Lumbricidae

The Lumbricidae is a family of earthworms which includes most of the earthworm species well-known to Europeans. About 33 lumbricid species have become naturalized around the world , but the bulk of the species are in Holarctic: from Canada and the United States and throughout Eurasia to Japan ....

Note that *Lumbriculus lineatus and *Lumbriculus codensis, which are sometime seen on the internet, do not exist; both species belong to the Enchytraeid genus Lumbricillus, and ITIS (and other similar reports) have simply written the wrong genus. The old genus Thinodrilus is presently considered to be a part of Lumbriculus, but may have subgeneric status. If so, it contains (at least) the species L. ambiguus, L. inconstans and L. genitosetosus. The status of many of the Lumbriculus species listed above is uncertain.
