Archivesica strigarum was initially described based on only a few specimens from the Middle Miocene Sasso delle Streghe and Deruta localities (Kiel & Taviani 2017), but our new collections indicate that this species is quite common in the Middle Miocene seep deposits in Italy. The new specimens illustrated here show the previously only poorly known external surface and provide a better view on the hinge.
Upper Oligocene (upper Chattian) to Middle Miocene, northern Italy.
