Two leech species were found parasitizing the shrimp Cryphiopscaementarius from Limarí river, Chile. These ectoparasites can act as population regulators or developmentinhibitors in their host; however the biological characteristics of this host-parasite interaction are unknown. Weanalyze the inter-specific differences of the parasitism and its relation with host size and sex using quantitativedescriptors. Abundance, prevalence, intensity and range were estimated with respect to host size and sex. Theleeches belong to two species of Glossiphonidae: Helobdella triserialis and H. duplicata. Forty-seven percentof the hosts were parasitized by one or both leech species. H. triserialis was found only in the pleopod of thehosts with the highest prevalence values (42 %), intensity (2.9) and range (1-11). H. duplicata was found onlyin the branchial filaments with 7 % prevalence, an intensity of 1.7 and a range of 1-4. The hosts total lengthand sex can explain the variation in leech intensity and infection prevalence. However, when only the hosts sexis considered, prevalence only increased with size in female hosts. Morphological characteristics of the femalescould explain the greater H. triserialis intensity in the base of the pleopod and would be related to a greaterabdomen development. Rev. Biol.
