Type material

Syntypes

TANZANIA • 3 specs; Zanzibar Channel ; 5°27′ S, 39°19′ E; depth 463 m; ZMB Mol 109384 .

Remarks

The species is known from three dead-collected and immature shells (maximal SL 7.8 mm). It is characterized by strong and very closely spaced spiral cords below shoulder that was not found in other species of Leucosyrinx , although somewhat similar but broader cords are also found in L. nodulocordata sp. nov. In the absence of any data on anatomy, we retain it in Leucosyrinx with strong doubts.

Distribution

Type locality.
