A pretty small Trachyderini, from Mexico also (16mm).
It makes me think of Parathestesis convergens, but I am not satisfied with this, the legs are too short and show a different coloration.
Or do we have some Parevander or Paroxoplus variation?

No, it isn't.
According to me, it is a Lamiine of the tribe Hemilophini. It is necessary to check all genera, since no key about them exists.

Beh...the shape of the median tibiae is fairly typical... nonetheless, I have checked all Hemilophini and I could not find this species.

I did the same. But none of the photos did fit with this beetle.

So there is only one candidate more: Mecas sericeus.

Yep! That's it! Thank you!
Monné & Hovore list the genus Mecas (with it's subgenera) among the Phytoeciini Tribe.

I've seen... I wonder why they did not select Gleneini: the lateral ridge seems well evident!
