Type locality: Brazil , Espírito Santo, São Mateus, vale do Rio Itaúnas, Ribeiro do Engano. Type host: Unknown. Typology: Holotype male, ‘allotype’ female and two male paratypes held by FIOC. There are male paratypes in alcohol, vial 260 in support 26, at FIOC. Emerson and Price 1981 : 44 (host-parasite checklist).

Trinomys panema (Moojen) (see remarks below). Remarks. Based on morphological characters such as male genitalia and abdominal chaetotaxy (Werneck 1934, 1948), G . martini matthaeensis belongs to a group of species found infesting spiny-rats of the genus Trinomys . The assumption of Hopkins and Clay (1952) is valid because the species now included in Trinomys have often been considered as members of Proechimys s . l . ( Wilson and Reeder 2005 ). Moreover, from its locality of collection, the type host could not be included within the geographic range of Proechimys s . s . ( Gardner and Emmon 1984 ; Patton 1987 ; Lara and Patton 2000 ), based on such distribution the species in the genus Trinomys knows in Espírito Santo state are T . gratiosus , T . panema , T . setosus , and T . paratus (Moojen) ( Lara and Patton 2000 ; Iack-Ximenes 2005 ). Based on the results obtained herein, (1) it is assumed that two Gyropus species are not found on the same Trinomys species, (2) that T . gratiosus is probably the correct host name to G . m . iheringi (see note for this species), (3) that T . setosus is the host of G . limai , (4) T . gratiosus and T . panema are morphologically close species ( Iack-Ximenes 2005 ) (cryptic species by Iack-Ximenes, pers. comm.), which is confirmed by the close morphological similarity between G . m . iheringi and G . m . matthaeensis ( Werneck 1948 ) . It is possible that Trinomys panema should be the correct host for G . m . matthaeensis . However, further collections of lice from this host will prove or reject the present hypothesis.
