Resumen:
Maritrema madrynensis n. sp. is described from the Patagonian coast, Argentina, on the basis of cultivated metacercaria from the crab Cyrtograpsus altimanus and naturally obtained adults from the Kelp Gull Larus dominicanus. The new species belongs to the “eroliae complex” and can be distinguished from other related species mainly in shape, size, and distribution of the spines on the cirrus, vitellarium in a complete ring in all specimens, and its neotropical distribution. Based on morphological and morphometric features of the naturally and experimentally obtained specimens, and the trophic relationship between invertebrate and vertebrate hosts, we suggest that the crab C. altimanus acts as second intermediate host of M. madrynensis n. sp. This is the first report of Maritrema in Patagonia and the southernmost report for the genus.
