Idaea egenaria (Walker, 1861)
See notes in observation no 273057
GI: This is I gemmaria and not I egenaria. Going by the references in 273057, both the iNaturalist image and the description in the OD or the image on MOB does not match this accurately enough to be identified as I egenaria. I do agree that the slight twist in the band is typical of egenaria and I too had identified the KMTR moth as I egenaria which matched egenaria image on MOB quite a bit; but Dieter disagreed after comparing it with the specimens from the museum. I will try and share the discussion we had on this as soon as i can lay my hands on it.
This image as well as the one in 273057 match quite closely with what we have reported as I gemmaria in out paper on KMTR.
Hence to me this is Idaea gemmaria not egenaria
SS: Frankly, based on images on iNaturalist and the plate in Seitz, I would agree that this is egenaria and not gemmaria. However, Prout, in Sietz, himself mentions that gemmaria is close to egenaria, and perhaps a form. I find that the straight band on FW in egenaria, (all images of gemmaria on MOI have broad band on FW, curved inwardly) aureole on FW absent or obsolete in egenaria (more often present in gemmaria, see all images on MOI). Given, this I would identify both species provisionally, and publish the egenaria from NE India.
