On 27 occasions at least one louse (3.7%) was collected from six host species. Based on external morphological characters, at least two species of chewing lice could be preliminary identified (family: Menoponidae), including Actornithophilus umbrinus (Burmeister, 1842) and Austromenopon sp. A. umbrinus was found in the Western Sandpiper (Calidris mauri), Least Sandpiper (C. minutilla), Stilt Sandpiper (C. himantopus), Semipalmated Plover (Charadrius semipalmatus) and Wilson&#39;s phalarope (Phalaropus tricolor), while Austromenopon sp. is presumably the first record collected from the Surfbird (Aphriza virgata). These findings indicate that the distribution of these chewing lice species covers at least the regions around the equator (latitude 0&deg;) until the Arctic in the north, but probably also includes the entire winter distribution area of the host species. This is the first study of chewing lice from Ecuador&#39;s mainland coast and more research is required to understand the host-parasite ecology and ectoparasitic infection in shorebirds stopping over the region.</p>
