We present a phylogenetic analysis that includes all known species of Agathemera, using as outgroup four species of the genera Heteronemia, Spinonemia, Monticomorpha, and Anisomorpha. Phylogenetic inference was based on three genes, 16S, COI (mitochondrial markers) and H3 (nuclear marker), based on the maximum‐parsimony, maximum‐likelihood and Bayesian inference methods. Our results show that the genus Agathemera is monophyletic; six of its eight species showed phylogenetic support, while the group A. claraziana + A. millepunctata was not resolved. The resulting topology shows two major clades, the first with A. maculafulgens, A. luteola, A. crassa, A. millepunctata, and A. claraziana, and the second including A. grylloidea, A. mesoauriculae, and A. elegans. Species of the first clade have large mesonotal processes and are found mainly east of the Andes, except for A. crassa. Members of the second clade have small or absent mesonotal processes and are distributed mainly to the west of the Andes. © 2012 The Linnean Society of London, Zoological Journal of the Linnean Society, 2012, 165, 63–72.
