Hosts (prevalence; range) : Dendropsophus minutus (Peters) (3/37; 1–4), Scinax cf. similis (1/2; 1), Scinax fuscomarginatus (A. Lutz) (1/1; 2), Scinax fuscovarius (A. Lutz) (3/51; 1–3), Scinax cf. nasicus (1/12; 1), Trachycephalus typhonius (Linnaeus) (1/16; 2), Elachistocleis bicolor (Valenciennes in Guérin-Menéville) (1/40; 3), Physalaemus albonotatus (Steindachner) (1/23; 4), and Physalaemus centralis Bokermann (5/35; 1–3). Site of infection : stomach wall, small intestine, and mesentery. Stage : cysthacanth. Type host and type locality : not informed. Comments : the specific identification of some acanthocephalans is hindered because typically only immature stages are found in anurans. Acanthocephalans from Centrorhynchidae are characterized by main longitudinal lacunar canals lateral, leminiscus, cement gland, trunk unarmed, proboscis receptacle double-walled, and proboscis divided by the insertion of its receptacle into two regions (see Amin 1987 ). We found the most of these characters in our specimens, except the cement gland. These acanthocephalans are common in birds and mammals, having a trophic transmission to anurans; they can use frogs and toads as paratenic or intermediate hosts ( Kennedy 2006 ). The anuran hosts above represent new records for acanthocephalans of Centrorhynchidae .
