A total of 114 individuals of 14 wren species (Aves: Passeriformes: Troglodytidae) were examined. Nineteen birds (17 %) of six species were parasitised with 292 chewing lice (mean intensity = 15.4 lice per bird) belonging to three genera – Brueelia Kéler, 1936, Penenirmus Clay & Meinertzhagen, 1938 (Ischnocera: Philopteridae) and Myrsidea Waterston, 1915 (Amblycera: Menoponidae). Data on the occurrence of chewing lice on wrens, including geographical distributions and some parasitological parameters – such as prevalence and mean intensity – are updated and discussed. A description and illustrations are given for Myrsidea fasciata sp. nov. from Campylorhynchus fasciatus (Swainson, 1837) from Costa Rica. Penenirmus albiventris (Scopoli, 1763) is redescribed from Troglodytes troglodytes (Linnaeus, 1758) (from the Czech Republic and Slovakia) and from T. aedon Vieillot, 1809 (from Peru). Intraspeci
