Silva, P. H. D. H. de.; Kabata, Z. (1961). A new genus and species of leech parasitic on Drepanopsetta platessoides (Malm) the long rough dab. Proceedings of the Zoological Society of London. 136(3): 331-341.
This new piscicolid leech (subfamily Ichthyobdellinae) was found attached to the branchiae and inner surface of the branchial chamber of Drepanopsetta platessoides, trawled off Iceland. It has a fairly extensive coelomic system with no clear separation into dorsal, ventral and segmental lacunae. Its posterior crop caeca are separate and there are only eighteen separate ganglia between the anterior and posterior ganglionic masses.
