DNA barcoding of two marine tintinnids, Eutintinnus rectus and Schmidingerella arcuata, was performed using four samples collected from different sites in the north-eastern coast of South Korea. The loricae morphology was observed by light and scanning electron microscopy. Molecular data were analyzed using five nuclear ribosomal DNA markers(18S, ITS1, 5.8S, ITS2, and 28S genes) and one mitochondrial marker (CO1 gene). The intraspecific pairwise differences of E. rectus and S. arcuata in the CO1 gene were 0.0-0.2% and 0.0-0.6%, respectively, while there were no differences in the 18S rDNA sequences.
