| Diagnosis |
Can be diagnosed by the unique combination of characters: nasal ossified with narrow medial flanges partially sutured to lateral margin of mesethmoid; anal fin rays iii, 6-7; modified anal fin with short tip in mature males; first unbranched anal-fin ray with segments fused, last branched ray normally developed, not reduced; ribs 10; and vertebrae 35. Differs further by the following coloration details: contour of mouth dark, same color as head; posterior border of nuchal shield usually dark; pectoral-fin spine usually dark brown; body with irregular blotches or stripes; presence of faint stripes or blotches in large specimens ; and caudal fin dark with whitish blotches. Distinguished from Tatia intermedia by having preanal length 70.0-75.0% SL, vs. 65.0-69.4% SL and interorbital distance 54.1-59.4% HL, vs. 60.1-63.6 HL (Ref. 79512). Description: A iii,6-7; V i5. Post-Weberian vertebrae (Ref. 79512). |
