Some species of pseudoscorpions perform a mechanism known as phoresy, attach themselves to other organisms for transportation. In this work, Americhernes oblongus (Pseudoscorpiones: Chernetidae) is reported as a phoront on a species of fly belonging to the genus Scipopus (Diptera: Micropezidae). A. oblongus is a new record for Panama and was collected in the town of Pirre, Province of Darien. The pseudoscorpion was found attached to the coxa of the right hind leg of the fly. To our knowledge, there are no previous reports of phoresy between A. oblongus and Scipopus sp. as a dispersal method.
