Pallimnarchus pollens De Vis, 1886 (de facto?)
Last record is the Pleistocene, Late Pleistocene?
This species is only known from fossil remains of Pleistocene age. It may have persisted until less than 100,000ya, however this has not been confirmed. There is no reason why it shouldn't have done so, and absence of fossil remains is not necessarily evidence of absence. It's listing here is therefore tentative.
