The mallophagan has been one of the genus Cummingsia Ewinghistorically most and poorly known of the chewing lice parasitizing New World enigmatic we recognized In a revision of the genus (Timm and Price, mammals. six 1985), most being found on South American of Cummingsia, of the species marsupials one species was from a South American rodent of however, family Didelphidae; the family Cricetidae. These and species and their hosts are: C albujai Timm Price,1985, from Caenolestes 1971, (Tomes); C. inopinata Mendez, fuliginosus T. erro Anthony, cinereiventer and T. laniger from Thomasomys J. A. Allen, and M. 1937, from Marmosa (Thomas); C. intermedia Werneck, dry as Thomas inca (Thomas); C pe incana (Lund); C maculata Ferris, 1922, from Lestoros brevicaudata 1922, from Monodelphis ramydis Ferris, (Erxleben) and M. domes tica (Wagner); and C perezi Timmand Price, convelatus 1985, from Caenolestes new species of the genus At that time we suggested that numerous Anthony. to be discovered. Two new species of Cummingsia remained sub Cummingsia C barkleyae have been described: Price and Emerson, from 1986, sequently im sp. and C gardneri Price and Emerson, 1986, from Marmosa Thomasomys pavida We (Tschudi). from another yet another new species ofCummingsia recently obtained The purposes of this paper are to provide of South American marsupial. species a description of this new species and discuss how it can be and illustrations and Price identified using the key to species of the genus provided by Timm are in millimeters.
