soft rays: 89 - 94. Snout rather blunt; eye diameter almost as long as snout; opercular spine strong and straight; hind margin of preopercle usually with 3 sharp spines; 1 median (broad) and a pair (larger and overlapping median one) of basibranchial tooth patches; pseudobranchial filaments 2 or 3; 7-15 developed rakers on anterior arch; lower 5-11 pectoral fin rays free and longer than upper ones; precaudal vertebrae 13-16 (Ref. 34024). No black fin rays; spines in supraorbital absent and on preopercle absent or weak (Ref. 34024).
Eastern Atlantic: known only from off Namibia.
Rare species (Ref. 34024). Reproductive strategy possibly similar to other members of this family featuring oviparity, with oval pelagic eggs floating in a gelatinous mass (Ref. 205).
