Contributions to the systematics of the caddisfly family Limnephilidae (Trichoptera) I /

Several genera of limnephilid Trichoptera occurring in western North America are particularly significant in the phylogeny and classification of the family because of their ambiguous relationships with other taxa.This paper provides new data from larval and pupal morphology for certain of these critical genera: [mania (Scotti sp.nov.), Manophylax gen.nov.(annulatus sp.nov.) and Moselyana (comosa Denning).Adults of these species are also described, along with all stages of a species of Apatania (arizona sp.nov.).Preliminary assessment of ancestral and derived characters is made for larvae of the Limnephilidae.Using these criteria, analysis of larval characters is made for the limnephilid subfamilies and for the genera Moselyana, Imania, and Manophylax.The analysis indicates that these three genera are not congruent with any of the subfamilies as now constituted, including the Apataniinae with which the two former genera have been classified.The analysis further indicates that larvae of Imania and Moselyana have few derivative characters in common, suggesting that these two genera are not as closely related as has been interpreted from the adults.
