- Abstract
A new species of Acanthochondria Oakley, 1927 (Copepoda, Poecilostomatoida, Chondracanthidae), parasitic in the pharynx of hagfishes Eptatretus burgeri (Girard), E. sheni (Kuo, Huang & Mok) and E. yangi (Teng), from off Taiwan is described and illustrated. The new species can be distinguished from its congeners by having the neck region longer than wide (about 2-3 times as long as wide), the moderately long protopod of leg 2 (Type E), the endopod of leg 2 as large as exopod, the cephalosome wider than long, the armature formula of antennule (1, 1, 2, 2, 9), the relatively long trunk (6.7 mm) and egg-sacs (14.4 mm). This is the first record of a parasitic chondracanthid from hagfishes. The findings may provide insights into the phylogenetic relationships and interactions among chondracanthids, hagfishes and demersal fishes, but call for further molecular studies.
