Talk:Mahathala

Mahathala is relatively overlooked in the literature and has not been revised bio-geographically at all. The last taxonomist to have lloked at the group with any detail being Talbot in 1942. The described taxa appear to have settled into 3 species, distributed from North to South, starting with gone in Mongolia, then with a ameria in an east-west belt from Assam to Taiwan including most of Burma and Thailand. The third species ariadeva is based in West Malaysia and Sumatra with a northward extension into Peninsular Thailand and southern Burma (sub-species burmana). The taxon javana Fruhstorfer, has usually been included as a subspecies of ameria but its extreme south-easterly location would suggest that it actually belongs to ariadeva. Thus I have used this distribution to assign javana to ariadeva pending further revision. Accassidy (talk) 19:26, 21 November 2011 (UTC)
