Material examined (sequenced)

SOUTHERN NEW CALEDONIA • 1 lv; Pass de la Sarcelle , 22°27′ N, 167°25′ E; depth 470–570 m; TERRASSES, stn DW3083; MNHN-IM-2009-29323 GoogleMaps .

Description

RADULA ( Fig. 10H View Fig ). Marginal teeth duplex, ~240 µm in length (4.6% AL without canal). Major limb medium broad, lanceolate in dorsal view, curved. Accessory limb constitutes slightly over 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 1 (!) cox 1 sequence)

‘C’ in site 286, ‘C’ in site 428, ‘C’ in site 436.

Remarks

This medium-sized (SL 20.1 mm) species is represented by a single specimen. Since the variability is unknown, we abstain from a formal description of the new species.

It is similar to Leucosyrinx sp. 22 ( Fig. 13G–I View Fig ), also from southern New Caledonia, although the phylogenetic tree demonstrates that they are not closely related. Conchologically it differs in a much better developed spiral sculpture of irregularly and broadly-spaced spiral cords.

Distribution

New Caledonia, 470– 570 m.
