Pseudo-curly top treehopper

Definition

A common name for Micrutalis malleifera, a treehopper species (family Membracidae) native to the southern United States and Central America. The common name distinguishes this species from the 'curly top' disease vector complex associated with other hemipterans, reflecting its superficial resemblance to beet leafhopper (Circulifer tenellus) and related vectors of the curly top virus while lacking the same pathogenic role. Adults exhibit the pronounced pronotal enlargement characteristic of Membracidae, with the extended pronotum forming a helmet-like structure over the body.

Etymology

From 'pseudo-' (Greek: false, resembling) + 'curly top,' referencing visual or ecological similarity to true curly-top disease vectors without actual equivalence; 'treehopper' from family Membracidae habit of perching on woody vegetation.

Example

Field surveys in Texas citrus groves record pseudo-curly top treehoppers on understory shrubs, where their presence requires differentiation from the beet leafhopper to assess actual curly top virus risk.

Synonyms

• Micrutalis malleifera

Related Terms

• treehopper
• Membracidae
• curly top virus

Usage Notes

The common name explicitly signals non-identity with true curly-top vectors; specialists prefer the scientific name Micrutalis malleifera to avoid confusion. The species does not transmit the curtovirus causing curly top disease. Family spelling in some sources appears as 'Memracidae' (erroneous) versus standard 'Membracidae'.
