Além de minuciosa análise dos caracteres genéricos são descritas quatro espécies novas e fêmeas atê então desconhecidas de cinco espécies e redescritas as espécies restantes, na maioria dos casos, baseadas nos tipos. Duas espécies não foram vistas pelo autor, Oxyagrion cardinale e Oxyagrion brucki. o macho de Oxyagrion cardinale e as fêmeas de Oxyagrion brucki e Oxyagrion haematinum ainda são desconhecidas.
