Two new species of ancyrocephalid monogeneans from Lethrinus rubrioperculatus Sato (Perciformes: Lethrinidae) off New Caledonia, with the proposal of Lethrinitrema n. g.

Lethrinitrema gibbus n. g., n. sp. and L. dossenus n. sp. are described from the fish Lethrinus rubrioperculatus Sato collected off New Caledonia, South Pacific. Members of Lethrinitrema n. g. (Ancyrocephalidae) are characterised by having two pyriform haptoral reservoirs and ventral anchors with lateral grooves. The elongate tubular distal end of each reservoir bifurcates, draining into a superficial lateral groove on each side of the ventral anchors. The haptoral reservoirs are postulated to store secretory products which assist in attachment to the host. Lethrinitrema spp. also possess tandem gonads, a male copulatory organ without an accessory piece or with thinly sclerotised accessory piece, and a dextrolateral, non-sclerotised vaginal bulb. The two new species have small, poorly demarcated haptors with small haptoral armament and a crown-like piece on the tip of the inner root of the ventral anchors. They differ from each other in the shape and size of the ventral bar and male copulatory organ (40–45 μm in length in L. gibbusvs 24–30 μm in L. dossenus). Three other species, previously included in Haliotrema Johnston & Tiegs, 1922, are transferred to Lethrinitrema, i.e. L. chrysostomi (Young, 1968) n. comb., L. fleti (Young, 1968) n. comb. (both briefly redescribed from paratypes) and L. lethrini (Yamaguti, 1937) n. comb. All species of Lethrinitrema parasitise Lethrinus spp. (Lethrinidae), and there is evidence for the existence of further Lethrinitrema spp. on Lethrinus spp. in the Indo-Pacific region.

Kent Carpenter (Norfolk, Virginia, USA) helped in identifying Lethrinus spp. on photographs. Julie Mounier, a volunteer technician, and Charles Beaufrère, Audrey Guérin, Anaïs Guillou, Amandine Marie, Chloé Journo, Violette Justine, Eric Bureau, Maya Robert, Damien Hinsinger, Aude Sigura and Guilhem Rascalou, all students, participated in the fishing operations and parasitological survey. Angelo di Matteo (IRD) provided technical help and Liew K.S. assisted with the fishing and with the collection and preparation of specimens for this study. Gérard Mou Tham (IRD) spear-fished certain specimens. We would like to thank the French Embassy in Malaysia for funding the visit of the first author and Liew K.S. to New Caledonia.
