Stictopelta is a of in the , Darninae. Members of this genus are found in the Americas, with documented in the southern United States, Mexico, and South America. The genus was established by Stål in 1869 and is characterized by distinctive pronotal modifications typical of membracid treehoppers. Species within this genus exhibit morphological variation that has led to taxonomic descriptions by multiple authors including Goding, Ball, and Fowler.
