deskripsi pendek Kunci identifiaksi (pengenalan) | Morfologi | Morfometrik

Duri punggung (Keseluruhan (total)) : 11 - 16; duri punggung lunak (Keseluruhan (total)) : 12 - 13; Duri dubur: 2; vertebrata, bertulang belakang: 44 - 45. Distinguished from all congeners, except Percina macrocephala, by having a sickle-shaped suborbital bar and a black bar subtending a medial black spot on the caudal-fin base. Differs from Percina macrocephala by having larger scales (usually 24-26 scales around the caudal peduncle vs. 27-31), 21-23 transverse scales (vs. 23-26), and 70-77 lateral scales (vs. 76-86). Has values for the combination of caudal peduncle, transverse and lateral scales and lateral scales usually 120-129 (vs. 128-141); has shorter snout on average; snout ranges from 20-28% of HL compared to 24-31 in Percina macrocephala (Ref. 75766).
