Abstract

We describe two new extinct caddisflies, Electroadicella kuenowi sp. nov. and Triaenodes simoni sp. nov., embedded in Baltic amber. Both species belong to the tribe Triaenodini and enlarge the family Leptoceridae to a remarkable number of 18 extinct Eocene species from Baltic amber. The extinct Electroadicella and the extant Triaenodes are possibly closely related, by a distinct synapomorphy, a recurved process from the basal plate of the inferior appendages of the ninth abdominal segment in the male genitalia.
