Identification
Distinguished from other delphacid by combinations of genitalic structures, particularly in the male and female ovipositor. The subfamily is characterized by specific wing venation patterns and capsule that separate it from Delphacinae and other subfamilies. Reliable identification requires examination of microscopic features.
