Gyropus lineatus Neumann, 1912 b Gyropus lineatus Neumann 1912b: 218, fig. 4 (female habitus, dorsal view), fig. 5 (sternal plates of female). Type locality: Brazil, Pará. Type host: Kerodon moco (= Kerodon rupestris). Typology: “D’après une centaine d’individues ɗ et Ψ, recueillis, en même temps que G. porcelli perfoliatus, sur le Moco (Kerodon moco Fr. Cuv.), au Para (Brésil), par Göldi (Muséum de Paris)” (see Neumann 1912b: 220), syntypes held by ENVT. Harrison 1916: 31 (checklist). Werneck 1936a: 424 (male and female redescriptions), fig. 40 (female habitus, dorso-ventral view), fig. 41 (male habitus, dorso-ventral view), fig. 42 (female head, dorso-ventral view), fig. 43 (sternal plates), fig. 44 (female terminalia, ventral view), fig. 45 (male genitalia, dorsal view).

Tetragyropus lineatus, Ewing 1924: 21 (redescription and key to species included in Tetragyropus). Werneck 1934a: 176 (synoxenism with Monothoracius penidoi). Werneck 1934b: 281 (citation). Distribution. BRAZIL (Ceará, Minas Gerais, Pernambuco). Hosts. Kerodon rupestris Wied, + Microcavia australis (Caviidae), + Proechimys mincae, + P. iheringi, + Proechimys sp. (Echimyidae). Remarks. The three species of Echimyidae cited as a host to G. lineatus are clearly either result of a misidentification of the lice (Guitton et al. 1986; Bittencourt and Rocha 2002, 2003) or contamination among museum skins (Ewing 1924). This is one of the only two species named in Gyropus found exclusively on Caviidae. The finding of an immature on a skin of Microcavia australis (Ewing 1924: 22) needs further investigation.
