Type material

Holotype

WESTERN AUSTRALIA • off Port Hedland ; 17°58′ S, 118°25′ E; depth 376 m; WAM S14436 .

Remarks

The species was described based on two specimens. However, only the holotype, which is a dead-collected and heavily worn shell lacking the protoconch and upper teleoconch whorls, with a shell length of 35.3 mm, was illustrated. The shell morphology, including the shape and position of the subsutural anal sinus extending across the subsutural ramp, allows for confident placement in the genus Leucosyrinx . For differences from L. claviforma , see the Remarks section of that species.

Distribution

Western Australia, 376– 494 m.
