Abstract: 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).
Intraspecific morphological variation of P. albiventris is discussed, and
detailed figures are given. A portion of the mitochondrial cytochrome oxidase I
(COI) gene was sequenced from some species of Myrsidea and Penenirmus in order
to assess their relative genetic divergence. An updated list of all species of
lice recorded from wrens, including their geographic distribution, and a
host-louse list are also given.
