Species belonging to the genus Pheretima have a clitellum, which is a band of glandular tissue present on segments 14 to 16.

Individuals are hermaphroditic and reproduction can be either sexual or parthenogenetic. Female genital pores lie on the ventral surface of segment 14. A pair of male gential pores is situated ventrally on segment 18. Genital papiliae may also be present ventrally. As with all earthworms, development of young is without a larval stage and takes place in cocoons.
