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.; egregius: Name from a Latin adjective 'egregius' meaning eminent or distinguished..

Description synthétique Clés d'identification | Morphologie | Morphométrie

This species is distinguished by the lower metamerie meristics than its congeners: dorsal fin count usually XIV.ll instead of XV.l0-l1, anal fin count usually VILlI which is not found in other Mesonauta species, El row scales usually 24 instead of 25 or 26, vertebrae 13+13 instead of 12+14 or 13+14. Bar 6 is split ventrally, but unlike in M. mirificus with similar pattem, there are no horizontal stripes along the sides . It is distinguished from the geographically c!ose M. insignis also by deeper body (50.7-55.6%SL vs 47.6-53.4%SL) and shorter snout (8.9-11.0% vs 1O.2-13.0%SL), and by having plain coloured instead of reticulated dorsal pigment pattern (ref. 86444).

In shallow water among aquatic plants (Ref. 40602).
