Anthropogenic pressures on aquatic systems have placed a renewed focus on biodiversity of aquatic macroinvertebrates. By combining classical taxonomy and DNA barcoding we identified 39 species of caddisflies from the Crooked River, a unique and sensitive system in the southernmost arctic watershed in British Columbia. Our records include three species never before recorded in British Columbia: Lepidostoma togatum (Lepidostomatidae), Ceraclea annulicornis (Leptoceridae), and Cheumatopsyche harwoodi (Hydropsychidae). Three other specimens may represent new occurrence records and a number of other records seem to be substantial observed geographic range expansions within British Columbia.

Respective Species

The genus Olepa is distributed in Palearctic and Oriental regions with more species in India and Sri Lanka. In the recent studies, morphological variations within the group were well established, with couple of first set of mt COI DNA barcodes for at least three species. In the present account, three new species and a new subspecies are described from the northern Western Ghats region of Maharashtra based on mt COI DNA barcode studies. Due to high morphological divergence and complete genetic homogeneity on the mt COI DNA, four morphotypes under two species are reported. Morphological and genital characters of male and female are provided along with their respective species morphotypes for the first time under this genus from India. The genitalia and the habitus of male and female are illustrated. Preliminary phylogenetic tree based on the mt COI DNA sequences available in the GenBank for the genus with the sequences for the new species also provided and discussed. Key words: new taxa, morphotype, Maharashtra, DNA barcoding, mt COI gene

The Early Cambrian olenelline trilobites are a diverse clade and have been the subject of several phylogenetic analyses. Here, three new species of Bradyfallotaspis Fritz, 1972 (B. coriae, B. nicolascagei, and B. sekwiensis) and one new species of Nevadia Walcott, 1910 (N. saupeae) are described from the Sekwi Formation of the Mackenzie Mountains, Northwest Territories, Canada. In addition, new specimens potentially referable to Nevadia ovalis McMenamin, 1987 were recovered that may expand that species’ geographic range, which was thought to be restricted to Sonora, Mexico. The results of a phylogenetic analysis incorporating several olenelline taxa, including Judomia absita Fritz, 1973 from the Sekwi Formation, are also presented herein. This species has been assigned to various olenelline genera, including Judomia Lermontova, 1951 and Paranevadella Palmer & Repina, 1993. Phylogenetic analysis suggests this species is closely related to Judomia tera Lazarenko, 1960 from Siberia. This phylogenetic relationship provides further support for the hypothesis that a close biogeographic relationship existed between Laurentia and Siberia during the Cambrian.
