Abstract

During the study of the enchytraeid fauna of South Korea, specimens were found, which were identified as Bryodrilus ehlersi based on their morphological characters. This was an unexpected result since this species is common in Northern and Central Europe but has not yet been found in the Far East. Furthermore, sequence analysis of the mitochondrial cytochrome c oxidase subunit I gene, the nuclear histone 3 gene and the nuclear ribosomal ITS region showed unambiguously that the specimens collected in South Korea represent a different evolutionary lineage. In this paper, the detailed morphological and molecular comparison of Bryodrilus ehlersi specimens collected from various sites and countries are presented. Although the Korean specimens could not be formally described as a different species due to the lack of studied specimens from the type locality, clear evidence of cryptic genetic diversity was found within Bryodrilus ehlersi.
