Etymology: Centropyge: Greek, kentron = sting + Greek, pyge = tail (Ref. 45335); narcosis: From the Greek 'narke' meaning numbness or torpor, referring to the extreme effects of nitrogen narcosis (experienced by the author and Mr. Boyle while collecting the holotype.

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.03311 (0.01558 - 0.07036), b=2.88 (2.70 - 3.06), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.8 ±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.).
Vulnerability (Ref. 59153
): Low vulnerability (21 of 100) .
