A taxonomic catalog, including host and geographic distribution, of the species of the genus Gyropus Nitzsch (Phthiraptera: Amblycera: Gyropidae) Author Valim, Michel P.

Type locality: Brazil , Ceará, Pacoti, Serra do Ouro. Type host: Cercomys cunicularius inermis (= Thrichomys inermis (Pictet)) . Typology: Holotype male, ‘allotype’ female, and three male paratypes held by FIOC. There are paratypes of both sexes in alcohol, vial 204 in support 21, at FIOC. One male and two female paratypes were donated to BMNH (former GHE Hopkins Collection). Hopkins and Clay 1952 : 161 (checklist). Emerson and Price 1981 : 44 (host-parasite checklist).

Thrichomys inermis , + T . a . laurenteus (Echimyidae) . Remarks. Despite Werneck (1942 : 21; 1948: 70) having cited Cercomys cunicularius laurentius (= Thrichomys a . laurenteus ) as a host from which G . freitasi had been collected, both Hopkins and Clay (1952: 161) and Price et al . (2003 : 77) overlooked the original data and did not consider this species as a host of G . freitasi . In Werneck’s collection there are registries for 26 samples, all hosts identified by J. Moojen, recorded from Cercomys cunicularius inermis (= Thrichomys inermis ) and only one louse sample from Cercomys laurentius (= Thrichomys a . laurenteus ), identified by R.W. Hayman, named as G . freitasi . It is important to stress that of these 27 samples, only two of them are slide-mounted. The finding of G . freitasi on T . apereoides may be a case of host misidentification. Thus, the only known host for this chewing louse is T . inermis .
