Description:

Dorsal spines: 10; Dorsal rays: 13; Anal spines: 3; Anal rays: 9.

Body elongate to moderately deep and laterally compressed. Head relatively small with pointed snout. Snout-forehead profile almost straight. Pair of small rounded nostrils 
on each side of snout with very low flap on outer edge of anterior nostril. Pair of canine teeth anteriorly in upper jaw, with smaller canine teeth between these and 
symphysis. Remaining lateral portion of upper jaw with series of embedded caniniform teeth. Lower jaw with about 6‒8 small canine teeth on each side. Dorsal-fin outline 
slightly incised. Predorsal scales extending forward to vertical at posterior margin of pupil. Scale rows on back rising obliquely above lateral line. Lateral-line scales 
49–51. Horizontal scale rows above lateral line 6–7. Scale rows on cheek 7–8. Scales absent on preopercular flange. Profile of soft dorsal-fin relatively low and weakly 
rounded. Pectoral fins pointed. Caudal fin emarginate.

Colour. Pinkish-white base colour, becoming darker reddish-pink dorsally and down snout, and paler ventrally. A series of narrow yellow horizontal stripes (one per scale row) 
on lower sides of body below the lateral line. The mid-lateral stripe originating at the mid-eye distinctly more prominent and wider, 1.5‒3 scale rows wide. Similar thin 
yellow to brownish yellow lines above lateral line, but run obliquely upward and along oblique scale rows. Dorsal, caudal, anal, and pectoral fins yellow (caudal fin 
frequently dusky when fresh). Pelvic fins whitish with yellow tinge. Iris reddish to golden yellow.


Size:

Maturity: Lm unknown. Range unknown. Max Length: 30 cm TL, Commonly to 20 cm TL.


Habitat and Ecology:

Inhabits coastal coral and rocky reefs and outer slopes (depth 5-90 m). Forms large and small aggregations around outcrops. Diurnal carnivore. It is a broadcast spawner and 
tends to spawn in groups.


Fishery Status:

This species is not protected or subject to fishery regulations. It is caught in the fish trap fishery and is a regular and sometimes numerous component of the catch.


Notes:

L. madras is 1 of 7 species in the Yellow-lined snapper complex. L. vitta and L. Lutjanus are also documented as occurring in Seychelles (Allen 1984, 1985) and can be 
distinguished from L. madras as per the characteristics tabulated below (adapted from Iwatsuki 2015).
