title: Parvicapsula minibicornis n. sp. (Myxozoa, Myxosporea) from the kidney of sockeye salmon (Oncorhynchus nerka) from British Columbia, Canada.
abstract: A new species of Myxosporea Parvicapsula minibicornis is described from the kidney of adult sockeye salmon (Oncorhynchus nerka) that had recently returned from the Pacific Ocean to Weaver Creek, a tributary of the Fraser River, British Columbia, Canada. Spores are ovoid, symmetrical, with 2 pyriform polar capsules at the anterior pole. The posterior pole has 2 small, pointed projections. Mean spore dimensions are length 11.0 microm, thickness (perpendicular to suture plane) 6.8 microm, and width (in sutural plane) 7.5 microm. This myxozoan is compared to other described Parvicapsula species and a Parvicapsula sp. from netpen-reared coho salmon (Oncorhynchus kisutch).
