Material examined (sequenced)

VANUATU • 1 lv; SE Malékula I.; 16°22′ S, 167°50′ E; depth 637–644 m; SANTO 2006, stn AT130; MNHN-IM-2007-42637 .

DNA diagnosis (based on 1 (!) cox 1 sequence)

‘G’ in site 253, ‘T’ in site 322, ‘A’ in site 353, ‘C’ in site 553.

Remarks

The species is represented by a single rather worn shell, which is rather similar to Leucosyrinx claviforma . The slight differences are more yellowish color, less distinct spiral cords and shoulder axial folds. However, the only available specimen is heavily corroded and the differences in prominence of spirals may be attributed to this. In the phylogenetic tree these species are not sister.
