(total): 7 - 8;
soft rays: 12;
Vertebrae: 26 - 27. This species is distinguished by the following characters: no antrorse AIO spine, long (20-28%SL); pectoral fin reaches just beyond anal fin origin (32-36% SL); eye large (11-15% SL); pterygiophores exposed along base of D1 (large plates including one in advance of first D1 spine) and D2 fins with small spines at ray bases that are directed anteriorly (Ref. 95016).
Inhabits continental shelves and insular areas. Rare deepwater species.
