Micrutalis malleifera

Definition

A species of treehopper (Hemiptera: Membracidae) native to the southern United States and Central America, commonly known as the pseudo-curly top treehopper. Adults exhibit the enlarged pronotum characteristic of the family, which extends over the body and may aid in crypsis among foliage. The species is of agricultural interest due to its association with solanaceous crops and potential role in plant disease transmission.

Etymology

Latin: malleifera, 'hammer-bearing', likely referring to the shape of the pronotal process.

Example

Field surveys in Texas citrus groves recorded Micrutalis malleifera aggregating on young shoots, where nymphs and adults fed phloem sap and produced honeydew that supported sooty mold growth.

Usage Notes

Distinguished from the true curly top leafhopper (Circulifer tenellus, Cicadellidae), which transmits Beet curly top virus; the common name 'pseudo-curly top' reflects this morphological mimicry or ecological overlap without implying shared vector capacity. Fowler (1895) described the species based on Central American material.
