Bonjour à tous,
Ce couple de cerambycinae de Borneo (Trus-Madi / Sabah) 19 / 17 mm me pose problème.. il ressemble au genre Zatrephus, mais la taille est plus modeste et chez Zatrephus les articles 3 à 5 des antennes sont bulbeux et les derniers articles n'ont pas de dent apicale.
Merci par avance si vous avez une idée du genre. |

| Zatrephus inscitus Pascoe, 1857 pourrait très bien coller. |

Merci Gérard, effectivement j'ai retrouvé un ancien post traitant de la même espèce.
Les articles antennaires correspondent et je pense être en présence de 2 femelles. |

I believe you have an Imbrius sp.
I'll post Z. inscitus later for reference. Z. inscitus is never this small, anyway. |

| I agree, elytra are too long, no ? |

I think there are two different species in the photograph. The sculpturing of the pronotum appears to be different.
I think the specimen on the left is Imbrius uniformis Holzschuh, 2010 and the one on the right is I. simulator Holzschuh, 2005.
A close-up shot of their pronotums would be needed to verify this. When pubescence gets rubbed off of the elytra or pronotum, or the color of the photograph is a bit unnatural, it is very difficult to be sure. |

OK, they both seem to be the same species: I. uniformis
The pronotal sculpturing appears to me to be similar, although the pubescence has been rubbed a little on one of them.
