Identification

Members of Erythroneurini are leafhoppers in the Typhlocybinae. Identification to tribe level requires examination of male genitalia and other morphological characters used in the tribe's defining characteristics. Published keys exist for identification of males in several New World , including separate keys for North and South American Zyginama .

Taxonomic Complexity

The tribe exhibits substantial taxonomic complexity with extensive synonymies. For example, Eratoneura alone had 123 new synonyms recognized in a single revision, and Erythridula had 129 new synonyms recognized. This reflects historical difficulties in -level identification within the group.

Research Focus

Recent research has emphasized the southwestern Chinese karst regions as significant centers of diversity and for the tribe, with phylogeographic studies examining genetic differentiation in these areas.

Species Richness

Individual within the tribe are highly speciose: Erythroneura (54+ ), Erythridula (135+ species), Eratoneura (197+ species), Zyginama (71+ species), demonstrating the tribe's substantial diversity.
