Diagnosis. A species of the subgenus Ostorhinchuswith VI spines in first dorsal fin; three dark stripes on upper half of head and body, the broadest and midlateral, reaching end of caudal fin, two narrow stripes, the upper stripe reaching to base of second dorsal fin, the lower stripe reaching caudal fin base; no dark stripes in second dorsal or anal fins; 23-26 gill rakers and rudiments; 14 or 15 pectoral rays; blackish stomach and intestine, peritoneum silvery with many melanophores.
Description. See Figure 9 for general body shape and Table 1 for proportional percentages. Dorsal fin VI-I,9; anal fin II,8; pectoral fin usually 14-14 or 15-15 (Table 2); pelvic fin I,5; principal caudal rays 9 + 8; pored lateral-line scales 24, extend from posttemporal onto base of caudal fin; transverse scale rows above lateral line 2;transverse scale rows below lateral line 6; median predorsal scales 6; circumpeduncular scale rows 12 (5+2+5). FIGURE 8. Distribution of collection sites for Apogon bryx, Apogon kiensis, Apogon quinquestriatusand Apogon septemstriatus. Villiform teeth in several rows on the premaxilla; two rows on the dentary; one row on the palatine and vomer; none on ectopterygoid, entopterygoid or basihyal. Rudiments and gill rakers on first arch (Table 3), 1-2 rudiments and 4-6 gill rakers on upper arch, 0-1 rudiments and 17-19 gill rakers on lower arch, 23-26 well developed gill rakers, 21-24 total gill rakers and rudiments. Vertebrae 10 + 14; 5 free hypurals, 1 pair of slender uroneurals, 3 epurals, a free parhypural; 3 predorsals; 1 spine on first dorsal pterygiophore; basisphenoid present; supramaxilla absent; posttemporal serrate on posterior margin; preopercle serrate on vertical and horizontal margins; infraorbital shelf present on third bone. Ctenoid scales on opercle, subopercle, cheek, breast, nape body and pelvic areas; ctenoidpored lateral-line scales from posttemporal to base of hypural; central pore canal on lateral-line scale with 2-3 pores on dorsal side, simple below with 1 pore, rarely with multiple pores. Color in alcohol. Median stripe from interorbit area to predorsal area (may be faint), stripe from interorbit over eye on each side of the body above the lateral line extending to caudal-fin base, a faint narrow stripe beginning behind eye extending to base of caudal fin above midlateral stripe, midlateral stripe (about width of pupil) from snout to end of caudal fin, ventral edge of midlateral stripe on body smooth. No stripes in second dorsal or anal fins. Stomach black, intestine pale with melanophores more intense and appearing black near the anal opening, peritoneum silvery with many melanophores. FIGURE 9. Apogon bryx, USMN 213396, Bay of Bengal, Anton Bruun, 51.9 mm SL. Life colors. Smith (1961) described the living colors of Apogon kiensis(= Apogon bryx) as “Alive silvery grey with dark stripes as in fig. 5. Fins faint pink.”
Distribution. This species reported from 14-155 m in coastal shelf waters of Red Sea, Indian Ocean, Australia and the Philippines (Fig. 8). Smith (1961) reported this species from turbid water.
Remarks. This species has been taken at the same station with Apogon fasciatus(USNM 357476 and 357477). This species differs from Apogon kiensis, a close relative, by having more rudiments and gill rakers (23-26 versus 19-22), and a narrow dark stripe just above the midline stripe between the dorsal stripe (not present in A. kiensis). Fraser (1998) compared Apogon bryxwith western Indian Ocean material which he thought was an undescribed species noting the lack of any dark stripes and 14 pectoral rays as primary differences. The completely faded holotype of A. bryxand the previously undescribed species in the Indian Ocean are conspecific.
