FIRST RECORD OF ROCINELA AFF. AUSTRALIS (ISOPODA, AEGIDAE) IN THE PATAGONIAN TOOTHFISH DISSOSTICHUS ELEGINOIDES (PISCES, NOTHOTENIDAE) FROM SOUTHERN CHILE
An isopod of the family Aegidae. provisionally referred to as Rocinela aff. australis Schicedte & Meinert. 1879, is reported from the Patagonian tootfish Dissostichus eleginoides Smitt, 1898, from off the Biobio region, Chile. One specimen was collected, its body suboval. symmetrical, the dorsum...

Thus, if the specimen would prove to really belong to Rocinela australis, then this report would constitute the most northern record of that species.
