Short description
पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय रीढ़ (सम्पूर्ण) : 2; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 7; गुदा कांटा: 1; ऐनल सौफट रेज़: 4. This species is distinguished by the following characters: teeth bifid teeth (vs. spoon-shaped); dark spots on a light background (vs light spots on a dark background or not spotted); 4 rough lateral ridges on flanks (vs. absent); 26-29 lateral series plates (vs. < 28 in several species, 31-32 in H. laplatae); 1-2 plates bordering posterior margin of the supraoccipital bone (vs. 3-4 in H. laplatae); differs from H. affinis, H. punctatus, H. ancistroides by having inter-dorsal distance 14.4-19.5% in SL (vs. 18.9-21.0%); head depth 49.0-71.6% in HL (vs. 48.2-49.9); differs from H. spiniger by having fine lateral ridges with odontodes posteriorly inclined (vs. large lateral ridges with odontodes in all directions), weak lateral ridges in caudal peduncle (vs. strong), mid lateral ridge from first plate (vs. ridge from 2nd or 3rd plates); adult of this species (> 12.0 cm SL) can be distinguished from adult H. spiniger by having a strong ridge on temporal plate (vs. very week) (Ref. 121236).
Facultative air-breathing in the genus (Ref. 126274); Occurs in rivers where substrate from which specimens were obtained was composed chiefly of muddy sand. This species was found in moderately oxygenated waters (6.1-9.1 mg/l) with moderate current; water turbidity 23.7-442 NTU, conductivity 1.087-2.654 μS/cm, pH 7.2-9.2, and temperature 16.8-27.8°C (Ref. 121236).
