Etymology: Plesiops: Greek, plesios = near + Greek, ops = appearance (Ref. 45335); insularis: From the the Latin word meaning 'of islands', referring to the present distribution of the species , in the islands of the New Caledonia Basin region. More on authors: Mooi & Randall.

Marine; reef-associated; depth range 0 - 25 m (Ref. 27772), usually 2 - 25 m (Ref. 27772). Temperate
Southwest Pacific: islands in the Coral and Tasman seas, including Lord Howe Island and the nearby Elizabeth and Middleton reefs, Norfolk Island, New Caledonia, and Chesterfield Bank. Western Central Pacific (Ref. 12926). Recently reported from Tonga (Ref. 53797).

Estimates based on models
Preferred temperature (Ref. 115969
): 24.4 - 27.3, mean 26.1 °C (based on 94 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01096 (0.00437 - 0.02753), b=2.98 (2.76 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.5 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.).
Vulnerability (Ref. 59153
): Low vulnerability (25 of 100) .
