    Abstract
    A systematic revision of the chewing louse genus Eutrichophilus Mjoberg was undertaken to delineate the species present and clarify their hosts and distributions. This genus has been particularly problematic in that, in some cases, two or three species have been described from the same host taxon. Furthermore, the critical type material is widely scattered in collections (some was even destroyed during World War II), and the host porcupines have not been revised. We now recognize 18 species of Eutrichophilus, all restricted to the mammalian family Erethizontidae, the New World porcupines. We redescribe the 1 2 previously described species that we recognize herein and describe 6 species of Eutrichophilus new to science. A key is provided for the identification of all recognized species. We found four of the older species names (E. cercolabes Mjoberg, E. minor Mjoberg, E. cordiceps Mjoberg, and E. lobatus Ewing) to represent complexes of species, thereby accounting for the six new species: ( 1 ) the cercolabes group consists of E. cercolabes, E. andersoni, n. sp., E. australis Ewing, E. duellmani, n. sp., and E. maximus Bedford; (2) the minor group consists of E. minor, E. emersoni, n. sp., and E. claytoni, n. sp.; (3) the cordiceps group consists of E. cordiceps and E. paraguayensis, n. sp.; and (4) the lobatus group consists of E. lobatus and E. hershkovitzi, n. sp. Lectotypes are designated for E. cercolabes, E. minor, and E. cordiceps. Identities for all host species are evaluated and corrected where necessary. Resumen—Se realizó la revisión sistemática de los piojos del género Eutrichophilus Mjöberg para delinear las especies incluidas en este género y clarificar sus huespedes y sus distribuciones. Este género ha sido particularmente problemático porque en ciertos casos dos o tres especies fueron descritas desde el mismo huesped. Además, el material tipo está depositado en diferentes colecciones, algunas de las cuales fueron destruidas durante la Segunda Guerra Mundial y los huespedes puercoespines no han sido revisados sistemáticamente. En el presente trabajo se reconocen 18 especies de Eutrichophilus, todas ellas restringidas a Erethizontidae, familia de mamíferos puercoespines del Nuevo Mundo. Se redescriben 12 de las especies previamente descritas, y que se reconocen como tales, y se describen seis nuevas especies de Eutrichophilus. Se presenta una clave de identificatión de todas las especies reconocidas. Los resultados muestran que cuatro de los nombres específicos antiguos (E. cercolabes Mjöberg, E. minor Mjöberg, E. cordiceps Mjöberg y E. lobatus Ewing) representan grupos de especies y por lo tanto las seis nuevas especies se incluyen en las siguientes agrupaciones taxonómicas: (1) el grupo cercolabes incluyendo E. cercolabes, E. andersoni, n. sp., E. australis Ewing, E. duellmani, n. sp., y E. maximus Bedford; (2) el grupo minor incluyendo E. minor, E. emersoni, n. sp., y E. claytoni, n. sp.; (3) el grupo cordiceps incluyendo E. cordiceps y E. paraguayensis, n. sp.; y (4) el grupo lobatus con E. lobatus y E. hershkovitzi, n. sp. Se designan lectotipos para E. cercolabes, E. minor, y E. cordiceps. Las identificaciones de todos los huespedes fueron evaluadas y corregidas cuando fue necesario.
