Short description
Morfologia | Morfometria
Spine dorsali (totale): 30 - 33; Raggi dorsali molli (totale): 84-98; Raggi anali molli: 78 - 89; Vertebre: 91 - 94. Diagnosis: 29+1 - 32+1 (median 31+1) dorsal spines; postorbital length 60.9-65.0% HL (mean 62.8%); pectoral fin 23.1-27.2% HL (mean 25.2%); distance from anterior border of snout to last externally visible dorsal spine relatively long, 55.6-59.9% SL (mean 58.2%), decreasing with size; origin of soft dorsal fin at about same level as origin of soft anal fin; lower jaw relatively short, its length 14.4-23.1% HL (mean 18.3%), increasing with size; anterior origin of first dorsal spine situated before or just above posterior edge of pectoral fin, (- 12.2)-0.0% HL [mean (- 5.7%)]; distance from gill opening to dorsal pectoral fin base 4.3-9.6% HL (mean 6.9%) (Ref. 81678).
Inhabits slow streams with sandy bottoms (Ref. 6060). Maximum reported total length 392 mm (Ref. 81678).

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=0.00257 (0.00122 - 0.00544), b=2.97 (2.79 - 3.15), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.9 ±0.6 se; based on size and trophs of closest relatives
Resilienza (Ref.
