Dear Mr. Garg,
Actually, expertshave merged arunensis and pradhanii to bicornuta, and
discolor to kathmanduensis but our expert Mr. Gogoi has already published book
separating all these species as individual sp.. Accordingly, POWO has already
separated discolor and kathmanduensis in their site. I hope they shall be separating
these three sp. as well in due course of time.
