On 27 March 2011, 20 specimens of Leptodactylus macrosternum were collected in the municipality
of Aiuaba at the Ecological Station of Aiuaba, state of Ceará, Brazil. Of the 20 frogs
examined, four were infected with lung nematodes. Five specimens of Rhabdias sp. are found.
To our knowledge, L. macrosternum is a new host for Rhabdias sp.
