Hollardops mesocristata?

[Ludwigia]

I just acquired this trilobite over an internet auction house. The seller could give me absolutely no information about it, but I'm pretty sure that this is a Hollardops mesocristata from the late Emsian, Middle Devon. I would just like to ask the experts here on this subject if I am correct in my assumption and if they perhaps might be able to suggest its provenance. It's 6cm. long.

Looks like a good match.  Here are the figures from Morzadec 2001:

Thanks for the quick reply, Scott

Another taxonomic update to report: Hollardops mesocristatus replaces H. mesocristata 

 

"According to the International Code of Zoological Nomenclature (article 30.1.4.3) a compound genus-group name ending in “-ops” is to be treated as masculine, regardless of its derivation or of its treatment by its author. Consequently, we change the names Quadrops flexuosa and Hollardops mesocristata into Q. flexuosus and H. mesocristatus, respectively."
