We have a type picture of Examnes genus here with fourth antennomera shorter.

Could your sp. belong to another tribe ? (Oemini ?)

The shape of the head is typical of the Xystrocerini.
It might be a Pelossus (ask to Sama how differentiate this genus from Xystrocerini... I have no idea).

I see only one species in Asia : Pelossus unicolor (Gressitt, 1951).

Thanks Francesco & Xavier, very interesting for me, but I miss the information about the genus Pelossus in my database, where is that published, maybe in Tavakilian (2013), I don't know this paper, do you have a pdf.
Acc to the description, it could be a male of P. unicolor, with remarkable features: tip of the antennal segment 3-5 thickened, in front of the fore coxae with a dull small spine. A bit strange for me this genus is congenerical with f.e. Lygrus or others.

In Titan database, it seems that nobody used Pelossus since the original description (Thomson, 1864). The last author, (Holzschuh, 1998) used Lygrus. I do not know who made the synonymy.

2 new Pelossus species are described in this paper:
Yokoi, Makihara and Noerdjito, 2106. Notes on the Genera Examnes and Pelossus (Coleoptera, Cerambycidae) in East Kalimantan, Indonesia.
