(total): 72-88;
Anal
soft rays: 55 - 70;
Vertebrae: 40 - 45. This species is distinguished by the following characters: D 72-88; A 55-70; moderately large eyes (1.7-2.8%SL); slender body; blunt snout, many cirri; cheeks with scales and rarely 1-2 scales above opercular spine; with upper preopercular pore; outer pseudoclasper broad-based, large, often extending beyond hood when in resting position, while the inner one is small, with equal anterior and posterior lobes; otolith length to height 1.9-2.1, with gently curved dorsal rim; otolith length to sulcus length 1.5-1.6, ostium length to caudal length 3.5-4.5; vertebrae 11-12 + 29-33 = 40-45 (Ref. 81230).
Occurs in holes and crevices of coralline and volcanic rock (Ref. 71230). Cryptic and solitary in shallow water (<12 m) (Ref 90102).

Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00175 - 0.01142), b=3.10 (2.88 - 3.32), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic Level (Ref.
69278): 3.2 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref.
69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref.
59153): Low vulnerability (15 of 100) .
