Etymology: Pseudojuloides: Greek, pseudes = false + Greek, iouis = a fish without identification, perhaps some of genus Coris cited by Plinius + Greek, oides = similar to (Ref. 45335); atavai: Name from Tahitian word 'atavai' meaning pretty, referring to the attractive coloration of both sexes of the species..

Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 13.0 cm TL male/unsexed; (Ref. 9710)
Dorsal spines (total): 9; Dorsal soft rays (total): 11; Anal spines: 3; Anal soft rays: 12; Vertebrae: 25. This species is distinguished from its congeners by the following characters: body elongate with greatest body depth 22.6-25.3% SL; D IX,11; A III,12; pectoral-fin rays 13; tubed lateral-line scales 28. Colouration: interspinous membrane between anterior two to three spines of dorsal fin has a black spot; males with head yellow and extensively reticulate; abdominal region behind pelvic and pectoral fins is orange to orange-pink with yellow crosshatch markings; posterior part of body purple black; females are distinctly bicolored, orange-brown dorsally, white ventrally (Ref. 123182).
Found well above the bottom of exposed seaward reefs (Ref. 9710) away from lagoons and sheltered bays (Ref. 123182). Feeds on small invertebrates (Ref. 89972).

Estimates based on models
Preferred temperature (Ref.
123201): 24.7 - 26.3, mean 26.1 °C (based on 12 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00470 - 0.02030), b=3.07 (2.89 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 3.4 ±0.4 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.
59153): Low vulnerability (10 of 100).
