species possessing flask-shaped glands with spermathecae confined to V), but differs from it by the cephalic displacement of the genital organs, the size of the sperm funnels and the location of the first preclitellar nephridia. An identical cephalic displacement of the genital organs, combined with ventral spermathecal pores, dorsal flask-shaped glands and possession of one pair of preclitellar nephridia, as in the new species, is observed in the northern European

. From the latter two, the new species appears different because: (1) the nephridia comprise an anteseptal part and occur preclitellarly at 7/8 rather than at 6/7; (2) compact penial bulbs are present; (3) the spermathecae are confined to V and lack any glandular formation at pore.
