Morphology | Morphometrics
soft rays: 4. This species is distingusied from its congeners by the following characters: teeth bifid (vs. spoon-shaped); dark spots on a light background (vs. light spots on a dark background or not spotted); without 4 rough lateral ridges on flanks (vs. strong ridges present in H. commersoni, H. spiniger, H. laplatae); plates in lateral series 28-30 (vs. < 28 in several species or 31-32 in H. laplatae); body height 13.3-18.1% in SL and head length 25.9-30.7 in SL (vs. 17.724.7% and 27.5-38.7, respectively in H. commersoni, H. spiniger, H. laplatae) (Ref. 121236).
The specimens were recently collected from seven rivers, where the substrate was mainly composed of sandstone boulders with patches of coarse sand and pebbles. It was found in well-oxygenated waters (6.9-11.2 mg/l) with strong current; water turbidity 1.29-75.1 NTU, conductivity 77-4.530 ?S/cm, pH 7.8-8.8, and temperature 20.7-31.4°C (Ref. 121236).
