Comments. Analysis of our imaginal material showed that the D. khumbugelida male from the type locality in Nepal differs from males of other populations. Therefore , we decided to provide separate descriptions for these males. It is possible that in the future, after obtaining barcoding data for this species from Nepal, it will turn out that these are different species. See more detail in the Remarks .
