Ryuthela is a spider genus in the family Liphistiidae.[1] This genus, as well as their closest relatives, Heptathela, formed when land masses from present-day Japan separated from the rest of Asia, forming islands in the late Miocene. Speciation of Ryuthela and Heptathela also occurred during this time, because of the further separation of islands, causing allopatric speciation.[2]
