T: Rhabdostyla inclinans ; U: Rhabdostyla invaginata ; V: Rhabdostyla libera ; W: Rhabdostyla limnophili ; X: Rhabdostyla longipes ; Y: Rhabdostyla mapuche ; Z: Rhabdostyla muscorum ; A’: Rhabdostyla patula ; B’: Rhabdostyla nebulifera ; C’: Rhabdostyla nereicola ; D’: Rhabdostyla pussila ; E’: Rhabdostyla variabilis . Diagnosis: Size about 50–77µm. Cylindrical body twice as long as wide, tapered in the posterior quarter, somewhat ventrally inclined and dorsally convex. Pellicle transversally and finely striated. Cylindrical peduncle, slightly curved with an adhesive disc. Small, arched peristomial disc, slightly prominent. Infundibulum positioned in the middle of the body and reaching the back of the body. Short and not too thick peristomial collar, slightly projected. Contractile vacuole close to the infundibulum, immediately below the peristomial collar. Long, cylindrical micronucleus, positioned longitudinally. Found in association with limnic oligochaetes of the genus Nais and Lumbriculus . Remarks: compiled diagnosis of the works of Müller (1786) , D’udekem (1864) , Korschelt (1906) , Penard (1922) , Kahl (1935) , Nenninger (1948) , Stiller (1971) and Foissner et al. (1992) .
