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. Web Edition (https://www.trussel2.com/acd/).; pulchra: The Latin pulcher means handsome, alluding to the beauty of this fish..

背棘 (总数) : 1 - 2; 背的软条 (总数) : 8 - 9; 臀棘: 1 - 2; 臀鳍软条: 22 - 26; 脊椎骨: 29. In comparison with other members of the B. pugnax species group, this can be differentiated by the following combination of characters: presence of chin-bar; absence of dark marks below postorbital stripe on opercle; presence of dorsal transverse bars; caudal transverse bars present only in male; greenish iridescent scales on opercle and body; anal fin with red subdistal border and black edge; caudal fin without distal dark edge; anal-fin rays 24-28 (mode 26); lateral scales 28-30 (mode 29); postdorsal scales 10-11 (mode 10); pelvic fin length 29.1-53.2% SL; head length 32.7-37.6% SL; inter-orbital width 34.3-41.8% HL (Ref. 56613).
和 B. pugnax sensu stricto 比较起来，它明显比较矮胖的 (背部的深度 25.9-36.9 和 24.8-32.1% SL 比较), 在身体上持有更多的彩虹色的鳞片活着时, 尾鳍狭窄矛尖形与背部, 尾部的, 臀鳍与腹鳍鳍比例上比较长.(参考文献 13220)
