Abstract

The phylogeny of Rhyacophilidae was explored with 28S ribosomal RNA (rRNA) and Cytochrome Oxidase Subunit I (COI) mitochondrial DNA (mtDNA). Eighty one rhyacophilids were included in the analysis. We found that although Rhyacophilidae was recovered as monophyletic, intrafamilial relationships are not well-resolved using this dataset. Bootstrap support was poor for intrageneric relationships and additional data will be required to present a more robust hypothesis. The recovered phylogeny places Fansipangana as the sister taxon of the rest of Rhyacophilidae. We found that Himalopsyche was nested inside the genus Rhyacophila with the verrula group sister to Himalopsyche and remaining Rhyacophila. These results and possible relationships should be tested with a more extensive data set.
