Abstract: | In the Moluccas five lichomolgid copepods are associated with soft corals of the genus Nephthea. Paramolgus nephtheanus, n. sp., from Nephthea chabrolii, Nephthea sphaerophora, Nephthea cupressiformis, Nephthea albida, and Nephthea galbuloides, Paramolgus prominulus, n. sp., from N. sphaerophora, N. cupressiformis, and N. albida, and Paramolgus accinctus, n. sp., from N. sphaerophora, N. cupressiformis, N. albida, and N. galbuloides are distinguished from conspecifics by combinations of several characters. These include, among others, the length of the caudal ramus, the form of the female genital segment, and the shape of leg 5 in the female. Mecra ellipsaria, n. gen., n. sp., from N. sphaerophora has only two setae on the fourth segment of the first antenna, the formula II, 2 on the third endopod segment of leg 3, and five aesthetes on the second segment of the first antenna of the male. In Metaxymolgus lumarius, n. sp., from N. galbuloides and N. cupressiformis, the two claws on the second antenna are longer than the fourth second antennal segment and the proximal inner expansion of leg 5 in the female has a thorn-like process. Metaxymolgus aculeatus (Humes & Ho, 1968) occurs on N. chabrolii, N. sphaerophora, N. cupressiformis, N. albida, and N. galbuloides. |
