Identification
"Closely related to Gypona. Vertex broad, flattened, and with the margin acutely angled with front and foliaceous. Pronotum broad, transverse, striated. Elytra rather long and narrow with many irregular reticulations; the apical portion especially is supplied with irregular reticulations." —DeLong (1942)
While females usually do not have distinct pregenital sternites, it is a good practice to take ventral photos of any leafhopper for identification. Very few species are readily identifiable based on external characters. There may be a number of cryptic species indistinguishable by male genitalia. Collecting is crucial for positive ID.
