Gyropus emersoni Méndez, 1969

Gyropus emersoni Méndez 1969: 497, fig. 1 (male habitus, dorso-ventral view), fig. 2 (male genitalia, dorsal view), fig. 3 (female terminalia, dorso-ventral view). Type locality: Panama, Gamboa, Canal Zone. Type host: Proechimys semispinosus (Tomes) . Typology: Holotype male, ‘allotype’ female, sixteen male, twenty-five female, and four nymphal paratypes held by USNM. Of these, some paratypes were distributed: four male and four female paratypes at BMNH, and two male and two female paratypes at BPBM. Additionally, some paratypes held by SEMC, GML and KCEC (Méndez 1969: 499).

Emerson and Price 1981: 44 (host-parasite checklist). Cicchino and Castro 1990: 322 (checklist of Gyropus species on Echimyidae). Price et al. 2003: 77 (checklist).

Distribution. PANAMA (Panamá).

Hosts. Proechimys semispinosus (Echimyidae), + Zygodontomys brevicauda (Allen and Chapman) (Cricetidae) .

Remarks. Although Méndez (1969) collected a pair of lice from two different host individuals of Zygodontomys cherriei (= Z. brevicauda), we believe that these findings are the result of contamination. Without explanation, Price et al. (2003: 77) did not consider this cricetid species as a host of G. emersoni .
