Notes
The marine, littoral Bacescuella labeosa sp. nov. is characterized by the presence of copulatory apparatus unique within the Tubificidae as well as an unpaired dorsal spermatheca and external spermatophores. The definition of Bacescuella Hrabe is amended to include species with the male terminalia modified as lips and unstalked external spermatophores.
