40. Dermacentor taiwanensis Sugimoto, 1935 .

Oriental: 1) China (south), 2) Taiwan, 3) Vietnam (Apanaskevich & Apanaskevich 2015b).

Dermacentor taiwanensis was regarded as an Oriental and Palearctic species in Guglielmone et al. (2014), but this changed following the study of Apanaskevich & Apanaskevich (2015b), who found that Dermacentor taiwanensis has been extensively confused with the reinstated species Dermacentor bellulus, and that several redescriptions under the former name depicted specimens of Dermacentor bellulus .

Apanaskevich & Apanaskevich (2015b) stated that adults of Dermacentor sp. from Japan in Keegan & Toshioka (1957) and Yamaguti et al. (1971) represent Dermacentor bellulus, and the nymph and larva of this species were described in Kitaoka & Suzuki (1981) under the name Dermacentor taiwanensis . Apanaskevich & Apanaskevich (2015b) treated Japan as outside the range of Dermacentor taiwanensis, but Kwak (2018b) continues to list this tick as present in Japan. The opinions of Apanaskevich & Apanaskevich (2015b) are provisionally accepted here, pending reanalysis of Japanese ticks held in museums and molecular studies of new material collected in that country.
