Naming
Jeremy Holloway (1993 [1994]), in his work on the Borneo ennomine moth fauna, illustrated Milionia zonea and wrote up an entry for it and a sister species, Milionia basalis, under the latter name, which at that time was considered the only species of the two, zonea being thought of either as a junior synonym (e.g. by Holloway) or as a subspecies (e.g. by Japanese taxonomists). In the updated Borneo moth book list (Holloway, 2011), Milionia zonea is listed as a valid species, agreeing with the review of the genus Milionia written by Prof. Inoue (2005), wherein zonea was promoted to (or removed from synonymy with basalis, depending upon one’s view) the rank of species.Distribution
Holloway (2011) gives the natural distribution of zonea as “N.E.Himalaya, Taiwan, Japan to Sundaland, Philippines” and of basalis as “Sundaland” (i.e. Borneo, Java, Sumatra and peninsular Malaya). The wide distribution of zonea already encompasses Hong Kong, and one should thus regard Hong Kong as being within the natural distribution of zonea.References:
