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..

The collection area was described by Werner (1990:55-58) as a small stream south of Sao Jose do Xingu (NRM 14605) - a narrow blackwater creek widening at the collecting site and in places 1 m deep; the bottom substrate was sand and mud in part with dense stands of aquatic plants; temperature was 22°C, pH 5.5, conductivity 5 μS. Specimens were taken from quiet shore areas with reed and grass (Ref. 86444).
