Leucosyrinx undefined-7

Leucosyrinx sp. 7 Figs 2, 27A–B 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-2013-19933. Description RADULA (Fig. 2). Typical of the genus. Marginal teeth ~370 µm in length (5.2% AL without canal). DNA diagnosis (based on 1 (!) cox 1 sequence) ‘G’ in site 52, ‘G’ in site 265, ‘G’ in site 569. Remarks This molecularly distinct species is represented by a single specimen in our material. Conchologically it is indistinguishable from some specimens of L. breviplicata and Leucosyrinx sp. 26. From the latter it also differs in the presence of a slightly darker spiral band on the shoulder. It co-occurs with Leucosyrinx sp. 26 in the Solomon Sea (collected at neighbouring stations with the difference of only two minutes of longitude). Leucosyrinx sp. 7 is sister species to Leucosyrinx sp. 26, but both species are separated in all the ASAP partitions.
