A new atypid species, Atypus wataribabaorum, is described using the specimens from Amami-ôshima Is., the Nansei-Isls., Southwest Japan. This is the first record of Atypus from a subtropical region of Japan. Atypus wataribabaorum has 3 segmented posterior lateral spinnerets as A. affinis and piceus, but can be distinguished from A. affinis by 1) the position of sigilla I being close to the margin of sternum, 2) having prolateral furrow on male palpal femur, 3) the presense of spines on male metatarsus IV; and from piceus by having four receptacula.
