Californian Prong-gilled Mayfly (Paraleptophlebia californica 

This species was described in 1934.  

The Californian Prong-gilled Mayfly was endemic to California, USA, where it was originally found in the Waddell Creek in Santa Cruz County. It was subsequently (in 1968) found near the Anderson Fork, a stream north of the city of Chico in Butte County.  

The species was never found since and is considered most likely extinct.
