Introduction

Ogyris arcana was originally described as a subspecies of O. otanes (C. & R. Felder, 1865) based on morphological characters. Schmidt et al. (2014) investigated the systematic relationships of the Ogyris idmo complex based on three genes (nuclear EF1a and two mtDNA, COI and cytB). They also investigated the evolution of myrmecophily and estimated divergence times in relation to arid Nullarbor Plain as a major biogeographical barrier dividing taxa of the mesic biome in south-eastern and south-western Australia. Beaver et al. (2023a) revised the taxonomy of the complex based on Schmidt's molecular data, adult morphology and other evidence, and recognised O. arcana M.R. Williams & Hay, 2001 as a species distinct from O. otanes (C. & R. Felder, 1865), with two subspecies: O. arcana arcana M.R. Williams & Hay, 2001, and O. arcana sublustris M.R. Williams & Hay, 2001.
