Revalidation of the stygobiotic species Haber zavreli (Hrabe, 1942) (Clitellata, Naididae, Tubificinae) with discussion on the closely related species Haber speciosus (Hrabe, 1931) and Haber monfalconensis (Hrabe, 1966)

During studies of aquatic fauna in wells situated near Krakow (South Poland), many specimens of clitellates were found. The detailed description of the setal formula and genital organs of the collected individuals made it possible to distinguish Haber zavreli (Hrabe, 1942) from the related species: H. speciosus (Hrabe, 1931) including synonymized H. simsi and its forms known from the USA (H. speciosus simsi and H. speciosus fluminialis) and H. monfalconensis (Hrabe, 1966). In addition, remarks concerning the morphologically similar Haber vetus (Semernoy, 1982) described from Lake Baikal and the stygobiotic species H. turquinae (Juget & Lafont, 1979) are included.
