In male genitalia, this species is similar to G. albidusa sp. nov., but the costal arm longer than valva and middle of it with a spinelike process, while G. albidusa has the costal arm shorter than valva and middle of it without the spine-like process.
Etymology. The name is derived from the Latin “ di ” and “ stigma ”, corresponding to the 2 black spots on marginal area of forewing.
