Leucosyrinx palawanica Kantor & Fedosov & Puillandre 2025, comb. nov.

Leucosyrinx palawanica (Powell, 1969) comb. nov. Fig. 33A Comitas aequatorialis palawanica Powell, 1969: 282 (23-294), pl. 225 figs 5–6. Type material Holotype PHILIPPINES • Palawan Passage; 10°46′40″ N, 118°29′ E; depth 515 ftm (= 941 m); Albatross, stn 5350; USNM 237910. Remarks The species is known from a single holotype with SL of 43.5 mm. The shell sculpture pattern and the shape of the subsutural anal sinus fit well within the variability observed in species of Leucosyrinx as defined here. Therefore, we transfer the species to Leucosyrinx. Originally, it was described as a subspecies of L. aequatorialis Thiele, 1925, but differs markedly in size (43.5 mm vs 13 mm). Additionally, in L. aequatorialis, the last whorl lacks axial ribs and a shoulder carina, while the carina is well-developed in L. palawanica. Therefore, we consider it a separate species. Distribution Type locality.
