[1] In the same year, Lieberman & Kloc[2] erected Modellops and Philipsmithiana but those genera are regarded as subjective synonyms of Hollardops.

The 10-segmented thoracic condition of Hollardops is a rare feature among acastid trilobites that almost always have 11 thorax segments.

Van Viersen & Kloc construed Hollardops as a scavenger or predator with well-developed eyes, that used its shovel-like cephalon to plough the top layers of the sediment in search of food.

Hollardops had small pits horizontally along the fringe of the exoskeleton; these are believed to have housed setae that allowed the trilobite to closely monitor its surroundings.

Hollardops has 10 thoracic segments and also has 5 pairs of pleural lappets or spines projecting from the pygidium.
