Figs 27I–J , 29D–E

Material examined (sequenced)

SOLOMON ISLANDS • 1 lv; E of Malaita; 8°43′ N, 161°00′ E; depth 314–410 m; SALOMONBOA 3, stn CP2798; MNHN-IM-2009-6036 .

Description

RADULA ( Fig. 29D–E ). Comprising about 30 rows of teeth, 8 nascent. Marginal teeth duplex, ~255 µm in length (5.8% AL without canal). Major limb narrow lanceolate in dorsal view, strongly curved. Accessory limb about half of tooth width, ~0.75 of total tooth length, inserted into distinct deep socket on dorsal side of major limb.

Remarks

This molecularly distinct species is represented in our material by a single specimen. It is conchologically nearly identical to Leucosyrinx sp. 7 , although significantly smaller (SL 15.2 mm).
