Etymology: Oreoglanis: Greek, oreos = mountain+Greek, glanis = Latin, aurum = gold + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish (Ref. 45335); hypsiura: Specific name from the Greek hypos which means high, and oura which means tail, in reference to the relatively deeper caudal peduncle compared to O. delacouri.

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00264 - 0.01315), b=3.08 (2.88 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
