Type material

Holotype

NEW ZEALAND • 18 miles N, 30° E of Poor Knights Is. ; depth 256–267 fathoms (= 468–488 m); 20 Nov. 1962; MNZ, M.016273.

Remarks

The species was originally described based on two specimens, and no new specimens have been reported in the literature since its original description. In 1969, Powell transferred the species to the genus Leucosyrinx . However, the shell is characterized by the presence of a subsutural row of weak but distinct nodules – a feature never found in Leucosyrinx , but present in Sibogasyrinx and Comispira . In its slender shell with relatively weak uniform spiral sculpture the species is more similar to Sibogasyrinx . Therefore, we currently attribute the species, with some reservation, to Sibogasyrinx ; this needs confirmation through examination of the radula or molecular data.
