Ju-shey Ho and Ching-Long Lin (2006) Two species of Makrostrotos gen. nov. (Copepoda: Taeniacanthidae), M. acuminatus sp. nov. and M. hamus sp. nov., were discovered parasitic on the gill filaments of the laced moray, Gymnothorax favagineus Bloch and Schneider, caught and landed at fishing ports in southern Taiwan. The new genus is characterized in having a T-shaped (instead of a Y-shaped) rostral bar, a robust, prehensile maxilla, and a whiplike maxilliped. The 2 new species of Makostrotos can be distinguished by the structure of the terminal claw on the maxilla and the armature of the 3rd expopodal segment of leg 4.

Key words: Taeniacanthidae, Copepoda, Makrostrotos, Taiwan, Marine fish.
