Leucosyrinx undetermined

Leucosyrinx sp. 16 Figs 20B, 21G–H Material examined (sequenced) PHILIPPINES • 1 lv; Luzon I.; 15°37′ N, 121°59′ E; depth 1273–1333 m; AURORA 2007, stn CP2754; MNHN-IM-2009-13401. Description RADULA (Fig. 20B). Medium long, comprising about 30 rows of teeth, 11-12 nascent. Marginal teeth duplex, ~370 µm in length (4.6% AL without canal). Major limb narrow lanceolate in dorsal view, 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. DNA diagnosis (based on 1 (!) cox 1 sequence) ‘C’ in site 112, ‘T’ in site 205, ‘G’ in site 268, ‘G’ in site 511. Remarks The species is represented in our material by a single specimen (SL 25.7 mm). There is a certain resemblance to the not closely related L. exulans in shell shape and coloration. The differences are the following: significantly weaker spiral sculpture, light, nearly white canal, angulated shell base at transition to canal.
