| Diagnosis |
The following unique characters separate this species from all other species of Tatia: postcleithral process well developed, reaching almost to a vertical through the dorsal-fin origin; orbital diameter 37.0-42.9% HL; and snout length 23.1-28.9% HL . Can be further distinguished by the following features: narrow elliptical cranial fontanel; ribs 7; nasal ossified with wide medial flanges partially sutured to lateral margin of mesethmoid; coloration variable, sides of body usually dark with light, rounded spots or dots, or sometimes uniformly pale brown; toothed prevomer in examined large adult specimens (Ref. 79512). Description: A iii,6-7; V i5. Post-Weberian vertebrae 32-33 (Ref. 79512). |
