Nemoria bifilata planuscula

As a subspecies of Nemoria bifilata, planuscula would be distinguished from the nominate subspecies and other infraspecific taxa by subtle differences in wing pattern, size, or genitalia structure. The specific distinguishing characters from Ferguson’s original description are not widely reproduced in accessible literature. It would be separated from other Nemoria species by the white bar or line patterning characteristic of the N. bifilata group, in contrast to the more uniform green or differently patterned wings of congeners such as N. mimosaria or N. lixaria.

Known from Texas, United States. The distribution is more restricted than the full range of Nemoria bifilata, which extends across much of eastern and central North America.

• Nemoria bifilata bifilataThe nominate subspecies; planuscula differs in subtle morphological features as described by Ferguson, though specific distinguishing characters require examination of type material or original description.
• Nemoria lixariaAnother green Nemoria species with different wing patterning; N. bifilata planuscula shows the characteristic white bar or line that distinguishes the N. bifilata group.
• Nemoria mimosariaSimilar emerald green coloration but with more uniform or differently patterned wings; N. bifilata planuscula has distinctive white transverse markings.
