Ricaniidae

Definition

A family of planthoppers (Hemiptera: Fulgoroidea) comprising over 400 described species, characterized by broad, often patterned wings and a compact body form. Members occur predominantly in tropical Africa, Asia, and Australia, with limited representation in the Palearctic and Neotropical realms. Ricaniids are distinguished from other fulgoroid families by wing venation patterns and male genitalic structures used in species-level taxonomy.

Etymology

Example

The African species *Ricania simulans* (Ricaniidae) is a notable pest of coffee and citrus, where nymphs and adults feed on phloem sap and excrete honeydew that promotes sooty mold growth.

Usage Notes

Family name is always capitalized and italicized (or underlined) following zoological nomenclature convention. Sometimes confused with the related family Flatidae, which shares similar broad-winged morphology; Ricaniidae typically lack the reticulate wing venation and more extreme body flattening of flatids. The family's phylogenetic placement within Fulgoroidea remains under study, with some molecular analyses suggesting closer affinity to Nogodinidae or Tropiduchidae than to Flatidae.
