Remarks.

Originally described as Axine elongata by Meserve (1938) from gills of Caranx melampygus (misidentified as Xurel malampygus ). Price (1962) proposed the genus Cemocotylella to include A. elongata , changing the name of this species to C. elongata . Axine elongata ( Meserve 1938) and Heteraxine elongata ( Meserve 1938) Sproston 1946 are considered synonyms of C. elongata . This species is characterized by having an asymmetrical posterior haptor, four to five suckers on the short side and 24-25 on the long side, an unarmed genital atrium and MCO, and he absence of a vagina. The presence of C. elongata on Caranx papuensis from off Palmyra Atoll represents both a new host and a new geographical record.
