Remarks. This species is very similar to M. brunnescens established by Anufriev (1968), but differs from the latter by the 2nd tergal apodeme with a median projection; 2nd sternal apodemes with posterior lobes narrow and 2.5 times as long as basal width. However, the latter with the characters of 2nd tergal apodeme without a median projection and 2nd sternal apodemes with posterior lobes broad and 1.5 times as long as basal width (Kwon, 1988).

Etymology. The specific epithet “ brunneus ” refers to the forewing having brown longitudinal bands.
