Although the presence of the individual in such an atypical environment may suggest anthropogenic introduction, either accidental or intentional, it also underlines the need to investigate overlooked or novel dispersal mechanisms.

Articulo Cuadernos de Herpetología; vol. 39, no. 1 We present the first finding in Uruguay of the recently described frog Physalaemus cristinae. Adult specimens were collected in two localities of north-western Uruguay, on the east bank of the Uruguay River: near the city of Bella Unión associated to temporal ponds of an agricultural area; and in an urban area within the city of Salto. The advertisement call consisted of a single and non-pulsed note, characteristic of P. cristinae. In addition, partial sequences of the cytochrome b gene confirmed the species identity. We consider that the presence of P. cristinae in north-western Uruguay, previously unregistered in a well sampled area, is due to recent cross-river dispersal from populations in the Provinces of Entre Ríos and Corrientes, Argentina, on the west bank of the Uruguay River.

Articulo Cuadernos de Herpetología; vol. 39, no. 1 Threadsnakes are typical burrowers with specialised diet in social insects. Climbing behaviour has been observed for some of these species although there is no consensus about the nature of such behaviour for fossorial species. In this study we describe the first climbing behaviour for Trilepida salgueiroi in an occasional observation together with the description of the sequence of defensive behaviours displayed during its capture.

Comunicacion Cuadernos de Herpetología; vol. 39, no. 1 We recorded specimens of A. brunneus in at least 14 localities from four municipalities of Mato Grosso state. The genus Allobates Zimmerman and Zimmerman, 1988 (Aromobatidae) comprises 63 species (Frost, 2024) of cryptically colored leaf-litter anurans (Grant et al., 2006), commonly known as nurse-frogs. They are distributed throughout Central and South America (in the Pacific lowlands of Colombia and Ecuador; north and west in Central America to Nicaragua; Martinique, and Amazonian drainages in Brazil, Bolivia, Peru, Ecuador, Colombia, Venezuela, Guyana, Surinam, and French Guiana; Frost, 2024). Most of the 32 species already recorded in Brazil (Segalla et al., 2021) have Amazonian distributions (Grant et al., 2006), and only two species are distributed in localities along the Cerrado ecorregion: Allobates goianus (Bokermann, 1975) and A. brunneus (Cope, 1887) (Valdujo et al., 2012).

Articulo Cuadernos de Herpetología; vol. 39, no. 1 Melanophryniscus nigricans is an endangered endemic anuran species restricted to the Tandilia Mountains in Argentina. We report for the first time the interaction between this toad species and the leech Helobdella cordobensis. We observed the interaction in a temporary pond at the “Sierra del Tigre” Natural Reserve during a breeding event of M. nigricans on February 7th, 2024. A leech was found attached to the belly of a toad and removed manually with no evidence of injury in the amphibian, suggesting a case of phoresis instead of parasitism. This report is also the first documented phoretic interaction between H. cordobensis and anurans from Argentina.

Articulo Cuadernos de Herpetología; vol. 39, no. 1 Anurans have developed a variety of antipredator behaviors, including aposematism, posturing, and leg interweaving, to enhance survival against predators. Leg interweaving, observed in species like Dendropsophus branneri and D. oliverai, involves crossing limbs and may serve as a displaced behavior rather than a true defense. Unlike species with bright aposematic colors, these frogs rely primarily on camouflage for protection. The variability and limited documentation of leg interweaving highlight the need for further experimental research to clarify its function and significance, contributing to a deeper understanding of the adaptive strategies employed by anurans under predation pressure.

Articulo Cuadernos de Herpetología; vol. 39, no. 1 Many species identification issues can be minimized by providing descriptions of the advertisement calls from specimens in the type locality. In this paper, we detail the advertisement call of Dendropsophus soaresi from six localities in the State of Piauí, Northeastern Brazil, including the type locality (Picos, PI), and expand the known distribution of the species within the state. The previous mating call description attributed to D. soaresi was based on specimens from Mambaí, State of Goiás, approximately 960 km from its type locality. We present a comparative analysis of the advertisement calls of species within the Dendropsophus marmoratus Group.

Articulo Cuadernos de Herpetología; vol. 39, no. 1 El objetivo del presente estudio fue actualizar el estado del conocimiento sobre nemátodos parásitos de reptiles en Argentina, cinco años después de la última revisión. Tras la revisión publicada en 2020 sobre nemátodos parásitos en reptiles, en este trabajo proporcionamos una lista taxonómica y sistemática actualizada de los nemátodos que parasitan reptiles en Argentina. Un total de 40 taxones de nemátodos parásitos, pertenecientes a 2 ordenes, 5 subórdenes, 12 familias y 19 géneros, parasitan 54 especies de reptiles distribuidos en 11 familias con 44 especies de lagartijas, 5 tortugas y 5 serpientes. Con respecto a los parásitos, los nemátodos de la familia Pharyngodonidae y Physalopteridae presentaron el mayor número de taxones registrados (n= 13 y n= 7 respectivamente). En cuanto a los hospedadores, los reptiles de la familia Liolaemidae fueron los más examinadas (n= 28), seguido por los de la familia Teiidae (n= 4). Los resultados de esta revisión evidencian la incorporación de 16 especies de nemátodos parásitos y 14 especies de hospedadores adicionales en comparación con la revisión del 2020. Este avance representa un progreso significativo en los estudios parasitológicos en Argentina. La información actualizada será de utilidad para la elaboración de planes y proyectos relacionados con la ecología y conservación de los reptiles en el pais.; The objective of this study was to update the state of knowledge on reptile nematodes in Argentina, five years after the last review. Following the 2020 review on parasitic nematodes in reptiles, we provide an updated taxonomic and systematic list of nematodes parasitizing reptiles in Argentina. A total of 40 nematode taxa, belonging to 2 orders, 5 suborders, 12 families and 19 genera, were found to parasitize 54 reptile species across 11 families. These included 44 species of lizards, 5 turtles and 5 snakes. Among the parasites, nematodes of the families Pharyngodonidae and Physalopteridae were the most prevalent with 13 and 7 recorded taxa, respectively. Regarding hosts, the family Liolaemidae had the highest number of examined species (n= 28), followed by Teiidae (n= 4). Compared to 2020 review, this study adds 16 new species of parasitic nematodes and 14 new host species, making a significant advancement in parasitological research in Argentina. This updated information will be valuable for developing plans and projects related to the ecology and conservation of reptiles in Argentina.

2025-05-30T00:00:00Z El objetivo del presente estudio fue actualizar el estado del conocimiento sobre nemátodos parásitos de reptiles en Argentina, cinco años después de la última revisión. Tras la revisión publicada en 2020 sobre nemátodos parásitos en reptiles, en este trabajo proporcionamos una lista taxonómica y sistemática actualizada de los nemátodos que parasitan reptiles en Argentina. Un total de 40 taxones de nemátodos parásitos, pertenecientes a 2 ordenes, 5 subórdenes, 12 familias y 19 géneros, parasitan 54 especies de reptiles distribuidos en 11 familias con 44 especies de lagartijas, 5 tortugas y 5 serpientes.
