Mimegralla is a large genus containing more than 60 species in the Oriental and Australasian region. However, the concept of this genus has been confusing since most species were described without detailed definition of the genus, and as a result it is highly possible that multiple species groups have been collectively referred as Mimegralla . For example, formal Afrotropical Mimegralla mainly described by Verbeke (1951) are now believed to belong in Hybobata Enderlein ( Marshall 2017 ) . Since this genus is in need of a thorough revision ( McAlpine 1998 , Marshall 2017 , 2019 ), effectively redefining this genus and providing diagnosis clearly exceeds the scope of this paper. Consequently, we restrict the diagnosis for the single species treated in this paper, and deposit the specimen in National Institute of Biological Resources, Korea (NIBR) for the future.
