Abstract

Terrestrial megadrile earthworms variously reported from Taiwan including Lanyu Island (Botel Tobago) number approximately 70 species with 29 of these, or 40%, non-natives for which 69% are Asiatic Megascolecidae and 21% are Lumbricidae of Holarctic origin. An additional 27 unnamed species have been identified from Ilan county north-eastern Taiwan by Chen et al. (2003) that, if published, would bring the total to around 100 known species. The checklist is also provided with the confirmation and new records of the exotic lumbricids Eisenia fetida (Savigny) and Eiseniella tetraedra (Savigny).
