These gill flukes are small, only a few mm in length. The most noticeable feature is the posterior opisthaptor, visible at the bottom of the photo. The opisthaptor has two pairs of large anchors, or hamuli. These allow the fluke to attach securely to the gill filaments. Since the opisthaptor is a non-replicated structure, it easily places this fluke in the Monopisthocotylea.
There are several, dark-staining head organs at the anterior end of the worm that form a prohaptor. By alternately attaching with opisthaptor and then prohaptor, the parasite can move from one filament to another. The prohaptor in this species is not associated with the mouth. Posterior to the prohaptor are two pairs of small, dark eyespots. The posterior eyespots are located on the margins of a circular, muscular pharynx which surrounds the mouth. There are two lateral bands of vitellaria which stain vary darkly, and in the middle of the body between the bands of vitellaria are two lighter-staining oval structures. The anterior one is the ovary and the posterior one is the testis.
