Goniodoridella savignyi Pruvot-Fol, 1933: 117 , 118, pl. 2, figs. 23-26; Baba, 1960: 81, pl. 8, figs. 1A-1F; Debelius and Kuiter, 2007: 28; Kil et al., 2020: 214, 215.

Material examined. 1 individual (MO00178869): Munamjin-ri , Jugwang-myeon , Goseong-gun, Gangwon-do, Korea, 38°18′04.04″N, 128°34′10.08″E, 06 May 2021 ; 1 individual ( NIBRIV0000882618 ): Munamjin-ri , Jugwang-myeon , Goseong-gun, Gangwon-do, Korea, 38° 18′04.04″N, 128°34′10.08″E, 16 July 2020 ; 1 individual ( NIBRIV0000882375 ): Geojin-ri , Geojin-eup , Goseong-gun, Gangwon-do, Korea, 38°27′09.01″N, 128°28′03.01″ E, 23 February 2019 .

Diagnosis. Body limaciform (length 5 mm, width 1.2 mm), ground color opaque, creamy white. Middorsal longitudinal crests of bright yellow specked-tubercles run from rhinophores to gill. Lateral papillae with yellow tip seven in number present on each side of marginal mantle edge. Two elongated, yellow tipped papillae in front of rhinophores. Rhinophores slender, long, cylindrical, tipped with yellow. Gills three, bipinnate, finger-shaped, tipped in yellow. Metapodium elongate, pointed, tipped in yellow.

GenBank accession number. OK143202.

Distribution. Korea, Australia, Japan, Philippines, Russia, Singapore, the Red Sea, South Africa.

Remarks. This species is widely distributed throughout the world from the tropical to subtropical seas, including Indo-Pacific waters. The color patterns of external body and the presence of middorsal longitudinal crests tipped with yellow examined from our specimens are distinct morphological features of this species. The occurrence of this species from Korean waters (Yellow Sea) was firstly reported in 2006 ( Koh, 2006), but this study provides morphological description and molecular data of DNA barcode sequences.
