2005 Solariella tobaruensis Noda, 1988 ; Hasegawa 2005: fig. 4E. 2017 Solariella tabaruensis [sic!] Noda; Sasaki 2017: 754, pl. 26: 12.

Material.— One specimen from the Pleistocene of Antipolo Point : NMNS PM 28443 (W = 4.5 mm, H = 4.5 mm) .

Remarks.—This specimen is identical to an extant shell identified as Solariella tobaruensis Noda, 1988 , collected in c. 520 m depth off Omami-oshima island (Ryukyu Islands, southern Japan) and illustrated in Hasegawa (2005) and Sasaki (2017). However, the name Solariella tobaruensis is based on a Plio-Pleistocene fossil from Okinawa, Japan ( Noda 1988: 33, pl. 5: 5, 6), which has a more distinct shoul- der and a deeper suture than both the extant specimen just mentioned and the Philippine specimen reported here.
