Softrayed portion of fins translucent, with poorly defined dark blotches; soft-rayed portion of dorsal fin with four poorly defined dark blotches. No distinct large blotch on spinous portion of dorsal fin. Anal fin whitish with three or four dark bands obliquely across the fin. Caudal fin with three dark bands.
Remarks. Taxonomically useful characters of Parascorpaena aurita have at no time been described in detail. Accordingly, very few records of P. aurita exist in the literature, even in faunal checklists, although the species is common in shallow tropical and subtropical waters in the Indo-West Pacific (all specimens examined during this study were collected from less than 30 m depth). On the other hand, the species has often been mis-identified or reported as an unidentified species, examples including Weber & de Beaufort’s (1962) description of P. p i c t a from the Indo-West Pacific, in which the meristics indicate the likelihood of P. aurita, P. m o s s a m b i c a and P. p i c t a having been included. A description and figure (as Parascorpaena sp.) from south of the Lesser Sunda Islands by Gloerfelt-Tarp & Kailola (1984: 112–113) appears to be P. aurita because of having occipital pit and fewer than 40 scale rows in longitudinal series. Manilo & Bogorodsky’s (2003) P. p i c t a from the Arabian Sea is undoubtedly P. aurita because of the distributional range given (see below).
In East Asian waters, P. aurita has rarely been reported (exception: Jones et al., 1972), although several records of P. p i c t a exist. Jones et al. (1972) listed P. aurita (UTIO–F. 96, 86 mm SL) from southern Taiwan (Hai-k’ou to O-luan-pi), stating that listed specimens had been deposited in the museum of the Institute of Oceanography, National Taiwan University, Taipei. However, because no fish specimens are presently held by the latter (T. Miki, pers. comm.), we could not confirm Jones et al.’s identification.
Although Chen (1981) reported P. p i c t a on the basis of three specimens from Heng-chun and Tai-tung in his taxonomic review of scorpionfishes in Taiwan, examination of one (NTUM 3858) of the three specimens (remaining two specimens not available to this study) and all specimens of Parascorpaena deposited at ASIZP and NTUM (see Material examined) showed them to be P. aurita. A photograph identified as P. p i c t a by Shao & Chen (1993: pl. 57, fig. 1) is also likely to be P. aurita. In addition, our examinations of scorpionfish specimens deposited at Japanese museums and specimens newly collected from the Ryukyu Islands revealed that P. a u r i t a is relatively common in Taiwan and the Ryukyu Islands. Such specimens represent the first reliable records of the species from East Asia (seven specimens from Taiwan and 49 specimens from Japan). A single specimen (BSKU 96650, 116.1 mm SL) from Yakushima Island (30°27’22”N, 130°29’47”E) represents the northernmost record of the species.
Incidentally, P. p i c t a figured by Shen (1984: pl. 30, fig. 264-14) was re-identified here as Scorpaena miostoma Günther, 1877. In addition, Chen’s (2003: fig. 210) report of P. p i c t a from Penghu now known to have been Scorpaena pepo Motomura et al., 2007. In fact, the present study showed that the distributional range of P. p i c t a is restricted to Southeast Asia and Australia, the species not occurring in East Asian waters, whereas P. aurita is widely distributed in the Indo-West Pacific, where it ranges from the east coast of Africa (Eschmeyer, 1986) and the Red Sea to southern Japan and Australia (Fig. 3).
Yearsley et al. (2006) reported the English name for P. aurita as “Golden Scorpionfish”, although that name was preoccupied for P. mossambica by Eschmeyer (1986). However, in recent year, “ Mozambique Scorpionfish” has been used for P. mossambica by many authors, including Randall et al. (1997), Poss (1999), Randall (2005), and Yearsley et al. (2006). Thus, we recognize “Golden Scorpionfish” and “ Mozambique Scorpionfish” as English names for P. aurita and P. p i c t a, respectively. Chiburu-nettaifusakasago is herein proposed as the new standard Japanese name for Japanese specimens of P. aurita.
