Fig. 27G–H

Material examined (sequenced)

SOLOMON SEA • 1 lv; SE of Tuam Is ; 6°04′ S, 148°12′ E; depth 500–575 m; PAPUA NIUGINI, stn CP4009; MNHN-IM-2013-19929 (sympatric with sp. 6)

DNA diagnosis (based on 1 (!) cox 1 sequence)

‘C’ in site 145, ‘C’ in site 151, ‘C’ in site 367, ‘G’ in site 403.

Remarks

This molecularly distinct species is represented in our material by a single specimen. It is conchologically nearly identical and sympatric to Leucosyrinx sp. 7 . Nevertheless in Leucosyrinx sp. 4 the spiral cords are less distinct than in Leucosyrinx sp. 7 , and the two species are phylogenetically not closely related.
