Leucosyrinx sp. 22 Figs 10G, 13G–I Material examined (sequenced) CORAL SEA • 1 lv; S Lansdowne Bank; 21°02′ S, 161°11′ E; depth 810–840 m; KANADEEP, stn CP5054; MNHN-IM-2013-48155 • 1 lv; S Lansdowne Bank; 21°08′ S, 161°13′ E; depth 900–950 m; KANADEEP, stn CP5055; MNHN-IM-2013-48160. SOUTHERN NEW CALEDONIA • 1 lv; 22°23′ N, 167°22′ E; depth 756–769 m; EXBODI, stn CP3842; MNHN-IM-2009-29110. Description RADULA (Fig. 10G). Short, comprises around 30 rows of teeth, 7 nascent. Marginal teeth duplex, ~315µm in length (5.3% AL without canal). Major limb narrow lanceolate in dorsal view, curved. Accessory limb constitutes slightly less than half of tooth width, ~0.75 of total tooth length, inserted into distinct deep socket on dorsal side of major limb. DNA diagnosis (based on 3 cox 1 sequences) ‘G’ in site 199, ‘T’ in site 316, ‘C’ in site 406, ‘C’ in site 658. Remarks This medium-sized species is represented in our material by three specimens, all incomplete, with broken aperture lips. Therefore, we abstain from its formal description as a new species. Conchologically it is very similar if distinguishable from L. gaelae sp. nov., differing in a relatively longer siphonal canal; both species are phylogenetically not closely related. It is so far found in the Coral Sea and off southern New Caledonia, while L. gaelae is recorded off New Britain, Papua New Guinea at similar depths. Distribution New Caledonia, Coral Sea, 756– 900 m.
