A pseudoscorpion was found in the underfur of a feral raccoon (Procyon lotor) captured in western Tokyo in December 2019. Based on the morphological features, we identified the specimen as Haplochernes sp. This arboreal pseudoscorpion rides other arthropods and small mammals for dispersion, but little is known that the species rides medium-sized mammals such as raccoons. To our knowledge, this is the first case report of Haplochernes sp. riding a feral raccoon. Given that raccoons are an invasive species in Japan, further records of pseudoscorpions riding feral raccoons may elucidate the relationship between feral raccoons and pseudoscorpions.
