Many, see text Pheretima is a genus of earthworms found mostly in New Guinea and parts of Southeast Asia.
Species belonging to the genus Pheretima have a clitellum, which is a band of glandular tissue present on segments 14 to 16.
As with all earthworms, development of young is without a larval stage and takes place in cocoons.
They are also called farmer's friend as they help in making the soil porous for easy irrigation.
Similar genera include Amynthas, Archipheretima, Duplodicodrilus, Metaphire, Metapheretima, Pithemera, and Polypheretima.
