Phylogenetic relationships among the genera of Apochrysinae are examined. Exemplars from all 13 previously defined genera of the subfamily are compared with outgroups from the Nothochrysinae (Nothochrysa McLachlan) and Chrysopinae (Italochrysa Principi) in a parsimony analysis of 78 character states across 39 adult morphological characters. The analysis resulted in three most parsimonious trees with a length of 70 steps. The Apochrysinae are confirmed as monophyletic, with the enigmatic genus Nothancyla as the sister to the rest of the subfamily. The phylogenetic relationships among the genera of Apochrysinae are discussed, as are primitive and derived venational characters and wing vein reticulation in apochrysine wings. Six valid genera are recognized in light of the analysis: Apochrysa Schneider (Anapochrysa Kimmins, Lauraya Winterton, Nacaura Navás, Oligochrysa Esben-Petersen and Synthochrysa Needham, syns. nov.), Domenechus Navás, Joguina Navás (Lainius Navás syn. nov.), Loyola Navás (Claverina Navás syn. nov.), Nobilinus Navás and Nothancyla Navás. Valid genera are rediagnosed in a revised classification. A new key to genera and lists of included species are presented.
