Remarks

Oxypleurodon auritum was described from the east coast of Luzon, the Philippines ( Rathbun, 1916), and has also been reported from Tosa Bay, Japan ( Takeda & Nagai 1979; Lee et al. 2015). Richer de Forges & Ng (2009b) referred specimens from the Bohol Sea, with a similar “mushroom-shaped” cardiac plate to a new species, O. boholense Richer de Forges & Ng, 2009 . Two other species with similar cardiac plates, O. barazeri Richer de Forges & Ng, 2009b , from the Solomon Islands and O. christiani Richer de Forges & Corbari, 2012 from Papua New Guinea, were recently described ( Richer de Forges & Ng 2009b; Richer de Forges & Corbari 2012).

The present specimens from the SCS are clearly conspecific with O. auritum as presently defined. The previous record of O. auritum from the SCS by Lee et al. (2015) was based on one specimen from the NANHAI 2014 expedition; the recent surveys collected more material. The live colours of this species were documented by Richer de Forges & Ng (2009b) and Lee et al. (2015).

Distribution

This species was recorded from the Philippines ( Rathbun 1916), Japan ( Takeda & Nagai 1979) and South China Sea ( Lee et al. 2015).
