I have lost your topic Andre... but I remember that something did not work. Aurivillius described cordatus as a variety from Sumatra, and Breuning deemed it as such.

But both specimens posted in this forum correspond to the typical form:
I do not know if this form may be considered as a subspecies; however, it is not present in Thailand (neue Meldung? ).
