Ju-shey Ho, Wei-Cheng Liu, and Ching-Long Lin (2011) W.Six species of copepods belonging to the Lernanthropidae Kabata, 1979 were found parasitic on the gill filaments of 6 species of marine fishes of Taiwan. They are: Lernanthropodes chorinemi Pillai, 1962 on Scomberoides commersonnianus Lacepède (Carangidae); Lernanthropodes trachinoti Pillai, 1962 on Trachinotus blochii (Lacepède) (Carangidae); Lernanthropus incilis sp. nov. on Evoxymetopon poeyi Günther (Trichiuridae); Mitrapus heteropodus (Yü 1933) on Nematalosa nasus (Bloch) (Clupeidae); Sagum epinepheli (Yamaguti et Yamasu, 1960) on Epinephelus awoara (Temminck et Schlegel) (Serranidae); and Sagum folium sp. nov. on Paracaesio caerulea (Katayama) (Lutjanidae). Aside from the 2 new species, the other 4 known species were recorded for the 1st time from Taiwan. A key to the 18 species of lernanthropids occurring on marine fishes of Taiwan is provided. In this paper we propose treating Mitrapus rubiginosus (Redkar, Rangnekar et Murti 1949) as a junior synonym of M. heteropodus.

Key words: Lernanthropidae, Parasitic copepods, Taiwan, Marine fish.
