Espinhos dorsais (total) : 12; Raios dorsais (total) : 20; Espinhos anais: 2; Raios anais : 20; Vértebras: 36 - 37. This species is distinguished by the following set of characters: head and body with 2 dark lateral stripes, the lower one broadly extending onto the anal fin; dorsal fin with basal 4/5 to 2/3 of fin very dark and superimposed by 5 or 6 approximately equally spaced pale spots, the first spot conspicuous, discrete, and round, the others diffuse and partially extending onto the dorsum; dorsal fin XII, 20 (Ref. 58774).
Collected using rotenone and hand-nets from sand and rubble slope with scattered outcroppings, below base of a vertical reef drop-off, with vertical grooves and small holes and caves, 67-110 meter depth (Ref. 58774). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).
