Harpactorini is the most diverse tribe within the assassin bug Reduviidae, containing 289 and approximately 2000 globally. The tribe is distinguished by several genera exhibiting exaggerated pronotal modifications, including the wheel-shaped pronotum of Arilus and the strongly raised, divided pronotal lobe in Ulpius.
