For Razouls (1968 a, p. 154) the descriptions of Farran and Sars show differences on the number of articles of antennae ( A1). These differences are due to a segmentation only sketched on certain segments. The antennae of the individual collected to Banyuls seems closer to that of the specimen of Farran. the chetotaxy of the 2nd segment of endopodites differs strikingly from that observed by Farran for P1 and P2, but this last author is not sure of his observation. My own observations suit to those of Sars for P1, P3 and P4 but differ for P2 where appear only 5 setae. The presence of this rare species in the Mediterranean Sea, with Diaixis hibernica and Paraeuchaeta norvegica suggests the hypothesis of species glacial relicts. Oithona parvula observed off the northwest coast(ribs) of Ireland ( Farran) and on the coast(ribs) of Norway ( Sars) completes the list of these species of Atlantic boreal origin present it. | | | Last update : 25/10/2022 | |
