This species is not treated in detail except for comparisons with other species, additional specimens and new information under the Description. See Fraser et al. (1999) for additional information.

Diagnosis. A Nectamia   without bars on body, circumpeduncular basicaudal mark in juveniles and adults, caudal fin with dark margins, subocular mark broad, triangular (Tab. 2); 13 pectoral-fin rays; total gill rakers usually 26–29 ( Tab. 1); body depth 41–50%, caudal-peduncle depth 15–20%, second anal-spine length 18– 22%, and pectoral-fin length 26–31% of standard length (Tab 3).

Additional Description. Second gill arch with well developed rakers, 4+18; scales ctenoid on cheek, subopercle, opercle, nape, isthmus, two large scales on base of pelvic fin, rudimentary axillary scale variable present cycloid to few ctenii, cycloid on base of pectoral fin and ctenoid behind pectoral fin, pored lateral-line scales complete, fourth scale with one pore above and one below main canal.

Preserved color pattern. Adults (Tab. 2): wide, triangular subocular cheek mark behind upper jaw; first dorsal fin dark membranes between spines 1–4; edges of caudal lobes dark; caudal peduncle with a complete dark wide bar, connected dorsally and ventrally, body uniform without pale bars; no dark saddle under the first or second dorsal fin; stomach and intestine black. Juveniles: similar to the adults.

Life colors. Kuiter and Kozawa (1999, p.34, A–C) provided three of underwater photographs of this species. Gon and Randall (2003, Pl.1A) published a photograph of a freshly collected specimen. An underwater photograph ( Fig. 6E View FIGURE 6 ) shows the yellowish mark on the lachrymal and anterior infraorbitals, pale body bars, dark edges of dorsal fins, cheek mark and caudal-peduncle marks.

Distribution. Known only from the Red Sea and the Gulf of Aden ( Fig. 7 View FIGURE 7 ).

Remarks. See species comparison under remarks for Nectamia zebrinus   . Günther (1859) used the combination Apogon annularis var. roseipinnis   . Klausewitz (1959) suggested that Apogon annularis   is a subspecies of Apogon aureus   . These subspecies concepts have not been supported by any subsequent work. Klausewitz (1959) and Smith (1961) concluded that Apogon erdmani   is a synonym of Apogon annularis   and Fraser et al. (1999) came to the same conclusion.

Two males in USNM 212429 View Materials exhibited buccal enlargement but no eggs were found in their mouths. This species has been collected at the same stations with Nectamia zebrinus   ( BPBM 19741 View Materials , 30388 View Materials , USMN 212423) in the Red Sea and Gulf of Aden ( USMN 212421). The largest of 400 specimens was 66 mm SL   .
