Dorsale stekels (totaal) : 1; Dorsale zachte stralen (totaal) : 5 - 6; Anale zachte stralen: 6; Wervels: 33 - 35. Differs from other members of the genus in having a relatively deep body (body depth at anus 6.0-7.8% SL vs. 4.2-5.8), anterior edge of pectoral spine with 29-34 serrations while posterior edge with 12-18 serrations. Can be differentiated further from Sisor rheophilus in having a wider nuchal plate (width 1.2-1.3 times length vs. width equal to length) (Ref. 55921).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00676 (0.00307 - 0.01489), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
