Leucosyrinx sp. 2

Figs 19N , 20A

Material examined (sequenced)

SOLOMON ISLANDS • 1 lv; Santa Isabel I.; 8°49′ N, 159°43′ E; depth 765–773 m; SALOMON 2, stn CP2179; MNHN-IM-2009-16783 .

Description

RADULA ( Fig. 20A ). Comprising about 35 rows of teeth, 12 nascent. Marginal teeth duplex, ~200 µm in length (2.7% AL without canal). Morphology of teeth very similar to that of Leucosyrinx sp. 1 .

DNA diagnosis (based on 1 (!) c ox1 sequence)

‘C’ in site 163, ‘G’ in site 517, ‘T’ in site 622.

Remarks

This species is represented in our material by a single specimen. It is conchologically very similar to Leucosyrinx sp. 1 . Since both species are represented by singletons and intraspecific variability is not known, we can not draw morphological differences between them.
