Parasitological analysis of 554 specimens of Fissurella limbata Sowerby, 1835 (Mollusca, Archaeogastropoda) showed that as many as 97% of the molluscs were infected in the gonads by progenetic adults of the digenetic trematode Proctoeces lintoni Siddiqi et Cable, 1960. Prevalence and intensity of infection were not affected by the host’s sex, but were significantly and positively correlated with host length. Season seemed to affect neither, intensity nor prevalence of infection. Mean intensity reached 16.4, maximum intensity observed was 90 worms. The impact of microhabitat in a rocky beach is discussed as a possible factor that may help to explain the strong differences found in prevalence and intensity of infection caused by Proctoeces lintoni in Fissurella spp. from Chile.
