Abstract

A new chigger species of the genus Hannemania Oudemans, 1911 is described, which parasitizes the Miranda’s white-lipped frog, Leptodactylus macrosternum Miranda-Ribeiro, 1926 (Anura: Leptodactylidae) in the Caatinga. The new species differs from all other Hannemania by having the odontus with more prongs (four) than the other species, except for H. argentina Lahille, 1927 that has one to five prongs. However, the new species can be separated from the latter by its fPp and the shape of bs seta. This new species is the 29th of the genus and the seventh species of Hannemania recorded in Brazil.
