Dr. David Lees from the Department of Zoology of the University of Cambridge, United Kingdom, has helped me identifying this moth.
David Lees has extensive field research experience in Madagascar and is considered the authority on Madagascar butterflies and moths.
I was very fortunate to meet him in Madagascar in January 2014 at the time I was visiting.
