南美洲: 亞馬遜河流域與圭亞那的河。
大小 / 重量 / 年龄
Maturity: Lm ?  range ? - ? cm
Max length : 12.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 37098)
背棘 (总数) : 1; 背的软条 (总数) : 4 - 5; 臀鳍软条: 9 - 10; 脊椎骨: 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).
Inhabits rivers (Ref. 27188). Reaches sexual maturity above 5.04 cm SL (Ref. 79512).
栖息于河。 (参考文献 27188)
