Abstract

The systematics of the ten valid harpetid trilobite genera arereviewed. Seven are revised, using standard parsimony and three-itemanalysis. The monophyly of the Harpetidae is confirmed, and all ingroupgenera can be defended as monophyletic groups except for the non-monophyletic ScotolJarpes group. Emended diagnoses are provided for all thegenera within the family. The three subfamilies Dolichoharpinae,Eoharpetinae and Harpetinae are supressed within the Harpetidae. Thegenera AlIstraloharpes and Sinoharpes are placed in synonymy withDlIbhglasina. Thorslundops and Wegeiinia are placed in synonymy withHibbertia, and the subgenus FritclJaspis placed in synonymy with LiolJarpes.Reticuloharpes and HelioJwrpes are placed in synonymy with Harpes. TheHarpetidae, along with the Entomaspididae and Harpididae, is considered tobelong in the Harpetida, which is herein raised to ordinal rank within thesubclass Libristoma.
