I found one male of Purpuricenus sanguinolentus with the extreme form of a colour pattern (see photo below). Probably the extreme forms of P. malaccensis can be even darker, as their yellow bands should be mostly narrower.
By the way, regarding the shapes of puncture areas in pronotum, some males look like transition forms between the two species. Are these really good species?

The difference in pronotal structure can be observed only in males. Females are more difficult to understand as usual.
According to Gahan, 1906 P. malaccensis should have in general yellow bands narrower than those in P.sanguinolentus. The colour pattern in Sergi's beetle is surprisingly similar to that in P. quadrinotatus. I have a big series of the two former species, shall have a look whether there is any specimen similar to Sergi's. |

You have to observe the pronotal structure. Reading this post could help you ? |

Coming from Laos, your specimen is for me probably P. malaccensis female. Purpuricenus species vary a lot. I can't say more...

Yes, but my insect is different from both species!!! undoubtedly I believe that is a Purpuricenus  |

OK, thanks. Female antenna are shorter than P. malaccensis |

Can you see the following web: http://www.biolib.cz/en/taxonimage/id218535/ |

Interesting ! If you can share a picture of it... |

I believe that there are specimens of P. quadrinotatus from Indonesia and perhaps Malaysia... |

Well, Purpuricenus quadrinotatus White is a species from Australia...No way to find it in Laos, no ?
You never check with Titan database ? It's the most important work for Longhorn beetles bibliography. |

I thought in a form of Purpuricenus quadrinotatus.... |

It should be a female of Purpuricenus malaccensis (Lacordaire, 1869) with reduced macules. |
