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.. More on author: Kullander.

Short description Morphology | Morphometrics
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).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805): PD50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.03162 (0.01410 - 0.07093), b=3.01 (2.82 - 3.20), based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278): 3.3 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153): Low vulnerability (12 of 100) .
