| Max. size: |
12 cm SL (male/unsexed) |

South America: Araguaia, Tocantins, Xingu and Capim rivers, tributaries of the lower Amazon of Brazil, northwards to the Suriname coastal rivers and the Essequibo River in Guyana. |
| Diagnosis: |
Dorsal spines (total): 1-1; Dorsal soft rays (total): 4-5; Anal soft rays: 9-10; Vertebrae: 35-36. Differs from other species by having a wide elliptical cranial fontanel; short postcleithral process not reaching vertical through origin of dorsal fin; body coloration variable, usually with
elliptical spots along sides of body, large specimens with faint spots; or color pattern uniformly pale brown; and caudal fin with small spots or pale brown. The only other Tatia with a
variable coloration is Tatia galaxias, but this species differs from Tatia galaxias by its short postcleithral process ; its small eye, 21.4-26.3% HL and its long snout 38.8-44.3% HL. Can be further diagnosed by the following characters: nasal ossified with wide medial flanges partially sutured to lateral margin of mesethmoid and caudal-fin lobes of mature females with same length, but mature males with elongated upper lobe are other distinguishing features (Ref. 79512).
