New systematic data for the North American caddisfly genera Lepania, Goeracea, and Goerita (Trichoptera : Limnephilidae) /

In a brief synopsis of the North American genera Lepania, Goeracea, and Goerita, larvae and pupae are described for the first time for Lepania cascada Ross, Goeracea genota (Ross), Goeracea oregona Denning, and Goerita betteni Ross.Keys to larvae, males, and females are given for the two species now known in each of the genera Goeracea and Goerita.For Lepania cascada an analysis is made of systematic characters of larvae, pupae and adults, demonstrating the probability that true affinities of the species lie with the limnephilid subfamily Goerinae rather than with the Apataniinae, to which it has been most recently assigned.A new tribe, Lepaniini, is created in the Goerinae for the genus.Based on retention of several primitive characters, Lepania is regarded as a genus of unusual phylogenetic significance, annectent between the ancestral stock of the Limnephilidae (auct., excluding Goeridae) and the Goerinae, treated in this paper as a subfamily of the Limnephilidae.
