[Redescription of Cercaria setifera F.S. Monticelli, 1914 (nec J. Müller) (Trematoda), a parasite of Conus ventricosus Hwass; comparison with various ophthalmotrichocercous cercariae from the western Mediterranean].

Cercaria setifera is a Digenean parasite of Conus ventricosus, the cercariae having been recovered from this mollusc on the French mediterranean coast. The cercaria is redescribed in this paper and various aspects of its behavior are noted. Several species of Lepocreadiid cercariae from the western Mediterranean Sea have been previously confused with Cercaria setifera. In this paper the synonyms of C. setifera are discussed. The metacercarial and adult stage are, as yet, unknown.
