It was described by Chlupac in 1972, and the type species is Boeckops boecki, which was originally described as Phacops boecki by Hawle and Corda in 1847.

Lane in 1988, and the type species is Distyrax peeli. It also contains the species, Distyrax cooperi. The type locality was the Odins Fjord Formation.

Arcticalymene is a genus of trilobites found in Silurian-aged marine strata of Arctic Canada and Central Victoria, Australia. The Canadian species are named after each of the Sex Pistols: A. cooki, A. jonesi, A. matlocki, A. rotteni and A. viciousi, all named by Adrain and Edgecombe in 1997.
Bumastus is an extinct genus of corynexochid trilobites which existed from the Early Ordovician period to the Late Silurian period. They were relatively large trilobites, reaching a length of 6 in (15 cm). They were distinctive for their highly globular, smooth-surfaced exoskeleton. They possessed well-developed, large compound eyes and were believed to have dwelled in shallow-water sediments in life.
Mackenziurus is a genus of phacopid trilobites from the Silurian containing several species, including four named after members of the American punk band the Ramones.
