“…Eggs numerous, oval, thin-walled, in different stages of development and containing developed larvae near vulva, 101-110 (106±6.66) long by 49-66 (57±11.8) wide. In general, the specimens here described are similar in size to those described by González and Hamann (2010) parasitizing Physalaemus santafecinus from Corrientes Province, but slightly smaller than the specimens described by Gutiérrez (1945) in R. arenarum from Buenos Aires Province, those described by Baker (1980) in Rhinella achalensis from Córdoba Province and those described by González et al (2013) in R. arenarum from San Juan Province, Argentina.…”

Two species of nematodes, Rhabdias cf. elegans (Rhabdiasidae) and Aplectana hylambatis (Cosmocercidae), were recovered from the lungs and intestine of Trachycephalus typhonius (Anura: Hylidae) captured in Formosa Province, Argentina. Morphological and morphometric data of both species are provided, and previous records of Rhabdias spp. in the Neotropical region are summarized. The finding of Rhabdias cf. elegans constitutes the first record of this genus in the Formosa Province, and the finding of A. hylambatis represents the first record of this species as a parasite of hylid frogs, and the first report in Formosa Province. Trachycephalus typhonius represents a new host for both parasites.

“…In South America, there are records of acanthocephalans in Peru (Bursey et al 2001; Chero et al . 2014), Chile (Fernandez and Ibarra 1990), Argentina (Arredondo and de Pertierra 2009; Gonzalez and Hamann 2006; Hamann et al 2006), Colombia (Goldberg and Bursey 2003), Paraguay (Smales 2007a), Ecuador (Smales 2007b), and Brazil, with distributions in the Atlantic Forest (Aguiar et al 2014; Graça et al 2017; Martins-Sobrinho et al 2017; Toledo et al 2013), Cerrado (Aguiar et al 2021; Queiroz et al 2020), Caatinga (Oliveira et al 2019; Oliveira et al 2022; Silva-Neta et al 2020), and Pantanal (Campião et al 2016; Campião et al 2014b) biomes. Although Brazil’s ecosystems remain insufficiently explored, they boast the highest diversity of acanthocephalans on the continent.…”

In Brazil, acanthocephalans parasitise anurans in several biomes. In the present study, we performed an analysis of acanthocephalan infections across 175 anuran individuals from the Cerrado biome, belonging to ten species: Boana raniceps, Pithecopus hypochondrialis, Scinax fuscomarginatus, Scinax x-signatus, Leptodactylus pustulatus, Leptodactylus macrosternum, Leptodactylus vastus, Physalaemus cuvieri, Adenomera hylaedactyla, and Elachistocleis piauiensis. We also verified the specificity of the parasites using the STD* index. Additionally, we conducted a survey of acanthocephalan infection in anurans in South America. The studied assemblage in the Brazilian Cerrado presented 57 parasitised hosts of 175 specimens (overall prevalence: 32.6%). In total, 437 acanthocephalans cystacanths were recorded, among which 286 presented the same morphotype but could not be identified, 148 belonged to the genus Centrorhynchus, and three belonged to Oncicola. Unidentified acanthocephalans had a higher prevalence in L. vastus (53.85%) and the highest intensity was in L. pustulatus (17±16). The highest prevalence of Centrorhynchus sp. was in the species S. fuscomarginatus (28.57%), while the highest intensity was observed in L. vastus (111). The taxon Oncicola sp. it had a prevalence of 3.23% and an intensity of 3 only in S. x-signatus. The highest specificity was recorded for Oncicola sp. (STD*= 1), whereas the lowest was found in Centrorhynchus sp. (STD*= 2.21). Finally, according to the survey for South America, we found ten records of acanthocephalan taxa parasitizing 58 species of anurans distributed in seven countries (Brazil with the most records).

“…Los cosmocercidos, son parásitos comunes del intestino de anfibios y reptiles, presentan ciclos de vida directos (monoxeno) y las larvas infectantes ingresan al hospedador por vía oral (Aplectana) o a través de la piel (Cosmocerca) (Anderson, 2000). Previamente han sido hallados cosmocercidos de estos géneros en numerosas especies de anuros neotropicales, incluyendo varias del nordeste argentino, entre ellos Pseudopaludicola falcipes, Rhinella major, R. fernandezae, R. bergi, R. schneideri, Leptodactylus bufonius, L. chaquensis, L. latinasus, Physalaemus santafecinus, Scinax nasicus, S. acuminatus, Odontophrynus americanus, Dendropsophus nanus, D. sanborni e Hypsiboas raniceps (Mordeglia y Digiani, 1998;González y Hamann, 2004;, 2006bHamann et al, 2006aHamann et al, , 2006bGonzález y Hamann, 2007;González y Hamann, 2008;González y Hamann, 2009a, 2009bHamann et al, 2009;González y Hamann, 2010;González y Hamann, 2011).…”

Resumen. Diversos aspectos de la historia natural de especies del grupo Leptodactylus marmoratus son escasamente conocidos y la poca información existente aborda principalmente los de la biología reproductiva. El objetivo de este trabajo es aportar información acerca de la dieta y del parasitismo de poblaciones de Leptodactylus diptyx del nordeste argentino. Para el estudio trófico, se analizó el contenido estomacal e intestinal de 22 individuos adultos, mientras que para el estudio parasitario, se examinó el tubo digestivo de 40 individuos. Se registró un total de 91 presas, clasificadas en 17 categorías, entre los cuales los himenópteros formícidos fueron los más numerosos (45%) y frecuentes (55%). Otras presas importantes fueron colémbolos, coleópteros y arañas. Los valores de diversidad de presas (índice de Shannon) y amplitud del nicho (índice de Levins) fueron 2.06 y 4.29, respectivamente. El 57.5% de los individuos examinados resultó positivo al examen de endoparásitos, entre los que se incluyen nematodos y acantocefalos. Leptodactylus diptyx representa un nuevo hospedador para los nematodos Cosmocerca sp. y Aplectana sp.
