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 .
