Remarks

This molecularly distinct species is represented in our material by a single partially broken specimen (SL 38.7 mm), therefore, we abstain from describing a new species. It resembles L. herosae sp. nov., differing in a more convex last whorl, which constricts faster towards the canal, as well as in more distinct and broader spaced thin spiral cords, and more pronounced and more orthocline axial folds. The shape of the shell base resembles L. luzonica , differing in having a taller spire and broader spaced spiral cords. None of them are sister species of Leucosyrinx sp. 17 in the phylogenetic tree.
