This species has been informally referred to as "Trimma RW sp. 53 (in lit.)."..

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=0.01023 (0.00477 - 0.02194), b=3.02 (2.84 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
