Remarks
This species is listed in The Owlet Moths of Ohio (2) as Idia species near aemula and is pictured as figure 2 on Plate IX. The text notes that the species has in the past been misidentified as Idia concisa (presumably refering to Idia concisa (Walker, 1860)). The species page at Moth Photographers Group assigns the name Idia concisa to this species, noting that the species has not yet been formally described.
"This species is related to Idia aemula but has a pale hindwing and a stronger median bar in the forewing. It was treated under the name concisa by Forbes (1954) and many subsequent authors, but is actually an un-described species. The holotype of Herminia concisa Walker is in the CNC and is a typical specimen of I. aemula." (1)
The examples of Idia “concisa” shown at BOLD are in the same BIN cluster here with Idia aemula, however, they are all close to each other in the same branch.
"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. 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)
