ミナミヒメコダイ（ハタ科）の学名はChelidoperca santosi Williams and Carpenter, 2015

抄録

Previous Japanese records of Chelidoperca margaritifera Weber, 1913 (Perciformes: Serranidae) were reviewed, and all available Japanese specimens previously reported as that species found to be either C. santosi Williams and Carpenter, 2015 or C. tosaensis Matsunuma, Yamakawa and Williams, 2017. No evidence was found of C. margaritifera occurring in Japanese waters, the species instead being known solely from the holotype, collected off New Guinea. Chelidoperca santosi is characterized by three scale rows between the lateral line and middle of the spinous dorsal-fin base; two pairs of dark spots on the snout; a pair of dark spots on the lower jaw tip; the interorbital scales just reaching or extending slightly beyond mid-orbit but not reaching level with the posterior nasal pores; scales on the mandibular ventral surface extending anteriorly onto the dentary; and enlarged canine-like teeth on both jaws, thereby being distinguished from all Japanese congeners [C. hirundinacea (Valenciennes in Cuvier and Valenciennes, 1831), C. pleurospilus (Günther, 1880) and C. tosaensis]. The standard Japanese name “Minamihimekodai” should be applied to C. santosi.
