New Nearctic Rhyacophilidae and Philopotamidae (Trichoptera)

Abstract

Examination of additional collections of Trichoptera from various parts of North America has brought to light several new species, seven of which are described in this paper. To ascertain the placement of the new genus in Philopotamidae, it has been necessary to attempt a tabulation of related world genera, and while the resulting key is preliminary and undoubtedly imperfect, it is presented in the hope that it will be a useful step in an analysis of the family.
