Material examined ITALY – Emilia-Romagna • 1 spec. ; Castel di Casio ; MGGC 22322 • 2 specs ; Castillon dei Pepoli ; MGGC 22323 (L = 79.8, H = 39.8 mm ) • 13 specs ; Caselle A ; NRM Mo 204841 (L = 73.2, H = 38.8, W = 27.8 mm ), NRM Mo 204842 , NRM Mo 204843 • 13 specs ; Casola ; MGGC 22326 (L = 41.5, H = 23.5, W = 13.3), MGGC 22325 (L = 45.0, H = 27.0, W = 16.1), MGGC 22324 (L = 48.6, H = 27.4 mm ) • 1 spec. ; Guzzano ; MGGC 22328 . Remarks 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. Stratigraphic and geographic range Upper Oligocene (upper Chattian) to Middle Miocene, northern Italy .
