Etymology: Mesonauta: Name not explained by Günther; probably from the Greek 'mesos' meaning middle or average, and 'nautes' for sailo (alternatively from Latin 'nauta' or sailor; the name perhaps refers to he position of dorsal fin origin posterior to the pelvic fin which was the author's principal diagnostic character; mirificus: Named from a Latin adjective 'mirificus' meaning wonderful (Ref. 86444).

Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
This species is distinguished from its congeners by its colour pattern: bar 6 including a light vertical stripe that usually divides the bar into two narrow parallel stripes below the middle of the side, and narrow dark horizontal lines along the side. It is similar to M. egregius in having bar six doubled, but with 8 or 9 (vs. 6 or 7) anal fin spines (Ref. 86444).
In blackwater rivers, among plants (Ref. 40602).
