Leucosyrinx eurina, comb. nov.

Leucosyrinx eurina (E.A. Smith, 1899) comb. nov. Fig. 32E Pleurotoma (Surcula) eurina E.A. Smith, 1899: 239. Pleurotoma (Surcula) eurina – Annandale & Stewart 1909: pl. 9 figs 4, 4a. Comitas eurina – Powell 1969: 268 (23-280), pl. 217 figs 4–5. — Tan & Islami 2021: 325, fig. 9b. Type material Holotype INDIAN OCEAN • Travancore coast; depth 430 ftm (= 790 m); Investigator, stn 232; ZSI, M 647/1. Paratype INDIAN OCEAN • 1 spec.; same data as for holotype; NHMUK 1904.6.15.139. Remarks The shell of L. eurina is unusual for the genus due to the distinct subsutural spiral fold, a feature somewhat similar to what is observed in our sequenced specimen of L. thisbe (Fig. 17C–E). On the other hand, the anal sinus is subsutural and occupies entire subsutural ramp, thus suggesting the transfer of the species from Comitas to Leucosyrinx. Distribution From off southern India to Indonesia, 790– 940 m.
