The genus lived during the middle of the Atdabanian or the early part of the Botomian stage,[2] which lasted from approximately 524 to 518.5 million years ago.

Lower Cambrian of Southern Morocco (Daguinaspis and Resserops-zone near Tazemmourt,[3] Amouslek and Ouijane[4]).

The Treatise[3] considers Resserops and Richterops subgenera of Perrector, which name was proposed by Hupé in the same publication, but appears above it and would have preference.

As with most early trilobites, Richterops has an almost flat exoskeleton, that is only thinly calcified, and has crescent-shaped eye ridges.

As a representative of the Redlichiina suborder, the headshield (or cephalon) has sutures where the exoskeleton ruptures to assist in moulting.
