Caliscelidae is a family of
planthoppers, sap-sucking insects that belong to the order
Hemiptera, suborder
Auchenorrhyncha and superfamily
Fulgoroidea. They are somewhat anomalous and have often been included within the family
Issidae. Studies made in 2013 of the
phylogeny of the Issidae and other groups using molecular techniques support the treatment of the group as a separate family.[1][2] Sexual dimorphism can be marked. Some members of the family are called
piglet bugs due to the shape of their
snout.[citation needed] A particularly aberrant genus described in 2011 from India, Formiscurra, has males that resemble ants.[3]
