Maturity: Lm ?  range ? - ? cm
Max length : 4.6 cm SL самец/пол неопределен; (Ref. 38376)
членистые (мягкие) лучи спинного плавника (общее число) : 10; членистые (мягкие) лучи анального плавника: 14 - 20. The possession of a dark, vertically elongate humeral bar in mid-sized and larger specimens or the presence of a diffuse patch of chromatophores in that region in the smaller individuals examined distinguishes Attonitus irisae from Attonitus bounites and Attonitus ephimeros. Dorsal fin with 2 unbranched and 8 branched ray. Anal fin with 3 unbranched and 14-17, most commonly 15-16, branched rays (Ref 53400).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00443 - 0.02057), b=3.06 (2.88 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.0 ±0.4 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref.
120179): высокий, минимальное время удвоения популяции до 15 месяцев (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
