• Ramphocorixa

  Ramphocorixa is a genus of water boatmen (Corixidae) established by Abbott in 1912, containing at least two described species. The genus includes a notable marine species, R. balanodis, which exhibits extreme morphological adaptations for feeding on barnacles in saltwater intertidal habitats—unusual for a family predominantly found in freshwater. Most species occur in freshwater lakes and ponds across North, Central, and northern South America.
