Type material

Syntypes

INDONESIA • 1 spec.; Halmahera Sea ; 0°59.1′ S, 129°28.8′ E; depth 411 m; NATURALIS • 1 spec.; near Kei Is.; 5°26.6′ S, 132°32.5′ E; depth 397 m; NATURALIS .

Remarks

The figured syntype ( Fig. 32H , SL 28.7 mm) demonstrates all conchological characteristics of Leucosyrinx , including a subsutural anal sinus occupying the entire subsutural ramp. Therefore, the species is transferred to Leucosyrinx . It is most similar to L. breviplicata , differing in the more broadly-spaced spiral cords on the shell periphery.

Distribution

Indonesia to NW Australia, 300– 411 m.
