Abstract
Limnephilidae is a large family within Trichoptera, consisting of 4 subfamilies (Dicosmoecinae, Ecclisomyiinae, Limnephilinae, and Philocascinae), 98 genera, and 1178 species. It is among the most diverse families within Trichoptera. It is also ecologically diverse, occupying more habitats than any other family in the order. There are currently no published generic phylogenies of Limnephilidae based on molecular data. Here we used anchored hybrid enrichment to capture and sequence 922 loci for 57 species taken from what have been considered the full range of genera in the family. We expanded the taxon sampling by adding supplementary species with DNA barcodes, 28S sequences, or containing both from other sources. We present a favored tree from the collected data. We examine the evolutionary patterns associated with larval habitat transitions and highlight instances where our preferred evolutionary tree is incongruent with current limnephilid classification.
