Ball, 1931
leafhopper
Species Guides
38Scaphytopius is a large of leafhoppers ( Cicadellidae) containing at least 170 described . The genus was established by Ball in 1931 and is classified in the Deltocephalinae and tribe Scaphytopiini. Multiple species have been documented as of plant , including phytoplasmas affecting citrus and peach. The subgenus Cloanthanus, revised by Hepner in 1947, is poorly represented in Canada compared to more southerly distributions in North America.

Identification
Identification relies heavily on male genitalia structures, particularly the shape of the paraphyses and . External characters such as color, markings, and body structure are often unreliable due to intraspecific variation. The subgenus Cloanthanus can be distinguished using genitalic characters, though some variation in curvature of paraphyses occurs. -level keys for regional faunas exist, including for Canadian species.

Distribution
North America, with majority of having southerly distributions; some species such as Scaphytopius (Cloanthanus) acutus have nationwide distribution in North America. Canadian fauna is relatively depauperate compared to southern regions.
