Parachartergus

Parachartergus is a genus of epiponine social wasps belonging to the subfamily Polistinae. Species include:

• Parachartergus amazonensis[1]
• Parachartergus apicalis - known to form mutualistic relationships with treehoppers. The male genitalia are noted for their movements of "startling complexity".
• Parachartergus aztecus[2]
• Parachartergus colobopterus - unusually nests contain several queens. The species is docile, preferring to leave the nest than mount an attack.
• Parachartergus griseus (Fox, 1898)[3]
• Parachartergus fasciipennis (Ducke, 1905)[3]
• Parachartergus flavofasciatus[2]
• Parachartergus fraternus (Gribodo, 1892) - closely related to P. apicalis and has been studied extensively
• Parachartergus fulgidipennis[1]
• Parachartergus griseus[2]
• Parachartergus lenkoi[2]
• Parachartergus pseudoapicalis[4]
• Parachartergus richardsi (Willink, 1951)[3]
• Parachartergus smithii[5]
• Parachartergus tomentus[2]
• Parachartergus weyrauchi[2]
• Parachartergus wagneri[2]
