Diagnosis |
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). Description: A iii,6-7; V i5. Post-Weberian vertebrae 35-36 (Ref. 79512). |
