes vespertilionis is a bat tick that has a very wide distribution in Europe and Asia (Guglielmone et al. 2014; Estrada-Peña et al. 2018). In continental Southeast Asia it has been recorded from Lao PDR and Thailand, with other Asian records from China, including Taiwan, South Korea and Japan (Yamaguti et al. 1971; Tanskul et al. 1983; Teng and Jiang 1991; Robbins 2005; Chen et al. 2010; Kim et al. 2011; Bush and Robbins 2012; Vongphayloth et al. 2018a). Recently, I. collaris was described from Vietnam, and it is possible that other Asian records have been confused with this species (Hornok et al. 2016).

All life history stages are illustrated in Yamaguti et al. (1971).
