The protologue (species description) of Phalaena perspicaria by Fabricius is in Entomologia systematica emandata et aucta. Supplementum Entomologiae Systematicae 1798; page 449,[3] where it says (in Latin):
P. pectinicornis alis angulatis obscure cinereis: puncto medio strigisque duabus punctorum nigrorum. Habitat Tranquebariae Dom. Lund.
Paullo maior Ph. tristriariae, tota obscure cinerea. Alae omnes supra puncto medio strigisque duabus posticis a punctis minutis, atris. Subtus pallidiores puncto medio strigisque unica atris.
At the Global Lepidoptera Names Index, P. perspicaria is suspected to be a senior synonym of Phalacra vidhisaria Walker;[4] in that case the name perspicaria is older and has a preference.
