E: Female posterior part; F~ I: Oriverutus pagarus ; F: Anterior part; G: Female tail; H: Oesophagus-intestine junction; I: Male posterior part; J: Female gonad. Discussion. The measurements and other characters are similar to E. hopedorus but in the Korean specimens the odontophore does not show basal flanges. Localities and habitat . Chiri Mt.
