The genus Plesiochoffatia ("near Choffatia") was named by Hahn G. and Hahn R. in 1999. It has also been known as Parachoffatia ("beside Choffatia") Hahn & Hahn, 1998 (preoccupied).
Remains have been found in the Kimmeridgian (Upper Jurassic)-age strata of Guimarota, Portugal. Three species were described in the same study under the name of Parachoffatia; (P. peparethos, P. staphylos and P. thoas). As something else had already been given that name, the genus was renamed a year later.
