Abstract

In a survey to increase the knowledge about parasites of fishes in brackish waters of Argentina, we found adult specimens of Diphterostomum brusinae parasitizing the gut of juveniles of the whitemouth croaker, Micropogonias furnieri (Sciaenidae), in Bahía Blanca estuary (N=142) and in Samborombón Bay (N=265) (Buenos Aires Province, Argentina). Prevalence (P) and mean intensity (MI) were higher in the first site (P = 18.3 % vs. 14.7 %; MI = 18.9 vs. 6.7). Measurements and morphology of specimens fits with the description previously made for D. brusinae. Adults typically have a densely spiny tegument, two small and sacular intestinal caeca, and a well-developed ventral sucker with two pairs of muscular lips. In Samborombón Bay we also found larval stages (sporocysts, cercariae, and metacercariae) parasitizing the intertidal snail Buccinanops globulosus (Nassariidae). The morphology and measurements are also coincident to those described for larvae stages of D. brusinae. In this work we record for the first time D. brusinae in M. furnieri from Argentina and partially propose the life cycle of this species in Samborombón Bay, Argentina.
