Review of the genus <i>Hannemania</i> (Acari: Leeuwenhoekiidae) with description the two new species in amphibians from Chile.

The genus Hannemania includes 25 species of parasites of amphibians; Chile has one species: H. pattoni Sambon, 1928. This work reviews the genus Hannemania and describes two new species from Chile: Hannemania ortizi sp. nov., a parasite of Pleurodema thaul (Lesson) (Anura: Leptodactylidae) and Eupsophus contulmoensis Ortiz, Ibarra-Vidal, Formas (Anura: Alsodidae) and Hannemania gonzaleacunae sp. nov., a parasite of E. nahuelbutensis Ortiz and Ibarra-Vidal (Anura: Alsodidae). The new species differ from H. pattoni and other nearby species principally by character states of the palp and leg setae. A comparison of the diagnostic characters for all species of Hannemania is included.
