Palaeophylloxera nov. gen., The firstfossil specimen of the family Phylloxeridae (Hemiptera, Phylloxeroidea); Lower Miocene of Spain

A fossil alate aphid from the Lower Aragonian (Lower Miocene) deposits of Rubielos de Mora (Teruelprovince) in eastern Spain is described as Palaeophylloxera seilacheri nov. gen. and sp. It is the first fossil specimen described within the Family Phylloxeridae. The principal differences between this genus and other representatives of the Phylloxeridae (and also the extinct Elektraphididae) are the apparent presence of an oblique vein on the hind wing, the presence of distinctly visible transverse striae on antennal segment III, and the peculier venation on the fore wings.
