A new genus of Lichomolgidae (Copepoda: Poecilostomatoida) associated with a phoronid in Hong Kong Geoffrey A. Boxshall Department of Zoology, British Museum (Natural History), Cromwell Road, London SW7 5BD Arthur G. Humes Boston University Marine Program, c/o Marine Biological Laboratory, Woods Hole, Massachusetts 02543, U.S.A. Introduction Copepods are rarely reported as parasites or associates of the lophophorate phyla Bryozoa, Brachiopoda and Phoronida. Two new harpacticoids, Tegastes knoepffleri and Peltobradya bryozoophila, were described by Medioni & Soyer (1967) as associates of the bryozoans Schizobrachiella sanguined (Norman) and Schizomavella linearis (Hassall) respectively, at Banyuls-sur-Mer in southern France. Recently Humes & Boxshall (1988) described a new genus of the family Myicolidae which occurs on the intertidal brachiopod Lingula anatina Lamarck col-lected at Starfish Bay, New Territories, Hong Kong. This is the first known copepod associate of a brachiopod. Examination of other invertebrates collected at the same time in Starfish Bay has revealed a copepod associated with a phoronid, Phoronis australis Haswell, which is itself an associate of the burrowing anemone Cerianthusfiliformis Carlgren. The phoronid lives embedded in the mucilaginous tube of the Cerianthus (Morton & Morton, 1983). Three copepods were found in the lophophore of the phoronid and are described below as a new genus of the family Lichomolgidae. Material and Methods The phoronid was collected by a diver at a depth of 3 to 5 m in Hoi Sing Wan (Starfish Bay). The phoronid was placed in a plastic bag, transported to the laboratory and examined live. The copepods were picked off and fixed in 70% ethanol. All figures were drawn with the aid of a camera lucida. Descriptions Genus PHORONICOLA gen. nov. DIAGNOSIS. Body cyclopiform. Urosome in 9 4-segmented, in $ 5-segmented. Caudal ramus with 6 setae.
