Diagnostic features: A medium sized Apogonid, with enlarged dark ocellus on the posterior part of first dorsal fin and conspicuous parallel rows of dark brown spots over the body ( Fig. 1 ). First dorsal-fin with VII spines (4 th spine longer than 3 rd spine, 4 th and 5 th spine subequal), second dorsal fin with I spine and 9 rays; anal fin rays II, 8; pectoral fin rays 15, caudal fin rounded, rays segmented. Large ctenoid scales on body; median pre-dorsal scales 2, transverse scales brown spot forming longitudinal rows. An enlarged dark ocellus present on the posterior part of first dorsal fin. Inner lining of stomach and intestine dark; anal fin yellowish, dusky and its distal edge intense black; edges of second dorsal and caudal fin blackish.

Distribution: Western Indian Ocean: southern Red Sea, south and east coast of Africa, Arabian Sea and the Mediterranean Sea 12. From Indian waters it has been reported from the Gulf of Mannar 13, 14, Visakhapatnam 15, along east coast and from Gujarat 11 and Kerala 16 in the west coast of India.

Materials examined: CIFE /KOL/ MW /F-0236, 1 ex., 69.50 mm SL, Location : off Digha coast, India, Date of Coll. 12-09-2016 .

Diagnostic features: Dorsal-fin rays VII + I, 9 (3 rd spine longer than 4 th spine); anal fin rays II, 8; pectoral fin rays 14; pelvic fin I, 5; principal caudal rays 9 + 8, caudal fin forked; lateral line on to caudal, LL 24 (+ 2 on caudal). Very large ctenoid scales on opercle, subopercle, cheek, breast, nape, body and pelvic areas; median predorsal scales 5, two scales between dorsal origin and LL, transverse scale rows below lateral line 7, preopercle bones scaled. Gill rakers 22 (developed 17); branchiostegal rays 5; posttemporal with 4 serrations on posterior margin; preopercle ridge smooth, edges serrate on posterior and ventral margins; infraorbital edge smooth and weak serrations on third infraorbital. Villiform teeth in several rows on the premaxilla; several villiform rows on dentary; 2 rows on the palatine and 2 rows on vomer.

Colour: Body white to dusky pinkish with 3 prominent dark stripes on the upper half of body; dark dorsal stripe from snout over eye ending about middle of second dorsal fin but not passes the second dorsal-fin base, mid-lateral stripe broad, uniform from snout through eye extending to edge of caudal fin, and base of second dorsal fin with thin stripe darker posteriorly up to upper caudal peduncle; an incomplete diffused stripe above mid-lateral stripe. Inner lining of stomach and intestine dark.

Distribution: Red Sea, Indo-West Pacific: East Africa, Seychelles, Madagascar, and Reunion (Mascarenes) south to Mozambique, east to the Philippines and New Guinea, north to southern Japan, south to northern Australia; Mediterranean Sea (Red Sea immigrant) 11.
