Identification
Members of Davisonia can be distinguished from other Macrostelini by genitalic characters, particularly the structure of the male and the configuration of the female sternite VII. As with many leafhopper genera, definitive identification requires examination of internal genitalia under magnification. The genus shares the general Macrostelini characteristics of slender, elongate body form and relatively long wings that extend past the .
