Gyropus freitasi Werneck, 1942

Gyropus freitasi Werneck 1942: 21 , fig. 2 (famale head, dorso-ventral view), fig. 6 (detail of the endomeres and mesomeral plate), fig. 9 (female habitus, dorso-ventral view), fig. 10 (male habitus, dorso-ventral view), fig. 12 (female meso-metathorax, dorsal view), fig. 14 (female terminalia, ventral view), fig. 15 (male genitalia, dorsal view), fig. 16 (exposed male genitalia, dorsal view). 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).

Eogyropus freitasi, Eichler 1952: 76 (replacement of genus).

Distribution. BRAZIL (Ceará, Pernambuco).

Hosts. 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 .
