Abstract: This study aims to test how the distribution of various orders of Arachnida follows the classical subdivision of Asia and where the transitional zone between the Eastern Palearctic (Holarctic Kingdom) and the Indomalayan Region (Paleotropic) is situated. This boundary includes Thar Desert, Karakorum, Himalaya, a band in Central China, the line north of Taiwan and the Ryukyu Islands. The conclusion is that most families of Arachnida (90), excluding most of the representatives of Acari, are common for the Palearctic and Indomalayan Regions. There are no endemic orders or suborders in any of them. Regarding Arachnida, their distribution does not justify the sharp difference between the two Kingdoms (Paleotropical and Holarctic) in Eastern Eurasia. The transitional zone (Sino-Japanese Realm) of Holt et al. (2013) also does not satisfy the criteria for outlining an area on the same footing as the Palearctic and Indomalayan Realms.
