Prosorhynchus australis Szidat, 1961 is redescribed based on specimens collected from Conger orbignianus Valenciennes, 1842 caught in waters off Mar del Plata (38°08'S, 57°32'W), Argentina. Twenty one out of 32 congers examined were parasitized by P. australis (prevalence 65.62%, mean intensity 22.8, range 1-122). A number of morphological features not included in the original description justified the redescription of the species, and a detailed description of genitalia is provided for the first time. The diagnostic features used in the original description to define the species were corroborated, even after the range of measurements was broadened. Therefore P. australis is a valid species, despite not being considered in the recent literature regarding descriptions of new species in the genus.
