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..

Short description Claves de identificación | Morfología | Morfometría

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).

Bayesian length-weight: a=0.02692 (0.01216 - 0.05956), b=3.04 (2.86 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nivel trófico (Ref. 69278):  3.3   ±0.4 se; based on size and trophs of closest relatives
Resiliencia (Ref. 120179):  Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
