Studies on the genus Stenostomum O. Schmidt (Turbellaria; Catenulida). I. The status of S. anatirostrum Marcus 1945 and S. bryophilum Luther 1960.

Specimens of Stenostomum, which could be attributed to either S. anatirostrum or S. bryophilum, from Britain, Kenya and Poland have been described, and compared with published descriptions of similar material collected in Brazil and Finland. It is concluded that 5. bryophilum ought to be regarded as a synonym of S. anatirostrum. S. anatirostrum is a very variable species with a wide geographical distribution. It occurs in aquatic and damp terrestrial habitats. [ABSTRACT FROM AUTHOR]
