Abstract
Six new copepods are associated with five species of the antipatharian coral Antipathes in the Indo-Pacific. Three asterocherid siphonostomatoids are described. Asteropontius latus sp. nov., from Antipathes sp. at Bohol Island, Philippines, has an unusually broad prosome. Asteropontius bandicola sp. nov., from Antipathes abies (L.) in the Moluccas and Antipathes cf. spinescens Gray in northwestern Madagascar, has rounded lateral margins on the female genital somite and the free segment of leg 5 is elongate with the ratio 2·69:1. Orecturus grandisetiger gen. nov., sp. nov., from Antipathes ericoides Pallas and Antipathes longibrachiata (van Pesch) in northwestern Madagascar, Antipathes reticulata Esper in the Moluccas, and Antipathes sp. at Bohol, Phillipines, has an unusually large seta on the third segment of the first antenna. Three lichomolgid poecilostomatoids are described from Antipathes sp. at Bohol in the Philippines. Visayasia lobura gen. nov., sp. nov., and Visayasia subterna gen. nov., sp. nov., are characterized by having the third segment of the endopod of leg 1 in both sexes armed with I, I, 4. Paramolgus delicatulus sp. nov., has a short caudal ramus and the female genital double somite is indented. The range of Paramolgus insectus (Humes, 1969) is extended from Madagascar and the Moluccas to the Philippines.
