背面の脊椎 (合計) : 1; 背鰭 (合計) : 5; 臀鰭: 9 - 10; 脊つい: 32 - 33. 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).
Reaches sexual maturity above 5.42 cm SL (Ref. 79512).
