Psorothoracinae

Psorothoracinae is a subfamily of the insect order Hemiptera, commonly known as true bugs. This subfamily belongs to the family Cicadellidae, which are also referred to as leafhoppers. Leafhoppers are small, plant-feeding insects that are characterized by their ability to jump long distances.

Members of the Psorothoracinae subfamily are found in various regions of the world, with a significant diversity in species present in the Neotropical and Afrotropical realms. Their specific geographic distribution can vary widely depending on the genus and species.

The morphology of Psorothoracinae is typical of leafhoppers, featuring a wedge-shaped body, strong hind legs adapted for jumping, and piercing-sucking mouthparts used to feed on plant sap. Distinguishing features for classification within this subfamily often relate to the structure of their head, pronotum, tegmina (forewings), and male genitalia.

Ecologically, Psorothoracinae, like other leafhoppers, play a role in plant ecosystems. They are primarily phytophagous, feeding on the phloem or xylem of various plant species. Some species may be considered agricultural pests due to their feeding habits, while others may have more localized impacts or act as vectors for plant diseases. Research on the specific ecological roles and economic importance of many Psorothoracinae species is ongoing. The subfamily represents a portion of the vast and diverse leafhopper fauna, contributing to the overall biodiversity of hemipteran insects.
