Asaphus knyrkoi or plautini?

[Savvas]

Greetings everybody. I came across this Asaphus that is for sale. Seller states its Knyrkoi, I belive that its Plautini, am I right?

Asaphus plautini is a better match with small eyes and gently rounded facial sutures versus the relatively large eyes and sharply rounded sutures on Asaphus knyrkoi.

Thank you for the answer. I have this Asaphus for about a year in my collection and I always found it difficult to determine again the species. The seller stated Plautini, but now seeing the pictures seems like mine is an knyrkoi. What is your opinion? Or maybe an other species that eludes me?

They were switched at birth... ...it looks like a perfect match!

Thanks! Happy that I have at last figured that out.
