21 mm,
Borikham, Bolikhamxai Prov. Laos, 27.4.2013.
Un Noserius peut-être (et quelle tribu ? Xystrocerini comme dans biolib ou Oemini comme dans Titan ??), mais la liste est courte et il y a peu d'espèces pour la zone du Laos.
Ou un autre genre ? |

| I need to check material in my collection but this reminds me of Examnes elongatithorax Hayashi (Callidiopini) which was described from W. Malaysia but is also common in Northern Borneo. |

I find no mention of this species in Laos (neither in Thailand, Myanmar, etc); I see at least 2 differences between Hayashi's description and my specimen : "...antennae in male fairly longer than body, surpassing elytral apices by the apex of eighth joint, ..." It is the seventh for my species.
"Scutellum triangular..." -> It's rather a square for my specimen.
Could you make a picture from Borneo specimen, please ? |

I find Hayashi's descriptions to be a little weak, however... your specimen from Laos is not E. elongatithorax... but it is similar, especially the legs, which have the same markings.
As the name implies, "elongatithorax" has a slightly more elongated pronotum, and is a little smaller. It's antennae are just slightly longer. I don't have a photograph of E. elongatithorax at this time.

Cher Xavier, dans le but d’identifier la tribu, les Callidiopini sont un des seuls tribus (avec les Elaphidiini) caractérisés par les cavités cotiloides médianes ouvertes.
Portant il me semble que cette bête, avec l'espace inter-antennaire ainsi développé ne me semble pas appartenir aux Callidiopini, mais plutôt aux Xystrocerini ou aux Hesperophanini.
Cette deuxième tribu diffère de la première pour la ligule membraneuse ou lieu que cornée... caractère pas de tout facile á identifier...

En revenant sur ce sujet (j'ai en marre d'être polémique, mais il faut vraiment arrêter de déconner). 
C'est le même discours de Lamiini-Monochamini, ou Saperdinini-Phytoecini-Obereini.
It is not possible to accept the division of these tribes, basing on articles that confront the 2-3 genera known by such authors and ignore the hundreds remaining.
This is not my opinion, it is a fact.
Or these authors provide characters valid for all genera and complete tested lists of genera for each "new" tribe, or these "papers" are garbage.
According to Martins, Xystrocerini differ from Oemeni in having a spine on the scape... but are you joking?
And Listrocerum, which has that spine, why belongs to Oemini????
And so on...

This is the holotype of Examnes elongatithorax Hayashi, 1979. |

And the specimen might be female of it in my collection. |

Thank you very much Beckey!
The pattern is singularly analogue, but the pronotum looks really different.
According to me, it belongs to Hesperophanini, maybe Gnatholea.
Here Gnatholea simplex Gahan, 1890. |

Bonjour a tous
La bête de Xavier est d’un genre différent, on peut voir au niveau du 4 ème article des antennes une différence de taille.

Bonjour,
D'accord avec Francesco pour le thorax, beaucoup plus arrondi; et avec Gérard pour les antennes.
J'ai pensé aussi à un Hesperophanes, mais je ne vois toujours pas de quelle espèce il pourrait s'agir. |

Hi,
Following your idea, Beckey, there are not so much choices.
Here the original description of Nortia dembickyi Holzschuh, 1995, ...but I don't understand German langage  . Is anybody able to translate ?
I add my picture to the text for helping to compare. Holzschuh's picture is in black and white, and unclear for seing bicolor legs, but they seems bicolor.
