Diagnosis

Reference	Diagnosis
F. A. Sundberg 1994	Dorypygidae with cranidium with medially inflated to subquadrate glabellae, effaced to nearly effaced lateral glabellar furrows; fixigenae convex, slightly downsloping. Pygidium with well-defined axis generally extend- ing to border, 3-5 ring furrows; pleural fields crossed by 3-5 generally deep pleural furrows; interpleural furrows shallow, exsagittal width of anterior pleu- ral bands increases laterally; width of posterior pleural bands uniform; border moderately well defined, generally 3-4 pairs of spines of equal length, a posterior pair of greater length, and most pos- terior pair very short, unevenly spaced along mar- gin.
