Posted - 20/02/2018 : 19:12:21 Thank you Dan for your help. This one from Tawau looks indeed like pubiventre. It has some pubescence underneath but I compared with Holzschuh's paratypes and I see these have not a flat elytral disc as we can see on pubiventre or Sumatra's carinatum. Antennae first segments are also different. I agree that these species are already so difficult to do in hand, so only a photograph is not enough. Anyway this step will make me look closer. Thanks also for your other Euryarthrum IDs.

Some of these species are difficult to do even if you have them in hand. By photograph, it is not reliable....
