| Summary: | New specimens of aglaspidid arthropods, mainly from the Upper Cambrian St. Lawrence Formation of Wisconsin (Upper Dikelocephalus Zone), show that appendages previously assigned to the genotype Aglaspis barrandei actual belong to a new genus and species Flobertia kochi. Chraspedops fragilis is transferred to a new genus Tuboculops. The generic attribution of Aglaspis dorsetensis and Aglaspis franconensis is queried. The distinction at species level is queried for Setaspis spinulosus and S. regularis and also for Aglaspoides sculptilis and A. semicircularis, although no formal changes are recommended. Aglaspis simplex is transferred to Glypharthrus simplex and Glypharthrus deadwoodensis is synonymized with Glypharthrus vulpes. -from Author |
