(clade 4 in Fig. 1) ZooBank LSID: urn:lsid:zoobank.org:act: 9B8F7B8B-9C7F-47CF-B83F-47EFF7AB0A57 Type species: By monotypy, Ohtakiana kakidaensis Fend & Torii sp. nov. Etymology Named for Prof. Akifumi Ohtaka, in appreciation for his many contributions to the study of Japanese oligochaetes and branchiobdellidans. Diagnosis Chaetae four pairs per segment, simple-pointed, sigmoid, nodulate, with dorsal pairs slightly smaller than ventral. Pharynx eversible, with large pharyngeal glands; gut with chloragogen layer. Nephridial ducts simple, tubular. Dorsal and ventral blood vessels connected by long commissural vessels. Large midventral glands in post-clitellar segments. Clitellum one cell thick. Spermathecae 3 pairs, pores anterolateral in VI–VIII. Two pairs of testes in X–XI, two pairs of ovaries in XII–XIII, eggs mesolecithal. Gonoducts simple, plesioporous; male ducts tubular, with pores slightly anterior to ventral chaetae; female ducts are conical funnels, with pores anterior to ventral chaetae.
