Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 8; Raggi dorsali molli (totale) : 9; Spine anali: 2; Raggi anali molli: 8. This species is distinguished by the following characters: body with variable sized brownish spots in size (on jaws, snout, interorbital, nape, preopercle, subopercle, and abdomen); a dark wedge-shaped bar below the eye; rows of small brown dots, one per scale, in three rows - the uppermost along lateral line, the middle along lateral midline from behind opercle flap to mid-caudal peduncle, and the third parallel to second, from behind pectoral fin to above middle of anal fin; a large dark blotch on distal membranes of third and fourth dorsal-fin spines; with a small dark-brown spot on body at the base of last two branched dorsal-fin rays; a brownish stripe in second dorsal fin, transparent above and below, anal fin without stripe; pectoral-fin rays 14; median predorsal scales on nape 3; gill rakers1 + 8 ,3 upper and 3 lower rudiments; multicolored iris in life (Ref. 118651).
The two known specimens were collected from under a piece of dead-coral rubble on a gradually sloping sand bottom at 40 m depth (Ref. 118651).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00528 - 0.02384), b=3.10 (2.92 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.5 se; based on size and trophs of closest relatives
Resilienza (Ref.
120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
