Etymology: Priolepis: Greek, prio = to saw + Greek,lepis = scale (Ref. 45335); eugenius: Origin of name unclear; either from Greek 'eugenes' for well-born or noble, or less likely from Greek 'eu' for true or original and Latin 'genius', the protecting attendant spirit of a person or place. Both interpretations do not seem especially appropriate for this drab little fish (Ref. 10753) More on authors: Jordan & Evermann.

Estimates based on models
Preferred temperature (Ref. 115969
): 24.4 - 25.5, mean 25.2 °C (based on 45 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00475 - 0.02204), b=3.03 (2.85 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.2 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 (14 of 100) .
