Dorsale stekels (totaal) : 1; Dorsale zachte stralen (totaal) : 5; Anale zachte stralen: 9; Wervels: 31 - 32. The presence of large pale blotches over a dark brown base coloration separates this species from its congeners, except Tatia aulopygia, Tatia brunnea, Tatia dunni, Tatia galaxias, Tatia intermedia, and Tatia neivai. Differs from these species by having the combination of the following characters: anal fin-fin rays of mature males uniformly decreasing in size from third unbranched ray; caudal fin uniformly dark brown or with several dark brown chromatophores irregularly widespread, forming roundish blotches, and rarely forming stripes; caudal fin in juvenile individuals uniformly dark brown ; brown caudal-fin dots arranged as stripes (in some specimens), which might be confused with pale striae to roundish dots on caudal fins of some Tatia neivai; humeral process long, reaching or surpassing the vertical line through origin of dorsal fin; 31 or 32 post-Weberian vertebrae and 9 or 10 ribs; and 3-5 hemal spines with thicker distal portion (Ref. 81205).
