Etymology: Betta: Malay/Javanese origin. Bleeker (1850, 1858) indicates Ikan Wadder Bettah as the local name of Betta trifasciata Bleeker, 1849 (now Betta picta, Valenciennes, 1846) in the Ambarawa Javanese dialect. Ikan Wader is a common Javanese name for smaller freshwater fishes, especially cyprinids (already used in Old Javanese). See Blust, R. & Trussel, S. Austronesian Comparative Dictionary.

背棘 (总数) : 1; 背的软条 (总数) : 8; 臀棘: 2; 臀鳍软条: 26 - 27; 脊椎骨: 31 - 32. Fewer total anal rays than B. balunga (28-29 versus 30). More lateral scales than B. balunga and B. chini (31 1/2-32 1/2 versus 29-31). More lateral scales below dorsal-fin origin (18-19, versus 15-18). Greater total length than B. balunga and B. chini (145.5-153.5% SL, versus 132.8-144.6). Shorter head length than B. balunga (31.3-31.7% SL versus 32.6-35.5). Deeper body depth at dorsal-fin origin than B. akarensis and B. chini (30.6-31.6% SL versus 25.1-30.9). Shorter preanal length than B. balunga (44.7-46.3% SL versus 49.2-52.2).
