Morphologically, these trematodes are identical to <jats:italic>Pseudozoogonoides ugui<\/jats:italic> (Microphalloidea: Zoogonidae) from Japan. According to results of phylogenetic analysis based on 28S rDNA sequence data, <jats:italic>P. ugui<\/jats:italic> was closely related to <jats:italic>Zoogonoides viviparus<\/jats:italic>, and <jats:italic>P. subaequiporus<\/jats:italic> appears as a sister taxon to these two species. Genetic distance values, calculated based on both 28S rDNA and ITS2 rDNA, between <jats:italic>P. ugui<\/jats:italic> and <jats:italic>Z. viviparus<\/jats:italic> represents an interspecific differentiation level.
