Type host. Troglodytes troglodytes (Linnaeus, 1758) – Eurasian wren
Material examined: 6 ♀♀ 3 33(O.Sychra CZ110–112), ex Troglodytes troglodytes troglodytes, CZECH REPUBLIC: Ćerťák (49°34'N, 17°59' E, 400 m a.s.l.); 3. and 15.v.2007, Sychra and Literák leg. (MMBC); 10 ♀♀, 10 33, (O.Sychra PE06–15), ex Troglodytes aedon audax, PERU: Pantanos de Villa, Lima (12°13’ S, 76°59’ W; at sea level), 20–22.vii.2011, Literák leg. (MMBC).
Variability. WATERSTON (1915) provided a very detailed description of this species under the name Docophorus troglodytis from Troglodytes troglodytes borealis Fischer, 1861 from the Faroe Islands, including four figures. Subsequently, CLAY & HOPKINS (1951) briefly reviewed the main characters of the species described as Pediculus albiventris by SCOPOLI (1763), added three more figures, including male genitalia, and designated a neotype. Recently, CICCHINO (1980) reported this species on one T. aedon bonariae Hellmayr, 1919 in Argentina. He wrote that his material was similar to the description by CLAY & HOPKINS (1951) and presented only a figure of male genitalia.
We contribute detailed figures of this species (Figs 3–5). We found two minor differences between samples from different host species: (1) number of setae on the metanotum, 14 on specimens from T. troglodytes and 16–17 on specimens from T. aedon; (2) number of posterocentral setae on the female tergite VIII, 4 on specimens from T. troglodytes but only 2 on specimens from T. aedon. Also, our specimens differ slightly from the description and redescription of P. albiventris presented by WATERSTON (1915) and CLAY & HOPKINS (1951) respectively, thus increasing knowledge of the intraspecific morphological variability of this species from different geographic areas. Our setal counts and dimensions are as follows [setal counts and dimensions mentioned by WATERSTON (1915) and CLAY & HOPKINS (1951) are given in parentheses and separated by a semicolon, respectively. The nomenclature of head setae follows that proposed by CLAY (1951)]:
Czech Republic. Male (n = 3). As in Figs 3A and 4A. Head with postantennal suture, with one post-nodal and three post-temporal setae on each side, all of them short and spinelike (Fig. 5A).
