Dr. David Lees from the Department of Zoology of the University of Cambridge, United Kingdom, who I met in Madagascar in January 2014 and who has extensive field research experience in Madagascar and is considered the Madagascar butterfly expert, helped me identifying this species. 
Dr. David Lees informed me that this Pterophorinae species in the family Pterophoridae seems referable to Crassuncus pseudolaudatus (the holotype male was also described from Anjozorobe, and at that time only one specimen was known).
