Leucosyrinx lancea Y.-C. Lee, 2001: 8 , fig. 2a–d.

Type material

Holotype

TAIWAN • off Pratas I.; depth 430–610 m; dredged by shrimp trawlers; NMNS-3704001 .

Material examined (sequenced)

PHILIPPINES • 1 lv; Luzon I.; 15°53′ N, 121°54′ E; depth 518–538 m; AURORA 2007, stn CP2750; MNHN-IM-2009-13465 .

Remarks

The species is characterized by a subsutural row of rounded knobs. This is not found in any species of Leucosyrinx , but is, conversely, present in all species of Sibogasyrinx and Comispira . Moreover, a very similar specimen (MNHN-IM-2009-13465 – Fig. 35E ), collected off Luzon, Philippines, at similar depths (518–538 m) was recently sequenced and a partial cox 1 sequence confidently places it in Sibogasyrinx . Therefore, we transfer it to Sibogasyrinx .

Distribution

Taiwan to Philippines, 430– 518 m.
