Tribe Zoramiini new name Fraser & Mabuchi

Type genus Zoramia Jordan 1917

Diagnosis. Members of the Apogoninae: dorsal fin VI–I,9; anal fin II,8–9; head and body with ctenoid scales; pored lateral-line scales 24; preopercle ridge smooth, edges serrate; three supraneurals; supramaxilla absent; basisphenoid present; anterior pair of uroneurals; three epurals; five free hypurals; parhypural separate; two autogenous haemal spines; one supernumerary dorsal spine; caudal fin forked.

Other characteristics. first segmented fin-ray in second dorsal-fin branched, first anal-fin ray branched and segmented; second dorsal spine longest, very long and filamentous in some species of both genera; ctenoid scales on predorsal, cheek, breast, two pelvic scales, and body; ctenoid scales on opercle and onto base of caudal fin; cycloid or ctenoid predorsal scales1–3; pored lateral-line scales simple with one pore above and one below midline; pectoral-fin rays 13–17; 9+8 segmented principal caudal rays, 15 branched, upper and lower unbranched; developed gill rakers 7–38; unbranched procurrent rays, longest segmented; 10+14 vertebrae; 8 ribs; 7–8 epipleurals; teeth in one, two or multiple rows on premaxilla, dentary, vomer, palatine, all villiform; six infraorbitals, bony shelf absent or on third infraorbital; stomach and intestine black with silvery peritoneum; low crest on PU2.

Distribution. Species of Zoramia are known from East Africa, Red Sea, islands in the Indian Ocean, throughout the West Pacific to Japan, onto the Pacific Plate to Marshall Islands, Samoa, Tonga, Solomon Islands, New Caledonia and Australia. Species of Fibramia are known from East Africa, some islands in the Indian Ocean, Sri Lanka, throughout the West Pacific to Philippines, Solomon Islands, Santa Cruz Islands, Fiji, Vanuatu, New Caledonia, Australia, Samoa and Tonga.

Remarks. This tribe contains two genera, a new genus Fibramia described below and Zoramia, corresponding to the clade VIII in the molecular trees (Figs. 2–6, Table 4). Both genera have species with elongate second dorsal spine, a single supernumerary dorsal spine, and can be found in tidal fresh and brackish water, near shore waters and in lagoons. Fibramia corresponds to the clade of Ostorhinchus - 4 in the present study, and that of Ostorhinchus I in Mabuchi et al. (2006).
