Intraspecific variability in Antarctic tintinnids: The Cymatocylis affinis/convallaria species group

Analyses of the morphometry of 630 loricae belonging to the described species Cymatocylis affinis and Cymatocylis convallaria retrieved from 21 samples collected in the Weddel Sea (6O-73°S) strongly suggest that both taxa, including the four formae into which C.affinis was originally divided, are me...
