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).Description: Anal-fin rays iii,6 (males), ii,7 (females); pelvic fin i,5. Post-Weberian vertebrae 31or 32 (Ref. 81205). Pavanelli, C.S. and A.G. Bifi 2009 A new <i>Tatia</i> (Ostariophysi: Siluriformes: Auchenipteridae) from the rio Iguaçu basin, Paraná State, Brazil.
