Host and record: Leptodactylus bufonius Boulenger, 1894 (Co) , Physalaemus albonotatus (Steindachner, 1864) (Co) . Site of infection: Small intestine. Material deposited: CECOAL 0 0 101005 ( L. bufonius ), CECOAL 96040901 ( P. albonotatus ). References: González & Hamann (2006a; 2012b). Life cycle: The life cycle of these nematodes is monoxenous; the infective larvae penetrate through the skin of the hosts ( Ben Slimane et al . 1996a ; Anderson 2000 ). Oswaldocruzia mazzai Travassos, 1935 Host and record: Rhinella sp. (Ju), Rhinella marina (Linnaeus, 1758) (= B. marinus ) (Ju) Site of infection: Small intestine. Material deposited: Not specified. References: Travassos (1935 ; 1937 ). Notes: Durette-Desset et al. (2006) considered O . mazzai sensu Vicente (1981) nec Travassos (1935) as species inquirenda . Oswaldocruzia proencai Ben Slimane and Durette-Desset, 1995 (= Oswaldocruzia mazzai sensu Lent et al., 1939 nec Travassos, 1935 ) Host and record: Rhinella schneideri (Werner, 1894) (Co, Sa) , Rhinella arenarum (= Ch . arenarum ) (Sa). Site of infection: Small intestine, large intestine. Material deposited: CECOAL 0 3091901 ( R. schneideri , Co ), CH-FML 0 7444 ( R. schneideri , Sa ), CH-FML 0 7448 ( R. arenarum ). References: Ramallo et al . (2007a ; 2007c ), González & Hamann (2008) . Notes: Ben Slimane and Durette-Desset (1995) established this species from Paraguayan specimens reported as O . mazzai by Lent et al. (1946) . Oswaldocruzia subauricularis (Rudolphi, 1819) Host and record: Rhinella fernandezae (Gallardo, 1957) (Co) Site of infection: Small intestine. Material deposited: CECOAL 0 8102211 References: Hamann et al. (2013). Notes: Durette-Desset et al. (2006) established that the species reported as O . subauricularis sensu Freitas, 1955 nec Rudolpphi, 1819 should be considered as a species inquirenda .
