genitalia: Apophyses posteriores very long, reaching proximad nearly to the base of the abdomen.

Diagnosis:

P. aurea is the only known species of the genus so far. For features distinguishing Palaeolepidopterix Kozlov, 1989 from other genera of the Eolepidopterigidae, see there.

Phylogeny: The assignment of the impression to Lepidoptera is demonstrated by the most probable presence of scales on the forewing. The long apophyses posteriores and the well developed pronotum indicate an assignment of P. aurea to the family Eolepidopterigidae, but we do neither know of any apomorphies for that family, nor for P. aurea to prove that assignment.

Worth knowing:

The fossil has been assigned to the Upper Jurassic, between Oxfordian and Kimmeridgian (Kozlov 1989). This implicates an age of 161.2 - 150.8 Ma.
