Abstract
The present study describes a new species of Pyrgoma Leach, 1817, a coral associated barnacle attached to Tubastrea, from the south of New Caledonia. Pyrgoma spurtruncata sp. nov. is morphologically close to P. cancellatum Leach, 1818, P. japonica Weltner, 1897 and P. kuri Hoek, 1913 in the absence of extended tergal muscle crests. Pyrgoma cancellatum and P. kuri have a shallow, fully open, medial furrow of the tergal spur, whereas in P. spurtruncata sp. nov. the medial furrow is deeper and closed. Pyrgoma spurtruncata sp. nov. differs from P. japonica Weltner, 1897 in the width of the tergal spur and the length of the rostral tooth of the scutum. Phylogenetic analyses based on two mitochondrial markers, 12S rDNA and COI, confirm a unique, distinct clade of P. spurtruncata sp. nov. among the current available molecular information regarding Pyrgoma species.

The specimens studied herein were collected during the BIOCAL (1985), SMIB3 (1987) and SMIB4 (1989) cruises organized by the Muséum National d'Histoire Naturelle and the Institut de Recherche pour le Développement within the framework of the Tropical Deep Sea Benthos program (https://expeditions.mnhn.fr/program/tropicaldeep-seabenthos). The authors would like to thank the crew of the vessels for helpful assistance during sampling at sea, and Wei-Peng Hsieh for help with SEM preparations. Thanks to Dr Yu-Rong Cheng, National Kaoshiung University of Science and Technology, Taiwan for identifying the host corals. The work of YA was supported by the Israel Science Foundation grant 308/14. Part of the material used in this study was collected during a visit by YA to the collections of the Museum National d'Histoire Naturelle, Paris (1MNHN) supported by the SYNTHESYS Project (http:// www.synthesys.info), which is financed by the European Community Research Infrastructure Action under the Integrating Activities Programmes (FR-TAF-3382).
