Agulla protomaculata
''Agulla protomaculata'' is an extinct species of snakefly in the raphidiid genus ''Agulla''. The species is solely known from the Middle Eocene, Lutetian stage, Parachute Member, part of the Green River Formation, in the Piceance Creek Basin and Uinta Basin, Garfield County, northwestern Colorado, USA.
==History and classification==
The species is known from a series of eighteen fossils, the holotype, three paratype females, ten male paratypes, and three paratypes of indeterminate sex. The holotype, number "USNM 31487", is a single female specimen consisting of part and counterpart fossils. All of the type specimens plus an additional male specimen tentatively identified as belonging to ''A. protomaculata'' are currently preserved in the Department of Paleobiology collections housed in the National Museum of Natural History, located in Washington, D.C., USA.〔 ''A. protomaculata'' 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 ''protomaculata'' as a combination of the Latin word "''protos''" meaning "first" and "''macula''" meaning "mark".〔 At least one other specimen is known and was figured in a 1995 publication by Dayvault ''et al'', however that specimen is though to still be in the private collection of William Hawes. At the time of the species description, ''Agulla protomaculata'' was the only member of the order Raphidioptera to be described from the Green River Formation.〔
