Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 1; Rayons mous dorsaux (Total) : 6; Rayons mous anaux: 6; Vertèbres: 32 - 34. Differs from Sisor rabdophorus and Sisor rheophilus in possessing a deeper body (body depth at anus 5.6-5.8% SL vs. 4.2-5.4). Can be differentiated further from Sisor rheophilus in having a wider head (15.7-15.9% SL vs. 14.5-14.8), shorter snout (54.0-55.9% HL vs. 56.2-60.3), smaller eye (9.9-11.4% HL vs. 13.2-16.3), fewer serrations on posterior edge of pectoral spine (10 vs. 7-22) and wider nuchal plate (width 1.1-1.2 times length vs. width equal to length), and from Sisor torosus in having a more slender body (body depth at anus 5.6-5.8% SL vs. 6.0-7.8) (Ref. 55921).
