Etymology: Pareutropius: Greek, par = beside, near + Greek, eu = well + Greek, tropis = keel, in reference to the compressed body of the fish; longifilis: From the Latin "longus" (long) and "filum" (filament), referring to the long barbels of this species (Ref. 43912).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00269 - 0.01291), b=3.03 (2.84 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Low, minimum population doubling time 4.5 - 14 years (Assuming fec < 100).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
