A longitudinal lateral line (latero–muscular groove) present on each side between the ventral and dorsal setal couples, or absent. Dorsal median intersetal distance (dd:u), ca 0.2 to 0.5 of the circumference of the body; genital setae or penial setae present or absent. Clitellum commencing in XII or XIII, maximally extending for five segments. Male pores ventral to lateral in XIII or exceptionally XIV. Female pores at or near the anterior border of XIV in line with the male pores or nearly so or exceptionally near the ventral midline. Spermathecal pores lateral to dorsal but never in line with the male pores, paired or dorsal median and single in VI–IX, maximally in three of these segments. Dorsal pores absent. Subneural blood vessel absent. Nephridia avesiculate. Prostates (atria) tubular, lobulate or bulbous, receiving the male ducts, or discharging with the latter but separately from them into a terminal chamber; internal epithelium surrounded by a muscular sheath outside which prostatic cells are usually present. Gizzards absent. Proandric, testes in X only; or less commonly holandric, testes in X and XI, or metandric, testes in X, Seminal vesicles projecting into XI, or more elongate, or absent. Ovisacs extending posteriorly through several segments; eggs large and yolky.
