News and Comments

The original description of platycephalid Rogadius asper (Cuvier in Cuvier and Valenciennes 1829) was based on a single specimen collected from Japan. The species has been recently reported from southern Japan, Korea, East China Sea, Taiwan, Vietnam (Nha Trang) and northern Australia (e.g., Shao and Chen 1987; Lee and Joo 1998; Imamura et al. 2006; Paxton et al. 2006). The widespread Rogadius pristiger (Cuvier in Cuvier and Valenciennes 1829), occurring from Taiwan to northern Australia and Madagascar, including the Philippines, Andaman Sea, Gulf of Oman and Red Sea (e.g., Knapp 1999; Vilasri et al. 2015; Kimura et al. 2017), has been misidentified as R. asper by many authors, because of a distinctive taxonomic character, a strong antrorse preopercular spine that is present in both. Characters useful for separating them had not been well known prior to the study by Imamura et al. (2006). Although a third species, the recently described Rogadius fehlmanni Knapp 2012from Somalia, also...



I am deeply indebted to G Dally and M Hammer (NTM), M Gomon and D Bray (NMV), A Graham (CSIRO), J Johnson (QM), M McGrouther and A Hay (AMS), and G Moore and M Allen (WAM) for making specimens available when I visited their museums and institution. I also offer my sincere thanks to M Gomon (NMV) for giving valuable comments on the draft manuscript. This study was mostly supported by JSPS KAKENHI Grant Number 2544019603 and partly by “Japan Society for the Promotion of Science (JSPS) Asian Core Program—Establishment of research and education network on coastal marine science in Southeast Asia” funded to the author.
