Euchirinae

Euchirinae is a subfamily of Scarabaeidae or scarab beetles in the superfamily Scarabaeoidea. They are sometimes referred to as "long-armed scarabs" due to the elongated forelegs of the males. These long legs often have median and apical spines that are fixed in the male while females have a movable terminal spine.

They are sometimes included in Subfamily Melolonthinae as Tribe Euchirini.
