Similar Species: Idia aemula typically lacks the combination of forewing with a strongly defined dark medial bar and a contrastingly paler hindwing. Note: "Idia aemula is probably a complex of 5-10 species, one of which is what is called concisa.” - Hugh McGuinness (pers. comm. 1/10/2018). This seems supported by DNA barcoding. However, if ‘concisa’ is not aemula, then it’s probably at least two good species. The examples of Idia 'concisa' shown at BOLD are in the same BIN cluster, BOLD:AAA2229, with I. aemula. They form a single branch composed of two smaller branches in the barcode tree separate from other branches. Based on barcode, having a forewing with dark medial bar and/or a contrastingly pale hind wind wing will separate most specimens but it is far from conclusive. - Steve Nanz (4/11/2020) Pinned specimens of related species. (Hint: select View by Region on the related species page.) Synonymy: concisa of authors; (not Walker, 1860) (Herminia) MISAPPL. Taxonomic Notes: Idia concisa of authors; (not Walker, 1860), awaits new species description, Lafontaine & Schmidt (2010), ZooKeys, 40: 1-239. The species Idia concisa Walker, 1860 is a synonym of Idia aemula Hübner, 1814 (Lafontaine & Schmidt 2010).
