Limnetron is a genus of dragonflies in the family Aeshnidae. It consists of two species: Limnetron antarcticum Förster, 1907, and Limnetron debile (Karsch, 1891), though some experts speculate that there are additional, undiscovered species.[3] They are found in forest streams in Paraguay, south-eastern Brazil, northern Argentina, and Peru.[3]
