Lateral line ossicles 66-70; pectoral spine with serrations on the anterior (27-29) and posterior (6-15) edges. Can be differentiated from Sisor chennuah and Sisor torosus in having a more slender body (body depth at anus 5-5.4% vs. 5.6-7.8) and from Sisor rheophilus in possessing a smaller eye (9.4-12.2% HL vs. 13.2-16.3) and a shorter snout (53.9-55.7% HL vs. 56.2-60.3) (Ref. 55921). |
