Amynthas japonicus explained

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