摘　　要：The small subunit rRNA （SSrRNA） gene was sequenced for two marine scuticociliates Metanophrys sirnilis and Pseu-ocohnilembus hargisl. The results show that this gene comprises 1763 and 1753 nucleotldes in the two marine ciliates respectively. Metanophrys similis is phylogenetically closely related to the clade containing Mesanophrys carcini and Anophyroides haemophila, which branches basally to other species within the order Philasterida. Pseudocohnilembus hargisi groups with its congener, P. marinus, with strong bootstrap support. Paranophrys magna groups with the clade including Cohnilembus and Uronema, representing a sister clade to that containing the two Pseudocohnilernbus species.The small subunit rRNA (SSrRNA) gene was sequenced for two marine scuticociliates Metanophrys similis and Pseudocohnilembus hargisi.
