Elongate rectangular to oval dorso-ventrally flattened body. With 2 rows of marginal cirri and 3 rows of ventral cirri extending into the frontal region.

Jankowski (1979) created a new genus Pescozoon for T. (Balladyna) euplotes (Dragesco, 1960) Borror, 1972. He also noted that the correct and original spelling is Trichototaxis not Trichotaxis as is commonly used. Borror (1979) submerged the genus in Keronopsis.
