Bolboparia is an extinct genus of eodiscinid agnostid trilobites. It lived during the late Lower Cambrian in what today Canada and the United States.
Bolboparia is most closely related to Acidiscus and slightly more distantly to Stigmadiscus.
Like all Agnostida, Bolboparia is diminutive and the headshield (or cephalon) and tailshield (or pygidium) are of approximately the same size (or isopygous) and outline. Like all Weymouthiidae, Bolboparia lacks eyes and rupture lines (or sutures). The short, downsloping glabella and the bulging cheeks give it a very peculiar aspect.
