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.
