Onychodactylus koreanus species complex

Our data indicate that Onychodactylus populations from the Korean peninsula and neighboring areas of northeast China previously treated as O. fischeri , are not related to Russian populations of O. fischeri and form a monophyletic group with O. japonicus . Onychodactylus populations from Korea and China, however, do not form a clade and are grouped into four lineages. The lineage from Jilin Province, China, is a sister clade of O. japonicus species complex, and three other lineages inhabiting the Liaoning Province of China and the Korean peninsula consist a monophyletic group which we treat here as a species complex. This complex comprises at least three highly divergent clades from Korea and China, which we consider here as separate species; two of them we describe below, the third one we treat as unconfirmed candidate species. Further taxonomic assessment of Onychodactylus populations from different areas in the Korean peninsula and northeast China is required.
