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/).; stiktos: From the Greek noun stiktos meaning dappled, spotted, in reference to the rows of diagnostic round spots on the dorsal fin..

背的软条 (总数) : 10 - 11; 臀鳍软条: 27 - 29. Diagnosed from other members of the Betta splendens group by the following combination of characters: up to 5 rows of black rounded marks on interradial membranes of dorsal fin; up to 9 rows of transverse black bars on caudal fin; up to 7 vertical rows of dark marks on posterior edge of scale on body; lateral scales 33-34 (mode 33), predorsal scales 24-25 (mode 25); postdorsal length 17.5-20.1% SL; body depth 26.2-27.7% SL; caudal peduncle depth 15.4-17.4% SL; length of dorsal-fin base 15.2-15.6% SL; orbit diameter 27.7-29.7% HL; postorbital length 45.9-50.0% HL; interorbital width 26.4-31.6% HL (Ref. 56613).
鉴定了 五彩搏鱼〔Betta splendens〕 群的与其他成员藉由跟随组合特征: 在背鳍的间辐膜上向上到 5 列的黑色圆形的标志; 在尾鳍上向上到 9 列的横跨黑色的横带; 在身体上的鳞片的后缘上向上到 7个呈纵向列的深色印记; 侧面的鳞片 33-34(模态 33), 前背的鳞片 24-25(模态 25); 后背的长度 17.5-20.1% SL; 体高 26.2-27.7% SL; 尾柄深度 15.4-17.4% SL; 背鳍长基底 15.2-15.6% SL; 眼窝直径 27.7-29.7% HL; 眼眶後的長度 45.9-50.0% HL; 眼間骨寬度 26.4-31.6% HL.(參考文獻 56613)
