Dicheros, Coryphocera, Hemicoryphocera

Dear colleagues and specialists,

I would like to ask if you have any Dicheros bicornis siamensis (Thailand), sumbawanus (Sumbawa Is.) or ornatus (Phillippines - except Palawan Is.). I am also looking for Dicheros (Coryphocera) and subgenus Hemicoryphocera. Currently I am conducting research on them so if you have any material for exchange or for sale please contact me.

Thank you.

Best regards,
Marek Duricek
