Abstrakt
A preliminary report about revision of the important agnostid genus Arthrorhachis Hawlw et Corda, 1847 is presented. The representatives of this genus belong to the latest agnostids (=agnostid trilobites).
Despite this, they are distributed globally and often relatively common in the Upper Ordovician associations. The generic name Arthrorhachis is supported instead of poorly defined Trinodus and the review of the species known from the Prague Basin, with pointed differences is done.
