Two significant new snakeflies from Baltic amber, with discussion on autapomorphies of the order and its included taxa (Raphidioptera)

Abstract

Succinoraphidia exhibens gen.n., sp.n. (Raphidiidae: Succinoraphidiinae subfam.n.) and Succinofibla aperta gen.n., sp.n. (Inocelliidae) from Baltic Amber are described and figured. Both male holotypes are significant for giving access to their genital sclerites, allowing comparison with relevant structures of extant species. The erection of the new subfamily Succinoraphidiinae as the sister group of the Raphidiinae (comprising all other known members of the family), triggers reconsiderations concerning reliable autapomorphies of Raphidioptera, which are discussed. As a consequence, the Jurassic Hondelagia and Priscaenigma have to be dismissed from the order.
