Anchimolgus gratus n. sp. (Copepoda: Poecilostomatoida: Anchimolgidae), associated with the scleractinian coral Lithactinia novaehiberniae in New Caledonia

Anchimolgus gratus n. sp., associated with the fungiid coral Lithactinia novaehiberniae Lesson, 1831 in New Caledonia, is distinguished from its congeners (except A. pandus Humes, 1978) by the formula III,I,5 on the third segment of the exopod of leg 4. The new species differs from A. pandus which is much smaller and in which the female genital double-somite is as long as wide.
