Abstract

This paper describes two new species of terrestrial earthworms belonging to the genus Amynthas from northern Laos; A. panhai sp. nov. and A. oudomxayensis sp. nov., are described based on external morphology and anatomy. They were determined to be new species after comparison 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, and Chulalongkorn University, Museum of Zoology, Thailand. However, they differ from all other known species of Amynthas by a combination of the following characters: male field and genital marking pattern, shape of spermathecae, and prostate gland and duct.
