Subclass Heterodonta Neumayr, 1884 Family Vesicomyidae Dall and Simpson, 1901 Genus Pleurophopsis Van Winkle, 1919

Type species: Pleurophopsis unioides Van Winkle, 1919 , by monotypy; middle Miocene , Trinidad .

Note: The Treatise ( Keen 1969) cited the author of Pleurophopsis as “Palmer, 1919”, because Katherine Van Winkle (1895–1982) changed her name to Palmer when she married Ephraim Laurence Palmer (1888–1970), Cornell University professor of Nature Study in 1921. However, her account on the fossils from Trinidad that included the introduction of Pleurophopsis was published two years earlier under her maiden name Van Winkle.
