Sudan); Dooley, 1978: 37*.
D VII,15; A 11,12; P 18-19; GR 7+ 13. Body depth 3.3-4.0, head length
3.2-3.9 in SL; eye 4.0-4.8 in head. C margin convex.
Body pinkish brown dorsally, white ventrally; 2 horizontal yellow stripes across middle of C; lower C rays dusky;
red spot on outer base of P and black spot in axil; predorsal
ridge dark brown. Attains 60 cm. In our area known only
from off Durban in 45 - 150 m; also recorded from Red Sea.
Genus Hoplolatilus Gunther, 1887
No fleshy median ridge before D; preopercle serrate; vertebrae 10 or 11 + 14. Species of Hoplolatilus feed on zooplankton and build burrows into which they retreat at the
approach of predators. In their revision of the genus,
Dooley & Randall (1974) recognised 5 species; subsequently 3 more species of Hoplolatilus were described.
One species in our area.

length 3.8-4.0 in SL; eye 3.9-4.4 in head. Preopercle with spine at angle
enlarged. Skinny protuberance on rear margin of gill cavity. Penultimate
D ray prolonged.
Body pale olive-grey, darker dorsally; belly pale blue;
dark bluish violet band joining eyes across front of snout;
lips and cheeks also blue; upper ~ ofP bluish white, remainder pale yellow. Attains 21 cm. In our area, known only
from postlarvae collected off the Cape Peninsula; also reported from India and the western Pacific.

Body elongate, subcylindrical; body depth 5-8 in SL. No
fleshy median ridge before D; preopercle edge smooth;
opercular spine well developed; GR short; vertebrae
10+ 14. All 3 species of Malacanthus build burrows to which
they retreat at the approach of danger; 2 species in our area.
