----------------------------
Description
Dorsal spines (total): 7-8; Dorsal soft rays (total): 9, all rays branched, the last to base; Anal spines: 2; Anal soft rays: 8. Pectoral fin rays: 13, the upper and lower two unbranched; Pelvic fin rays: I, 5, all rays branched; Principal caudal fin rays: 17, the upper and lower rays unbranched; Upper and lower procurrent caudal rays: 7, the most posterior (and occasionally the one preceding it) segmented; Lateral line scales: 24 (rarely: 25); Predorsal scales: 4; Gill rakers: 3-5 + 11-14; Branchiostegal rays: 7; Predorsal bones: 3; Vertebrae: 10+14. Preopercular margin serrate; Preopercular ridge smooth; Body depth: 2.9-3.6 in SL; Mouth large, the maxilla reaching or nearly reaching a vertical at rear edge of pupil, the upper jaw length: 2.1 in head; Mouth oblique, the gape forming an angle of about 30° to horizontal axis of head and body. Max. length: 4.0 cm SL. Depth range: 3 - 60 m.
Color
Translucent pale pinkish gray, becoming silvery on lower half of head and silvery white ventrally on thorax and abdomen, with a large round black spot at caudal-fin base; Lateral stripe metallic red overlaid with blackish pigment on head, dusky golden on body; Ventral stripe on head also red, suffused with blackish; An iridescent blue-green and blackish spot on side of abdomen just above anus; Body posterior to this spot and adjacent to anal-fin base light red; Back along base of dorsal fins brownish; Fins translucent whitish; Upper part of iris yellow. The stripes (which may be red) are bordered on head with light blue-green except the part of upper border passing through eye which is bright yellow; Lateral stripe on body faintly bordered with light yellow or pink; Black spot at caudal-fin base faintly edged with iridescent blue-green or yellow; Leading edge of first dorsal fin, anal fin, and lateral edge of pelvic fins blue; Remaining fin rays light red, the membranes clear. In some individuals the two anterior dark stripes are nearly solid black, and the lower stripe may continue along ventral side of abdomen to end in the dark spot above anus.
Etymology
Ostorhinchus: from Greek, osteon = bone + from Greek, rhynchos = beak. In reference to the bony jaws, very much advanced and jagged, which take the place of the teeth.
selas: from Greek, selas= fiery meteor. Hayashi and Kishimoto (1983) proposed the Japanese common name Nagareboshi. This name means shooting star in English.
Original description: Apogon selas Randall & Hayashi, 1990 - Type locality: Tripod Reef, lagoon off Nagada Harbor, Madang Province, Papua New Guinea, small coral patches and silty sand, 30 m, rotenone, John E.Randall, 18 November 1987.
Distribution
Western Pacific: Indonesia north to Ryukyu Islands (Japan), southeast to Solomon Islands and New Caledonia.
Biology
Found in sheltered water with low coral growth or coral rubble, on fine silty sand. In small aggregations. Mouthbrooders. Distinct pairing during courtship and spawning.
Similar species
Ostorhinchus ocellicaudus (Allen, Kuiter & Randall, 1994) - Reported from Indo-West Pacific: Indonesia east to Fiji, south to northeastern Australia.
