Ptychopariina is an extinct suborder of trilobites of the order Ptychopariida. [1] Also known as the primitive Ptychopariida, they are a notably wide and varied taxon. [2] Some of the representative genera include Elrathia, Densonella, Norwoodia, Tricrepicephalus, Conocoryphe, and Modocia. [2]
Specialization is common in the Ptychopariina, which has made it difficult for authors to develop a single type that can distinguish Ptychopariina from other clades. The thorax tends to be relatively long, with the pygidium generally smaller in size than the thorax. [2]
