Type material

Syntypes

TANZANIA • 1 spec.; Zanzibar Channel; 5°27′ S, 39°18′ E; depth 463 m; Valdivia, stn 245; ZMB Mol 109383 • 25 specs; Dar Es Salaam; Valdivia, stn 242; ZMB Mol 109383 .

Remarks

The species is known only from numerous empty juvenile shells (SL up to 5.8 mm) from two stations off Tanzania. The spiral sculpture on the last whorl is dominated by several strong cords below the shoulder crossing axial folds extending in some specimens to the shell base and thus isolating two or sometimes three rows of strong nodules (more pronounced than in the figured herein syntype). This type of sculpture is not found in any species of Leucosyrinx, and we exclude the species from the genus. Current taxonomic position is unknown.

Distribution

East Africa, Tanzania, 463 m.
