The main species, in addition to Eisenia fetida, can be mentioned as Eisenia andrei (formerly considered a subspecies of the previous one); Eisenia hortensis, equally similar to the Californian red; Lumbricus terrestris, misnamed Canadian earthworm, since like the Californian it is of Eurasian distribution, being the best known species from a scientific point of view; Lumbricus rubellus, the red earthworm, used in the East as a medicinal product. In the Macroscélidae family, there is Peryonix excavatus, the Himalayan red worm, used in tropical areas for composting. And to mention an African species, also imported to Palearctic regions, we see Eudrilus eugeniae, large, but very stenoic with environmental conditions.
