Placer’s Prong-gilled Mayfly (Paraleptophlebia placeri)
This species was described in 1939.
The species appears to have been quite widespread, it was originally found in at least three sites: Amador Creek, Dry Creek, Grass Valley Creek, and Jackson Creek in the Amador County, but was also found in other areas including Alameda County, El Dorado County, Marin County, Mariposa County, and Shasta County in California, Benton County, Josephine County, Lincoln County, and Union County in Oregon, as well as Grays Harbor County in Washington.
The youngest specimens date to 1977, younger collections are not known, and it is possible that this species is already extinct.
