Cuvier in Lesson, 1828 )—Rough-toothed Dolphin Delphinus bredanensis G. Cuvier in Lesson, 1828 p.206 ; Type locality- Coast of France . D. rostratus Desmarest, 1817 p.160 (not valid by Miller, 1924 see p.508). Steno rostratus Gray, 1846 p.43 ; Type locality- North Sea; Miller, 1924 p.508 ; Kuroda, 1938 p.17 . S. bredanensis : Kim et al. , 2000 p.106 ; Kim, 2004 p.249 . Range: The range of S. bredanensis reaches the South Sea of Korea ( Fig. 98 ). A few vagrant individuals have stranded on Jeju Island and Busan ( Kim 2004 ). Remarks: Kuroda (1938) named this species in Korea as S. rostratus , but the latter was synonymized into S. bredanensis ( Watkins et al. 1987 ) . A controversy arose over whether Steno should be grouped with Orcaella or Sotalia ( Caballero et al . 2008 , McGowen et al . 2009 , Steeman et al . 2009 ). Recent DNA investigations failed to confirm all of the revisions suggested by LeDuc et al . (1999) and did not produce consistent estimates of phylogenetic relationships within the family ( LeDuc et al . 1999 ; Caballero et al . 2008 ). Traditionally, based on morphological similarity, the Genus Steno was placed in the Subfamily Stenoninae with the Genera Sousa , and Sotalia ( Perrin 1989 , Vilstrup et al . 2011 ). Steno bredanensis is currently considered a monotypic taxon.
