Identification

Liviinae can be distinguished from Euphyllurinae by wing venation patterns and plant associations. Members of Liviinae generally have more reduced wing venation and are associated with dicotyledonous host plants, whereas Euphyllurinae are primarily associated with monocots, particularly palms. Specific identification to or species requires examination of genitalia and other minute morphological features.

Taxonomic note

The Liviidae was re-established following molecular and morphological studies that separated it from the historically broader family Psyllidae. Liviinae represents one of two within this redefined family.
