New records of chewing lice (Insecta, Phthiraptera) from Brazilian birds (Aves) collected by Helmut Sick (1910–1991)

We list the genera and species of chewing lice collected from birds by Helmut Sick, mainly from central Brazil, and particularly during the Roncador-Xingu Expedition, between 1943 and 1949. From the 123 samples studied, a wide variety of chewing louse genera and species were found, including 34 species as new records for Brazil, 37 species recorded from new Brazilian localities and 23 new host records. All material is deposited in the ectoparasite collection of the Museu de Zoologia da Universidade de São Paulo. Keywords: Heptapsogasteridae, Laemobothriidae, Menoponidae, Philopteridae, Ricinida
