Etymology: Pteropsaron: Greek, pteron = wing, fin + Greek, psaron = grey, with different colours (Ref. 45335); longipinnis: The name refers to the elongate dorsal and pelvic fins,especially the latter which defines it from the nearest relative P. springeri.

Estimates based on models
Preferred temperature (Ref. 115969
): 24.4 - 26.1, mean 25.9 °C (based on 5 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±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.).
Vulnerability (Ref. 59153
