Mitinokuidrilus excavatus n. g., n. sp., a Marine Tubificid (Oligochaeta) with a Unique Mode of Reproduction
Mitinokuidrilus excavatus n. g., n. sp. is described from shallow subtidal coarse sands in northern Japan (NW Pacific). The species is characterized by a unique mode of sexual reproduction. Each of the two types of mature worms represents the opposite sex: “male” worms have testes, seminal vesicles,...

| description | Mitinokuidrilus excavatus n. g., n. sp. is described from shallow subtidal coarse sands in northern Japan (NW Pacific). The species is characterized by a unique mode of sexual reproduction. Each of the two types of mature worms represents the opposite sex: “male” worms have testes, seminal vesicles, male ducts and small spermathecae; “female” individuals possess clitellum, ovaries, ovisac, female ducts and fully developed spermathecae. No mature worms with intermediate sexual condition were collected. The taxonomic position and the possibility of consecutive hermaphroditism of the present species are discussed. |
