Dorsale stekels (totaal) : 7; Dorsale zachte stralen (totaal) : 8; Anale stekels: 1; Anale zachte stralen: 8. Distinguished from all other species of the genus by the following combination of characters: D1 VI, D2 I, 8, A I, 8, P 15-16; complete body squamation, lateral line scales 32-33; cephalic lateral-line system: anterior oculoscapular canal much reduced, ending between eyes with or without pores')… (if pore')… is present then a pore ')…' is present too), with pore K (always paired), with pore a and always with pore a'; preopercular canal absent; oculoscapular row z separated in two sections; paired interorbital row p present; eyes large, interorbital space distinctly smaller than eye diameter; coloration of first dorsal fin: adult females with a broad dark band on distal third, adult males with two dark spots (Ref. 26720).
Occurs in freshwater spring and small brook flowing towards nearby lagoons; also in associated wetlands. No biological data available (Ref. 59043). Is threatened due to water abstraction and pollution (Ref. 26100).

Estimates based on models
Fylogenetische diversiteitsindex (Ref.
