Abstract: Cercariae of Allocreadium pseudotritoni, a trematode parasite of salamanders, develop in the sphaeriid clam, Pisidium casertanum, and have the eyespots and stylet (ophthalmoxiphidiocercaria) characteristic of this larval stage in the genus Allocreadium. Allocreadium pseudotritoni cercariae are further characterized by a flame cell formula 2[(4 + 4 + 4) + (4 + 4 + 4)] = 48, three pairs of penetration glands, cystogenous glands, and a slender unadorned tail. Maximum cercarial emergence occurs within three hours of the onset of light with large numbers from individual clams usually appearing in a single day.
