Most of the shark and ray type material at the South China Sea Fisheries Research
Institute (SCSFRI) in Guangzhou, China was examined during a museum visit by the senior
author in 2009. The status of the shark and ray species described from the South China
Sea in the 1980s and deposited in this collection is discussed. Squalus acutirostris
is considered a junior synonym of Squalus mitsukurii from the western North Pacific.
Centrophorus ferrugineus is considered a junior synonym of Centrophorus squamosus.
Centroscymnus macrops is confirmed as a junior synonym of Centroscymnus coelolepis.
Scymnodon niger is confirmed as a junior synonym of Zameus squamulosus. Isistius labialis
is considered a synonym of Isistius brasiliensis. Halaelurus immaculatus is confirmed
as a valid species of the genus Bythaelurus. Urolophus marmoratus is considered a
junior synonym of the widespread Plesiobatis daviesi. Springeria nanhaiensis is a
questionable synonym of Sinobatis borneensis, following previous researchers. Springeria
stenosoma is considered as questionably valid but with further investigation into
generic placement required. The validity of species with SCSFRI type specimens not
examined in this study are also briefly discussed.
