Abstract
There are eight species in two families of Raphidioptera known from Canada, an increase of one species since the prior assessment in 1979. Another four species are likely to occur in Canada based on DNA evidence and distributional records. The Barcode of Life Data System currently lists ten Barcode Index Numbers for Canadian Raphidioptera.
