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). More on authors: Randall & Randall.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 12 - 31 m (Ref. 1602). Tropical; 14°N - 28°S
Pacific Ocean: Guam to the Society, Tuamoto, Austral and Ducie islands.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 13.0 cm TL male/unsexed; (Ref. 9710)
soft rays: 12. The primary phase of P. atavai closely resembles juvenile Thalassoma amblycephalum; the terminal phase is orange-yellow anteriorly with dull violet squiggly lines on the head and reddish horizontal and vertical lines on the body, becoming abruptly bluish-black posteriorly (Ref. 1602). Caudal fin not very short (length 1.3 to 1.5 times in head length). First dorsal-fin ray longest. Snout 2.7 to 2.9 times in head length (Ref 9823).
Found well above the bottom of exposed seaward reefs and clear lagoons (Ref. 9710). Feeds on small invertebrates (Ref. 89972).
