Abstract
Trilobites of the Tourmakeady Limestone, County Mayo, western Ireland, comprise 23 species and genera. This fauna is an early example of the Illaenid-Cheirurid biofacies, being dominated by a few species of the families Illaenidae, Cheiruridae and Celmidae. It is basal Whiterockian (upper Arenig) in age. Several of the trilobites are early representatives of clades which achieved subsequent prominence. All but one of the species are represented by silicified material, and many are supplemented by crackout specimens. Four trilobite species have been previously named: Kawina divergens, Niobe ornata, Oopsites hibernicus and Illaenus weaveri, and are revised herein. One genus, Mayopyge (type species M. zapata sp. nov.), is new, as are the species Phaseolops ceryx, Protostygina coronula, Glaphurus crinitus, Dimeropyge? ericina, Celmus michaelmus, Agerina palabunda, Proscharyia platylimbata and Ceratocephalina ramskoeldi. The remaining species are described in open nomenclature.
