| Abstract |
A tentative phylogeny of the oligochaete family Tubificidae, with emphasis on the marine representatives, is presented. The scheme is based on the morphology and arrangements of prostate glands and the setal patterns. The rhyacodriline, more or less diffuse prostates are regarded as a primitive stage in prostate evolution, preceded only by the aprostate condition assumed for the ancestor of the family. An early split of the subfamily Rhyacodrilinae supposedly led to (1) a marine branch, from which evolved the highly diverse, exclusively marine subfamilies Phallodrilinae and Limnodriloidinae, and (2) a freshwater branch, which later divided into the Telmatodrilinae, Tubificinae and Aulodrilinae. The marine subfamilies invariably lack hair setae, whereas about half of the species within the other, freshwater subfamilies possess such setae in their dorsal bundles. Some marine genera, such as Monopylephorus (Rhyacodrilinae), Tubificoides and Clitellio (both Tubificinae) are regarded as recent off-shoots from the main freshwater stock. The families Naididae and Opistocystidae are considered likely to have evolved from rhyacodriline Tubificidae, whereas Phreodrilidae, the fourth family within the suborder Tubificina, is regarded as a sister group to the Tubificidae. |
