Five specimens of a new leech were found attached to fin‐rays of the dorsal and caudal fins of Cottus bubalis. The posterior sucker is folded laterally so that it can partially enclose a fin‐ray. These small, smooth‐skinned leeches resemble Platybdella in some respects, Abranchus in others. The coelomic system consists only of dorsal and ventral lacunae, the posterior crop caeca are separate and the dermis is narrow. There are only eighteen separate ganglia between the anterior and posterior ganglionic masses.
