Pseudoscorpions employ phoresy for dispersal, in which one animal attaches to another for transportation. This study documents the occurrence and phoresy by Americhernes aff. incertus (Pseudoscorpiones: Chernetidae) on the fly Fannia canicularis (Diptera: Fanniidae) in a fragment of semi-deciduous seasonal Atlantic Forest, in the state of Pernambuco, northeast Brazil. The pseudoscorpions were found attached to the ventral surface of six individual flies. To our knowledge, no previous studies have shown the presence of Americhernes aff. incertus in the northeast Atlantic Forest and its use of flies as a dispersal method.
