Nucleotide sequences for the 18S rDNA (1 720 bp) of 11 ostracoda species, representing 3 superfamilies and 5 families, were analyzed based on maximum parsimony (MP) and neighbor joining (NJ). The topologies of phylogenetic relationships gained by two analytic methods are similar. The results shown: 1) Cypridocopina forms a monophyletic group; 2)Close rationship between Pontocypridoidea and Macrocypridoidea can be postulated; 3)Cypridoidea is considered as a monophyletic group, but the rationships among cypridoidean families could not be resolved from 18S rDNA.
