Coordinator notes: 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)
