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/).; omega: Name from Greek 'omega', i.e., alluding to the peculiar throat pattern and referring to the last members of this species in the disappearing black water habitat type; noun in apposition (Ref. 127779).

This species is distinguished from its congeners by the following set of characters: black markings on lower jaw that are continuous with two black downward curved bars on the anterior throat, ending with rounded bulging ends near edge of lower jaw resembling a distinct omega (?) pattern; opercle uniform brown with light dark brown mottling, operculum without lower distal margin black; black transverse bars on the dorsal and caudal fin interradial membranes; absence of a dark distal border on anal fin (Ref. 127779).

This species is currently recorded only from the remnant black water swamps in Johor, Malaysia. Maximum length based on type specimen, to be replaced with a better reference (Ref. 127779).
