Oklahoma Trilobite

[Peat Burns]

This trilobite is labelled as Viaphacops from the Bois D'Arc Fm., Devonian, Oklahoma.  Can anyone confirm and perhaps assign a specific epithet?  Scale in mm.

This one is Paciphacops campbelli that has 3 or occasionally 4 lenses per lens file.

And according to @GerryK via FB:

 

"Viaphacops has been reported from Oklahoma and some dealers have been selling incorrectly Phacopid specimens from Oklahoma as Viaphacops.

I have not seen a real Viaphacops from Oklahoma."
