A new Cummingsia (Mallophaga: Trimenoponidae) from a Peruvian mouse-opossum (Marsupialia)

Abstract

A new species of chewing louse, Cummingsia izori (Mallophaga: Trimenoponidae), is described and illustrated from a Peruvian mouse-opossum, Marmosa noctivaga (Marsupialia: Didelphidae). To date C. izori is known only from two individual hosts from the type locality in Peru; however, we suspect that this species of louse will be found on M. noctivaga throughout its range in the Amazonian basin of northern Brazil, eastern Ecuador, eastern and central Peru, and northwestern Bolivia.
