Etymology: Hoplostethus: Greek, hoplon = weapon + Greek, stetho, stethion = brest; literal = to prick a little breast (Ref. 45335); robustispinus: Name from the combination of the Latin robustus, meaning strong, and spinus, for spine, in reference to the extremely thickened fin spines (Ref. 84133).

Vertebrae: 27. Hoplostethus robustispinus has extremely thickened fin spines, 56 digitiform pyloric caeca, a bright red body, fins with no black pigment in any fin membranes, no silvery flanks, a long trunk (VA distance is greater than almost all other species) and eyes more dorsally placed, with the upper margin dorsal to preopercular ridges and level with the post-temporal spine (Ref. 84133).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01698 (0.00744 - 0.03879), b=3.05 (2.85 - 3.25), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.6 ±0.6 se; Based on size and trophs of closest relatives
Resilience (Ref. 120179
): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): High to very high vulnerability (68 of 100) .
