Material examined (sequenced)

NEW CALEDONIA • 1 lv; 22°23′ N, 167°26′ E; depth 810–960 m; TERRASSES, stn DW3085; MNHN-IM-2009-29312 .

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

‘G’ in site 31, ‘C’ in site 451, ‘A’ in site 538, ‘T’ in site 583.

Remarks

This separate species is represented in our material by a single broken specimen (SL 18.0 mm) and thus we abstain from its formal description. Conchologically it is most similar, if morphologically distinguishable, to Leucosyrinx sp. 24, and both are sister species in the phylogenetic tree: they may actually correspond to a single species.

Distribution

New Caledonia, 810– 960 m.
