You will be fed up with mine & Kurt's Maliau Basin species soon! I wish this had settled on a better background, but beggars can't be choosers! One of these days I will post something you find interesting to reward you for all your help, I hope!
You did not write me the size, but I guess a very small cerambycid. It seems to me a representative of Pteropliini (Similosodus or Mispila)... very difficult to identify it without having the specimens under a microscope... unless having this species...
