Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
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).
