Dorsal spines (total): 14-16; Dorsal soft rays (total): 6-9; Anal spines: 3-3; Anal soft rays: 7-9; Vertebrae: 25-27. This small badid species, barely exceeding 2.0 cm SL, is distinguished from its congeners by the following characters: zigzagging bars, which are formed by darkly pigmented posterior scale margins involving usually three scale rows; among Myanmar species of Dario, further differs from D. hysginon and D. tigris by having more vertebrae modally 26 (vs. 25 in D. hysginon, 24 in D. tigris) and a genetic divergence of 15.6-19.0 % uncorrected p-distance in the COI gene (Ref. 137632). |
