| Abstract |
Baikalodrilus is a genus of armoured tubificids, endemic to Lake Baikal. The existence of organic crystals in their atria is regarded as a common characteristic apparently correlated with the abscence of genital setae. Illustrated descriptions of all 22 known species and subspecies are given and discussed in this contribution, together with an emended diagnosis of the genus and an identification key. The evolution of the genus is discussed, in connection with the unique geological history of Lake Baikal. Baikalodrilus paradoxus (Snimschikova, 1984) is probably most similar to the common ancestor of the genus. The alleged occurrence of Embolocephalus velutinus (Grube, 1879) in Lake Baikal must be disputed, while Baikalodrilus inflatus (Michaelsen, 1901) is shown to belong to the genus Baikalodrilus as a species inquirenda. |
