This is an Ibidionini, excuse me... now Neoibidionini, or possibly Hexoplonini.
With luck, you can match it to a photograph on the Western Hemisphere Cerambycidae web site or perhaps the French Guiana web site (via www.golofa.fr). Many species are only known from a few specimens, so the photographs may not be very good. There are an enormous number of similar species.

It is Hexocycnidolon unoculum (Bates, 1870) of the tribe Hexoplonini Martins, 2006.

The tribe Ibidionini, disappeared due a taxonomic mistake, will be restored in a next paper.
Neobidionini will be considered as a synonym (unnecessary replacement name).

Dear Dan and Francesco, thank you for your ID!
But I don't think it is Hexocycnidolon unoculum (Bates, 1870) based on the holotype in Larry's database:
https://apps2.cdfa.ca.gov/publicApps/plant/bycidDB/wdetails.asp?id=2828&w=n

Because the shape of apex of scape and the shape of femora are different from Hexocycnidolon unoculum (Bates, 1870).

You are right, though the last linked pictured was wrongly identified (it is a Cycnidolon)

It might be Cycnidolon approximatum (White, 1855), Ibidionini.
