On the identity of Chamaedrilusglandulosus (Michaelsen, 1888) (Clitellata, Enchytraeidae), with the description of a new species.

ABSTRACT: The taxonomy of Chamaedrilusglandulosus (Michaelsen, 1888) s. l., most commonly known previously as Cognettiaglandulosa, is revised. A recent molecular systematic study has shown that this taxon harbours two cryptic, but genetically well separated lineages, each warranting species status. In this study these two lineages are scrutinized morphologically, on the basis of Michaelsen's type material as well as newly collected specimens from Central and Northern Europe. Chamaedrilusglandulosus s. s. is redescribed and Chamaedrilusvarisetosus sp. n. is recognized as new to science. The two species are morphologically very similar, differing mainly in size, but seem to prefer different habitats, with Chamaedrilusglandulosus being a larger aquatic species, and Chamaedrilusvarisetosus being smaller
