The species is solely known from the Middle Miocene, late Bartovian stage, Pacific Union Site in the Stewart Valley Group, Mineral County, Nevada. ==History and classification== ''Agulla mineralensis'' is known only from one fossil, the holotype, specimen number 539. The specimen is composed of a complete specimen of an isolated hind-wing which is preserved as a compression fossil in sedimentary paper shale. The fossil was recovered from outcrops of the Stewart Valley group shales at the Pacific Union site, BLM locality #26-30-09-335, in Mineral County, Nevada, USA.〔 ''A. mineralensis'' was first studied by Michael S. Engel of the University of Kansas, Lawrence, Kansas, USA. His 2009 type description of the new species was published in the journal ''Transactions of the Kansas Academy of Science''.〔 Engel coined the specific epithet ''mineralensis'' in honor of Mineral County, where the species was found.〔 At the time of the species description, ''Agulla mineralensis'' was the only member of the order Raphidioptera to be found in Neogene aged fossil deposits in North America.〔
