Key to the males of Banyallarga

I provide this key for the convenience of readers who do not have ready access to the Internet. However, for ease of use and accuracy of identification, I recommend an interactive key, which will include any taxonomic changes subsequent to publication of this paper, maintained at <http://www.entomology.umn.edu/museum/projects>. Upon request, I can provide updated conventional or interactive keys on paper or CD­ROM.
