Phascolosoma glabrum glabrum Cutler, 1994: 177 (for complete synonymy).

Material examined. Three specimens (NMNS-5928-019), Nanwun (21°57.30' N, 120°46.00' E), Pingtung County, intertidal reefs, coll. H.-T. Hung, 21 August 1988; one specimen (NMNS-5928-020), Sunsheintai (23°06.899' N, 121°24.012' E), Taitung County, intertidal reefs, coll. P.-W. Hsueh, 14 October 2007.

Remarks. Cutler and Cutler (1990) reviewed the genus Phascolosoma and suggested that Phascolosoma glabrum can be separated into two subspecies, P. glabrum glabrum sensu stricto and P. glabrum multiannulatum (Wesenberg-Lund) . Hooks in the present specimens agree with the descriptions of those in P. glabrum glabrum by Cutler (1994: 170, fig. 49B; present study, Fig 3 D). Most previous records of this species were from Indo-West Pacific islands (from Diego Garcia in Indian Ocean to Funafuti in South Pacific Ocean) in the Southern Hemisphere. Eniwetok in the Marshall Islands is the only known locality in the Northern Hemisphere (Cutler 1994). The present records add two new localities in the Northern Hemisphere. These two new localities mark its northernmost range.
