A western small-footed myotis (Myotis ciliolabrum) from South Dakota harbored 2 plagorchiid trematodes in its small intestine. Both trematodes were identified as Plagiorchis micracanthos Macy, 1931. This is the first report of P. micracanthos from M. ciliolabrum, and the first time this parasite has been reported in a bat from South Dakota. At least 10 other parasites are known to infect and/or infest M. ciliolabrum in North America.
