Australasian: 1) Indonesia (east of Wallace’s Line); Oriental: 1) Cambodia, 2) China (south), 3) India, 4) Indonesia (west of Wallace’s Line), 5) Japan (the Ryukyu Islands), 6) Laos, 7) Malaysia, 8) Myanmar, 9) Nepal (south and central), 10) Philippines, 11) Singapore, 12) Taiwan, 13) Thailand, 14) Vietnam; Palearctic: 1) China (north), 2) Japan (except the Ryukyu Islands), 3) South Korea ( Kohls 1950b, Yamaguti et al. 1971, Hoogstraal et al. 1972 a, Tanskul et al. 1983, Robbins 2005, Durden et al. 2008, Kolonin 2009, Chen et al. 2010, Takano et al. 2014, Kuo et al. 2017, Kwak 2018c, Pun et al. 2018, Vongphayloth et al. 2018 a, Petney et al. 2019).

Clifford et al. (1975a) reclassified as Ixodes near redikorzevi specimens identified by Hoogstraal (1970c) as Ixodes granulatus , but there is a bona fide record of this tick from Nepal, and Pun et al. (2018) consider Nepal within the range of Ixodes granulatus .

Estébanes-González & Cervantes (2005) recorded Ixodes granulatus from southern Mexico (Neotropical), but Guzmán-Cornejo et al. (2007) treated these records as misidentifications, and Mexico is excluded from the geographic distribution of Ixodes granulatus .

Important molecular differences within populations of Ixodes granulatus from China, Japan and Malaysia have been found by Lah et al. (2016). Such results may indicate that more than one species exists under the name Ixodes granulatus .
