Abstract

This paper describes three new species of earthworms belonging to the genus Amynthas (Megascolecidae: Oligochaeta) from Thailand. They are A. turris n. sp., A. nangrongensis n. sp., and A. khaohayod n. sp. which are octothecate, quadrithecate and bithecate, respectively. They were determined to be new after comparing the three new species with the other members of their respective species groups based on their original descriptions and some reference materials from Biozentrum Grindel und Zoologisches Museum, Hamburg, Germany and the Natural History Museum, London. The new species differ from other Amynthas in their pattern of genital markings and the appearance of the male field and shape of spermathecae as well. The descriptions with illustrations of three new species are provided.
