Phylogenomic insights into helmet evolution in neotropical treehoppers (Hemiptera: Membracidae): Conserved morphological complexity across five subfamilies

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
Phylogenomic analyses of 2539 nuclear loci reveal robust relationships among major Membracidae lineages. Helmet shape complexity shows strong phylogenetic conservatism across genera, tribes and subfamilies. Pronotal modularity evolves across lineages, highlighting the developmental diversity of treehopper morphologies. Abstract We utilized genomic data
