Etymology: Grallenia: Named for Gerald R. Allen, (G+R+Allen+suffix '-ia'), in honor of his great contribution to our knowledge of the diversity of coral-reef fishes; compta: Name from Latin 'compta' meaning ornamented); referring to the orange markings on the head, body, and fins; treated as a feminine singular adjective.
Eponymy: Dr Gerald Ray Allen (d: 1942) The genus was named to honour “…his great contribution to our knowledge of the diversity of coral-reef fishes.” (See Allen, GR) (Ref. 128868), visit book page.

Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 7; Dorsal soft rays (total): 8 - 9; Anal spines: 8 - 9; Vertebrae: 27. This species is distinguished by the following characters: D VI + I,8-9; A I,8-9; the first dorsal fin is fully erect and rectangular, first spine not produced into filament in either sex; no head pores; posterior longitudinal scales 15-20, usually extending forward to about level of second dorsal-fin origin, but body anterior to level of middle of second dorsal fin mainly scaleless; body depth at pelvic-fin origin 14.0-16.4% SL; colour in life translucent with scattered orange-brown to orange markings consisting of a mid-lateral row of short, horizontal, orange-brown lines; small orange spots on the back, a row of horizontally ovate spots on lower side; iris pinkish orange and 4-5 dark-brown spots on dorsal scleral surface of each eye; fins translucent with numerous white speckles, sometimes with a pair of orange stripes on first and second dorsal fins (Ref. 116128).
Occurs in large (5-10 m2 ), flat, sandy areas surrounded by live coral at about 14-15 m (Ref. 116128).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00339 - 0.01546), b=3.10 (2.92 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 3.0 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
