Abstract

Pheretimoid earthworms, Amynthas carnosus, were collected from Northeast and North China. An update on the distribution and systematics of the A. carnosus complex in eastern Asia using both morphological and molecular data is provided. Three subspecies, A. carnosus carnosus, A. carnosus naribunji, and A. carnosus roki, are confirmed. Comparisons of morphological characters between the subspecies of A. carnosus are provided. Our results support the subspecies assignment with an intraspecific K2P genetic distance of not greater than 10% using the mitochondrial cytochrome c oxidase subunit I (COI). In addition, a re-description of the morphology of A. carnosus naribunji is presented here.
