Hi Olivier, I checked P. dalbergicola after reading your post. The one I posted may be another species. Gressitt described the antenna of P. dalbergicola as "antennae tawny from base to middle of third segment, thence blackish to middle of sixth segment, then white to middle of eighth segment, and blackish on remainder". Antenna of the one I posted with the 6th segment totaly black and the base of the 7th black. The black patch of elytra after the posterial white band seems not presenting on P. dalbergicola. I am not sure if it is sexual biomorphism. I am also not sure that the beetle of my photo is a male and if biomorphism is common in the genus of Pterolophia .

Maybe Pterolophia (Mirmoron) dalbergicola Gressitt, 1951 have similar white patches on antenna. Do you can check it Nalslan?
China: Pterolophia sp.
