簡単な記述 形態学 | 形態計測学

背面の脊椎 (合計): 0; 背鰭 (合計): 8-9; 肛門の骨 0; 臀鰭: 19 - 20; 脊つい: 38 - 40. It is characterized by the combination of the absence of a supraorbital bone, and the presence of a deep-lying midlateral stripe extending along the body onto the caudal peduncle, a band of chromatophores above the anal fin, and a small pair of inner row symphyseal teeth on the dentary (Ref. 59215). It has also an elevated vertebral count of 38 to 40, and 4 to 6 outer row premaxillary teeth are present with a majority of the specimens, with only 4 outer row teeth implanted in an alternating pattern with respect to the anterior inner row premaxillary teeth (Ref. 59215). Number of dorsal fin rays is ii,6-7 and anal fin rays is iii,16-17 (Ref. 59215). In life a broad, blue-green iridescent midlateral band covers the lateral flanks and tail from behind the opercle to the base of the caudal fin; this band overlies and obscures the deep lying midlateral stripe evident in preserved specimens; above and below the midlateral band the body is silvery white (Ref. 59215). Numerous melanophores are present on the head and opercle, and scattered over the body with a concentration around lateral scale margins (Ref. 59215). Dorsal fin and pectoral fins are dusky gray; adipose fin is pale grey with a dark distal margin; caudal fin is dusky gray and medially each fin fork is deep crimson red; anterior and distal margins of anal fin are white, while the remainder of the fin is jet black; pelvic fins are white (Ref. 59215).
