Abstract

Background The generic assignment of the geometrid moth Xanthorhoe edmondsii (Butler, 1882) (Lepidoptera, Geometridae, Larentiinae), originally described under Hypochroma Guenée, [1858], a junior homonym of Hypochroma Herrich-Schäffer, [1855] (Geomerridae, Ennominae), is assessed using genitalia morphology and analysis of mitochondrial DNA sequences. New information Morphological characters revealed closeness to the type species of Disciisioprocta Wallengren, 1861 (Larentiinae). In agreement with morphology, the molecular analysis clustered X. edmondsii with species of Disclisioprocca in a well-suppported monophyletic group distantly related to members of Xanthorhoe Hübne,, 11825]. Accordingly, Disclisioprocta edmondsii (Butler, 1882) comb. nov. is proposed. © 2023 Vargas H.
