Các tia vây lưng cứng (tổng cộng) : 1; Các vây lưng mềm (tổng cộng) : 4 - 5; Tia mềm vây hậu môn: 9 - 10; Động vật có xương sống: 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).
Body shape (shape guide): elongated.
Inhabits rivers (Ref. 27188). Reaches sexual maturity above 5.04 cm SL (Ref. 79512).
