Gyropus ribeiroi Werneck, 1935 a

Gyropus ribeiroi Werneck 1935a: 598 (brief description). Type locality: Brazil, Mato Grosso, Campo Novo do Parecis (= Campos Novos da Serra do Norte). Type host: Scapteromys gnambiquarae (= Kunsia tomentosus ( Lichtenstein)) . Typology: Holotype male, ‘allotype’ female, eleven male, seven female, and twenty nymphal paratypes held by FIOC. Two paratypes were donated to BMNH.

Distribution. BRAZIL (Mato Grosso).

Host. Kunsia tomentosus (Cricetidae) .

Remarks. This is the only species of Gyropus that parasitizes a cricetid rodent (see Table 1). Its original description was based upon a set of ten pairs from two host individuals; in addition, its genitalias, head and body chaetotaxy are distinct from the other morphotypes in the genus ( Werneck 1935a:598, b:424, 1948: 62). The host associations of Zygodontomys brevicauda ( Méndez 1969: 499) and Oryzomys laticeps ( Werneck 1948: 58) were based on few specimens. Therefore, we regard these associations as the result of contamination. We stress that in both cases the morphotypes (including male and female genitalias and general cheatotaxy) in question were typically from species found on Proechimys spp.
