The Lumbricidae are 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 the Holarctic region: from Canada (e.g. ''Bimastos lawrenceae'' on Vancouver Island) and the United States (e.g. ''Eisenoides carolinensis'', ''Eisenoides lonnbergi'' and most ''Bimastos'' spp.) and throughout Eurasia to Japan (e.g. ''Eisenia japonica'', ''E. koreana'' and ''Helodrilus hachiojii''). An enigmatic species in Tasmania is ''Eophila eti''. Currently, 670 valid species and subspecies in about 42 genera are recognized. ==Genera== *''Allolobophora'' *''Allolobophoridella'' *''Aporrectodea'' *''Cernosvitovia'' *''Dendrobaena'' *''Dendrodrilus'' *''Eisenia'' *''Eiseniona'' *''Eophila'' *''Ethnodrilus'' *''Eumenescolex'' *''Fitzingeria'' *''Helodrilus'' *''Iberoscolex'' *''Kritodrilus'' *''Lumbricus'' *''Microeophila'' *''Murchieona'' *''Nicodrilus *''Norealidys'' *''Octodriloides'' *''Octodrilus'' *''Octolasion'' *''Orodrilus'' *''Perelia'' *''Postandrilus'' *''Proctodrilus'' *''Prosellodrilus'' *''Satchellius'' *''Scherotheca'' 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Lumbricidae」の詳細全文を読む スポンサード リンク
