See text 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.

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.
