Phylogeny And Classification Of Hydropsychidae Subfamilies And Genera Of The World (Insecta: Trichoptera), Christy Geraci

All Dissertations

The family Hydropsychidae is nearly ubiquitous in streams and rivers, with over 1600 described species worldwide. Hydropsychidae is ecologically important and its larvae play key roles as indicators of water quality. Conflicting morphological characters have obscured the evolutionary history of the subfamilies, and the wide diversity of phallic morphology among Hydropsyche sensu lato species has created unstable classification systems that have been disputed among authors. My research used five nuclear ribosomal and mitochondrial COI fragments to infer a molecular phylogeny for Hydropsychidae subfamilies and genera, focusing particularly on the Hydropsychinae and the Hydropsyche sensu lato lineage. The monophyly of four …
