On some problems related to the occurrence of Pseudobenedenia nototheniae Lohnston,1931 (Monogenea, Capsalidae, Trochopodinae) off the South Shetlands

Abstract

Parasites of six Notothenia species were studied in 1979 at the Polish Academy of Sciences H. Arctowski Station on the South Shetlands. Only two fish species, namely, Notothenia coriiceps neglecta and N. rossi marmorata , showed the presence of external parasites, Pseudobenedenia nototheniae Johnston, 1931. A number of observations have been made on the parasite's morphology. Evidence in support of Gibson (1976), who regards P. lauriei Szidat, 1965 as synonymous with P. nototheniae Johnston, 1931, is given
