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: 24. Differs from B. enisae by: the absence of caudal transverse bars versus presence; more anal rays (25-27, mode 27, versus 23-26, mode 24-25); more subdorsal scales (5 1/2-7, mode 7, versus 5); more lateral scales (28-30, mode 30, versus 26-28, mode 27); smaller predorsal length (62.1-67% SL, versus 67.3-70.3); larger body depth at dorsal-fin origin (28.7-32.8% SL, versus 26.2-28.9); slightly longer pelvic fin (33.9-55.4% SL, versus 33.8-46.7); longer dorsal-fin base (11.4-14.9% SL, versus 8.7-12.1); smaller total length (12.8-15.1% SL, versus 14.3-15.5); smaller orbit diameter (48-69% of postorbital length, versus 57-68); smaller interorbital width (64-74% of postorbital length, versus 70-76) (Ref. 30224). Can be further differentiated from its congeners by: the absence of chin-bar (versus presence in B. pugnax, B. prima and B. pulchra); presence of dark distal borders on anal and caudal fins (versus absence in B. pugnax, B. fusca, B. schalleri, B. prima and B. pulchra; absence of caudal transverse bars (versus presence in B. pugnax and B. pulchra; more anal rays than B. fusca (25-27, versus 24-25); fewer lateral scales than B. schalleri (28-30, versus 31); more predorsal scales than B. schalleri (19-21, mode 21, versus 17-19, mode 19); more postdorsal scales than B. prima (11-12, versus 9-10); greater head length than B. fusca (51.3-54.3% predorsal length, versus 47.2-49.4); smaller predorsal length than B. fusca and B. prima (62.1-67% SL, versus 68.1-70.2); smaller postdorsal length than B. prima (21.9-23.4% SL, versus 24.1-26.3); smaller preanal length than B. prima (48-51.5% SL, versus 50.6-54.8); greater body depth than B. schalleri (28.7-32.8% SL, versus 26.7-27.6); longer pelvic fins than B pugnax (filamentous tip reaching 9-18th anal ray, versus 4-10th; 33.9-55.4% SL, versus 26.6-43.8); longer anal-fin base than B. fusca and B. schalleri (51.1-54.5% SL, versus 47.8-52); smaller orbit diameter than B. pugnax and B. pulchra (24.2-28.5% HL, versus 27.9-38.5); smaller interorbital width than B. pugnax and B. pulchra (29.6-36.1% HL, versus 32.4-53) (Ref. 30224).
有别于 B. enisae 被: 那缺乏尾部的横跨横带和出现比较; 更多的臀鳍鳍条;(25-27 ，模态 27, 对 23-26, 模态 24-25) 比较子背部的鳞片;(5 1/2-7 ，模态 7, 对 5) 比较侧面的鳞片;(28-30, 模态 30, 对 26-28, 模态 27) 比较小的前背长度;(62.1-67% SL, 对 67.3-70.3) 在背鳍起点的较大的体高;(28.7-32.8% SL, 对 26.2-28.9) 些微比较长的腹鳍;(33.9-55.4% SL, 对 33.8-46.7) 较长的背鳍基底;(11.4-14.9% SL, 对 8.7-12.1) 较小的全长;(12.8-15.1% SL, 对 14.3-15.5) 较小的眼窝直径;(48-69% 的眼眶后的长度, 对 57-68) 较小的眼间骨宽度 (64-74% 的眼眶后的长度, 对 70-76).(参考文献 30224) 可能是进一步与它的同类区别藉着: 那缺乏下巴-横带;(对出现在 B. pugnax 中, B. 主要的 与 B. pulchra) 在臀鳍与尾鳍上有深色的末梢部的边缘 (对缺乏在 B. pugnax ， B. fusca ， B. schalleri 中, B. 主要的 与 B. pulchra; 缺乏尾部的横跨横带 (对出现在 B. pugnax 与 B. pulchra 中; 更多的臀鳍鳍条超过 B. fusca;(25-27, 对 24-25) 超过 B. schalleri 的少侧面的鳞片;(28-30, 对 31) 超过 B. schalleri 的比较前背的鳞片;(19-21, 模态 21, 对 17-19, 模态 19) 超过 B. 主要的 的比较后背的鳞片;(11-12, 对 9-10) 超过 B. fusca 的较大的头长;(51.3-54.3% 前背的长度, 对 47.2-49.4) 超过 B. fusca 与 B. 主要的 的小前背的长度;(62.1-67% SL, 对 68.1-70.2) 超过 B. 主要的 的小后背的长度;(21.9-23.4% SL, 对 24.1-26.3) 超过 B. 主要的 的较小的肛门前部分的长度;(48-51.5% SL, 对 50.6-54.8) 超过 B. schalleri 的较大的体高;(28.7-32.8% SL, 对 26.7-27.6) 超过 B pugnax 的较长的腹鳍 (丝状的顶端达到 9- 第 18个臀鳍鳍条, 对 4- 第 10; 33.9-55.4% SL, 对 26.6-43.8); 超过 B. fusca 与 B. schalleri 的较长的臀鳍基底;(51.1-54.5% SL, 对 47.8-52) 超过 B. pugnax 与 B. pulchra 的较小的眼窝直径;(24.2-28.5% HL, 对 27.9-38.5) 超过 B. pugnax 与 B. pulchra(29.6-36.1% HL, 对 32.4-53) 的较小的眼间骨宽度.(参考文献 30224)
