Abstract

Cephalobus aff. quinilineatus (Shavrov, 1968) Anderson and Hooper, 1970 and Eucephalobus hooperi MarinariPalmisano, 1967 from the family Cephalobidae Filipjev, 1934 (Cephalobomorpha) are newly reported from South Korea. Cephalobus aff. quinilineatus is distinguished from other Cephalobus species by its high and rounded labial probolae and five lateral incisures, with three incisures extending to the tail terminus. Eucephalobus hooperi is distinguished from other Eucephalobus species by its three bifurcated labial probolae with pointed termini and by morphometric characters such as body and tail length and the corpus:isthmus ratio. In this study, the morphological characters and morphometrics of C. aff. quinilineatus and E. hooperi Korean population are described and illustrated based on optical and/or scanning electron microscopy.
