Description of adults: Original description from Kozlov, 1989: "Labial palps long, protruding from under head at distance equal to diameter of eye. Ocelli located behind compound eyes. Pronotum somewhat smaller than head, 1.3 times longer than diameter of eye. Wings elongate and oval, ratio of width of forewing to its length 0.3; apex of forewing somewhat shifted foreward from midline. Jugum well developed, bearing cluster of long hairs on inner margin. On forewings, forewings, [sic!] R1 forked, R5 extending to apex of wing. On female genitalia, hind apophyses reaching to base of abdomen." Mouthparts and legs are not preserved.


The genus is known only from the type specimen of Palaeolepidopterix aurea Kozlov, 1989, which has been found in sediments in Kazakhstan, Chimkent Oblast, Chayan district, locality Aulye close to the village of Mikhaylovka. These sediments are attributed to the Upper Jurasic, Oxfordian-Kimmeridgian, Karabastau series (Kozlov, 1989). The age of the remnants is therefore estimated to be 161.2 - 150.8 Ma.


Nothing is known about the biology of the fossil species.

genitalia. Last segments of the abdomen seem to form a short ovipositor; apophyses posteriores extremely long, reaching nearly to the base of the abdomen.

Following Kozlov (1989), Palaeolepidopterix differs from Eolepidopterix Rasnitsyn, 1983 in having a larger pronotum and longer apohyses on the female genitalia. In Daiopterix Skalski, 1984, Sc and R1 reach the forewing margin more distally. Furthermore, Palaeolepidopterix has a well-developed jugum with a cluster of hairs.

Phylogeny (Kozlov, 1989): "Assignment of Palaeolepidopterix to Lepidoptera is confirmed by a relatively well-preserved monotone bronze, shiny metallic, scaly covering of the forewings, and also a well-developed jugum bearing a cluster of hairs. Among recent Lepidoptera, a similar jugum structure is observed in swifts. The large dimensions of the pronotum make it possible to assign the described genus to the family Eolepidopterigidae; the long labial palps bring it close to Eolepidopterix A. Rasn.".
