Dorsale stekels (totaal) : 7; Dorsale zachte stralen (totaal) : 14 - 15; Anale stekels: 15 - 16; Wervels: 26. This species is distinguished by the following characters: D VI + I,14-15; A I,15-16; caudal fin is strongly lanceolate, and is longer than head length; longitudinal scales 80-86; transverse scales 24-26; body scales entirely cycloid; scaleless on head, including side of nape and upper opercle; when alive grayish-brown with 2 orange-brown stripes on head and body, short upper stripe, ending before soft dorsal fin, the lower stripe horizontally ovate, orange-brown spot on opercle, continuing as a pale body stripe from upper pectoral-fin base to middle of caudal-fin base; pectoral-fin base pale with small, rectangular dark orange-brown spot across middle portion; series of 8-11 small black spots or saddles on upper back (Ref. 114936).
Occurs on silt-mud substratum in highly sheltered bays and lagoons; loosely scattered, mainly solitary individuals were encountered at the type locality; invariably associated with muddy burrows where they retreat when closely approached by divers (Ref. 114936).

Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00333 - 0.01504), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.0 ±0.2 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
