| With Breuning's key (Longicornes du Laos, 1970), I find also Palimna annulata (Olivier, 1792) with lobe-like process on 7 antennomere. |

Dear Max,
first, please forget Breuning for identifications completely, sometimes you have really success but the variance is at least 100% 
Your first spms from Vietnam belongs to P. similis Gressitt, 1940 (I think recently a ssp. to palimnoides) and the 2nd one with a processus at the 7th antennomere is P. annulata (Oliver, 1792) so far from the pictures. |

Thank for your opinion, Xaurus!
I did not use Breuning, I did not determinate these beetles in this case.. This is a difficult group, but I do not know the tropical fauna and do the suggestions merely (in habitus).
Xavier`s beetle from Laos (P. palimnoides similis) does not look like my from Vietnam. The limits of variability are unknown for me, but the difference in length of the antennas and particularity of tracery.. it seems important to me. |

| The variability of patterns is important for this group, as I can see on my series of different species. |
