🐟 Physical Description

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 .: short and / or deep.
