Coloration when fresh — Upper part of head blackish-red, lower part whitish with pinkish-orange mottling. Dorsal midline of head with discontinuous reddish-orange stripe from upper jaw to origin of dorsal fin. Body dark red, darkest dorsally. Dorsal and anal fins dark red, lighter distally. A single faint whitish-grey mid-lateral stripe on both dorsal and anal fins. Outer margin of soft rays of both fins white. Pectoral fin translucent, red with blackish-red base. Pelvic fin translucent, red with dark red base. Caudal fin dark to lighter red, with faint whitish-grey mid-caudal stripe and white outer margin. Coloration of preserved specimen — Upper part of head blackish-brown, lower part pale. Mid-dorsal stripe pale. Body dark brown. Dorsal, anal and caudal fins blackishbrown with pale distal margins. Outer margin of caudal fin blackish-brown. Pectoral and pelvic fins whitish with blackish-brown base.	en	Yoshida, Tomohiro, Kuriiwa, Kaoru, Motomura, Hiroyuki (2018): First Confirmed Japanese Record of Suttonia lineata (Perciformes: Serranidae) from Iwo Island, Volcano Islands.

03B287BC554B2136248C71DDFA8CF803.taxon	distribution	Distribution and habitat. Suttonia lineata has been recorded from Christmas Island and the Cocos Keeling Islands in the eastern Indian Ocean, and the following Pacific Ocean localities: Oahu (Hawaiian Islands), Tahiti and Moorea (Society Islands), Tabaueran (Line Islands), Tonga (Tonga), Viti Levu, Viwa Island, Great Astrolabe Reef (Fiji), Emae Island (Vanuatu), New Caledonia, Tautsina Island (Solomon Islands), Guam (Mariana Islands), Lizard Island and the Coral Sea (Australia), Moluccas and Sulawesi (Indonesia), Siquijor Island (Philippines) and Iwo Island (Volcano Islands, Japan) (Allen and Smith-Vaniz 1994; Randall and Baldwin 1997; Allen 2000; Randall et al. 2003; this study). Collection data for a range of specimens indicate a depth range for the species of 6 – 30.5 m (Randall and Baldwin 1997). The present specimen was collected under large overhanging rocks at 17 m depth.	en	Yoshida, Tomohiro, Kuriiwa, Kaoru, Motomura, Hiroyuki (2018): First Confirmed Japanese Record of Suttonia lineata (Perciformes: Serranidae) from Iwo Island, Volcano Islands.

03B287BC554B2136248C71DDFA8CF803.taxon	discussion	Remarks. The specimen from Iwo Island was identified as a species of Suttonia, having the following combination of characters: dorsal-fin rays VII, 22 – 25; anal-fin rays III, 18 – 22; pectoral-fin rays 14 – 17; single lateral line with 26 – 40 pored scales; a mid-dorsal stripe on head; and absence of cteni on scale posterior edges (Randall and Baldwin 1997; Endo and Kenmotsu 2013; Yoshida and Motomura 2014; this study). It was subsequently confirmed as S. lineata, having 40 pored scales on the lateral line, the inner pectoralfin base with scales, and a faint dark blotch on the opercle (Randall and Baldwin 1997; Endo and Kenmotsu 2013; this study). Suttonia lineata is distinguished from S. coccinea and S. suttoni by the large number of pored scales on the lateral line (37 – 41 in S. lineata vs. 26 and 27 – 35, respectively, in the latter two species) (Randall and Baldwin 1997; Endo and Kenmotsu 2013; this study). Endo and Kenmotsu (2013: table 1) provided meristics and morphometrics of 12 specimens (66 – 80 mm SL) of S. lineata, although they listed only 11 specimens (23 – 80 mm SL) under “ comparative material ”. Most of the meristic and morphometric values for the Iwo Island specimen are within the ranges for the non-type specimens of S. lineata given by Endo and Kenmotsu (2013) (Tables 1 – 2). However, the former specimen differed slightly in some morphometric measurements, as follows: anal-fin base length 30.9 % SL (vs. 31.0 – 33.2 % SL in the latter); pectoral-fin length 29.1 % SL (vs. 24.8 – 27.8 %); caudal-peduncle depth 10.6 % SL (vs. 10.9 – 12.7 %); and interorbital width 7.4 % HL (vs. 7.6 – 9.1 %) (Table 2). These small differences were regarded here as intraspecific variations. Although Allen and Erdmann (2012) included Japan within the distributional range of S. lineata, the record was unsupported, there being neither underwater photographs nor voucher specimens of the species from Japan (G. Allen, pers. comm.). In addition, the northernmost record of the species to date, based on voucher specimens, is the Hawaiian Islands (Randall and Baldwin 1997). Therefore, the Iwo Island specimen represents the first reliable record from Japan and the northernmost record for the species. A new standard Japanese name, Kazan-kurenai-togemegisu, is proposed for S. lineata, “ kazan ” being Japanese for “ volcano ” and referring to the collection locality (Volcano Islands), as well as the reddish body coloration of the species, reminiscent of magma. “ Kurenai-togemegisu ” is the common Japanese name for the genus Suttonia.	en	Yoshida, Tomohiro, Kuriiwa, Kaoru, Motomura, Hiroyuki (2018): First Confirmed Japanese Record of Suttonia lineata (Perciformes: Serranidae) from Iwo Island, Volcano Islands.
