Megascolecidae earthworm Amynthas japonicus ^[2] is an extinct Japanese native probably collected from Nagasaki in the 1820s. ^[1] It was one of three native earthworms ^[3] featured in Dr P.F.B. von Siebold's extensive collection and recorded as one of Japan's earliest pheretimoid species. ^[4] It is now deemed extinct given that a 2018 Nagasaki expedition and earlier 1930s reports failed to locate it. ^[5] It is featured on The Recently Extinct Plants and Animals Database. ^[6]
