A new species in theRhyacophila vagritagroup (Trichoptera: Rhyacophilidae) from Olympic National Park, Washington, USA

Researchers have identified and described Rhyacophila bifurcata, a new species of caddisfly within the R. vagrita group, discovered in Olympic National Park, Washington. This discovery contributes to the understanding of biodiversity in UNESCO World Heritage Sites by distinguishing it from its closest relative, R. milnei. The study provides a detailed diagnosis and comparative analysis of morphological traits, focusing on male specimens. By examining samples collected from the park, the research highlights the importance of thorough taxonomic studies in uncovering hidden species diversity within protected natural areas.
