48. Amblyomma geoemydae (Cantor, 1847). Oriental: 1) Cambodia, 2) China (south), 3) India, 4) Indonesia (west of Wallace’s Line), 5) Japan (the Ryukyu Islands), 6) Malaysia, 7) Myanmar, 9) Philippines, 10) Singapore, 11) Sri Lanka, 12) Taiwan, 13) Thailand, 14) Vietnam; Palearctic:1) Japan (except the Ryukyu Islands) (Yamaguti et al. 1971, Tanskul et al. 1983, Kolonin 1995b, Yabe & Hayashi 1998, Robbins 2005, Robbins et al. 2006, Chen et al. 2010, Burridge 2011, Petney et al. 2019, Chao et al. 2022). Several records of Amblyomma geoemydae have been published under the names Amblyomma caelaturum, Amblyomma formosanum and Amblyomma malayanum, all synonyms of Amblyomma geoemydae, as discussed in Guglielmone & Nava (2014). Kwak (2018c) treated the record of Amblyomma geoemydae from Singapore as unsubstantiated, but Neumann (1908a) described Amblyomma malayanum, a synonym of Amblyomma geoemydae, as discussed in Guglielmone & Nava (2014), from ticks collected in Singapore. Chen et al. (2010) listed Amblyomma geoemydae as present in China, but Zhao et al. (2021) do not include this tick in their list of Chinese ticks. Both Singapore and China are included here within the range Amblyomma geoemydae. Qiu et al. (2021) included Australia within the geographic distribution of Amblyomma geoemydae, but this tick has not been found there. Takano et al. (2014) found molecular differences between populations of Amblyomma geoemydae from the Ryukyu Islands, indicating that more than one species may exist under this name.
