Unfortunately many important species share similar genitalic
structures and this has forced workers to continue relying on less dependable characters that often are intraspecifically variable and subject to phenotypic plasticity (Pinto et al.

In addition, differences in genitalia are now recognized as one of the most important species-isolating mechanisms in cicadas, with genitalic
differences being the only means to separate otherwise morphologically similar species.
