A new genus and species of dustywing is described and figured from Baltic amber. Geroconiocompsa ostara, new genus and species, is closely allied to Archiconiocompsa Enderlein (Coniopterygidae: Aleuropteryginae), itself known from a single Eocene amber species (Archiconiocompsa prisca Enderlein) and tentatively assigned to the Coniocompsini. The new genus shares with Archiconiocompsa the deeply forked forewing M, Cu forked near the wing base, two crossveins between Cu and A₁, sc-r present in the forewing, Sc₂ not joining Sc₁ in the hind wing, and crossveins present between Cu₁ and Cu₂, and A₁ and A₂ in the hind wing, but has a more primitive form of venation in the connection of the posterior branch of Rs (R_{4 5}) to the anterior branch of M (M_{1 2}), the shorter distal abscissa of Sc₁, and the hind wing r₁ -rs distad the Rs fork, features reminiscent of many Aleuropterygini. The new genus further bridges the morphological gap between Coniocompsini and Aleuropterygini highlighting that the former may render the latter paraphyletic. Archiconiocompsa prisca is figured from a newly recognized specimen in Baltic amber.
