Remarks

This molecularly distinct species is represented in our material by a single specimen (SL 28.2 mm) and, due to the unknown intraspecific variability, we abstain from the formal description of a new species. It shows some resemblance to Leucosyrinx sp. 18, differing in a slightly broader shell with a higher spire. It is very similar to Leucosyrinx sp. 14 from the Coral Sea, differing in its larger size. Both species are not closely related to Leucosyrinx sp. 1 .
