See text Bdellocephala is a genus of freshwater triclad that inhabits different regions of Eurasia.

[2][1] As in other genera of the family Dendrocoelidae, species of Bdellocephala have an anterior adhesive organ.

However, differently from other dendrocoelids, species of Bdellocephala lack a well-developed penis papilla in the male copulatory apparatus, which is uncommon in freshwater planarians.
