Comunicacion Cuadernos de Herpetología; vol. 39, no. 2 Serra do Ramalho karst area is part of the Bambuí group, the largest geomorphological unit of Brazil. It is in southwestern state of Bahia, and extends over the municipalities of Carinhanha, Feira da Mata, Coribe, and Serra do Ramalho. We inspected 34 caves of Serra do Ramalho karst area, actively looking for amphibians. We were able to find amphibians in 12 caves. We sequenced some of the specimens found for the barcode mitochondrial 16S to confirm identifications. We found 13 species of amphibians, all anurans: Rhinella granulosa, Rhinella mirandaribeiroi, Oreobates remotus, Boana crepitans, Scinax sp. 26, Scinax x-signatus, Leptodactylus macrosternum, L. troglodytes, L. vastus, Physalaemus cicada, P. cuvieri, P. albifrons, and Odontophrynus carvalhoi. As far as it is possible to say, these amphibians are using the cave to daily and seasonal retreat, where they can possibly protect themselves from the drought and heat of Caatinga during the day.

Comunicacion Cuadernos de Herpetología; vol. 39, no. 2 This study investigates the activity, habitat use, and ecological patterns of the arboreal treefrog Bokermannohyla luctuosa, based on long-term monitoring from April 2020 to August 2022 in São Francisco Xavier, São Paulo state, Brazil. Over 126 field trips, we recorded this frog 203 times across 17 sites, with significant seasonal variation in activity and habitat use. During the dry season (April to September), the animals frequently occupied waterfall spray zones, while wetter months saw decreased reliance on these habitats. Reproductive activity, including vocalizing males, gravid females, and tadpoles, was observed across multiple months, which indicates an extended reproductive period. Notable trophic interactions included predation by the larger treefrog Boana faber and the consumption of a harvestman by B. luctuosa. These findings highlight the importance of long-term monitoring to address knowledge gaps, particularly as climate change threatens amphibian habitats. Understanding seasonal microhabitat preferences can guide conservation strategies and improve fieldwork outcomes.

Comunicacion Cuadernos de Herpetología; vol. 39, no. 2 Anurans are key prey for snakes, and their decline can affect snake diversity. Defensive behaviors in frogs are diverse and include secretions, distress calls, and body inflation. Frogs of the genus Trachycephalus, known as “milk frogs,” produce sticky and potentially toxic secretions. Predation events involving these frogs are rarely documented. We observed an adult parrotsnake Leptophis mystacinus preying on an adult treefrog Trachycephalus mambaiensis in a Cerrado–Caatinga transitional area in Minas Gerais, Brazil. The frog briefly escaped but was recaptured and ingested within 10 minutes. This is the first documented case of L. mystacinus preying on T. mambaiensis. Although Leptophis species are known to prey primarily on hylid frogs, little is known about the diet of L. mystacinus. This observation supports its potential specialization on nocturnal treefrogs and suggests that it may use both visual and olfactory cues to detect inactive prey during day.

Comunicacion Cuadernos de Herpetología; vol. 39, no. 2 The vine snake Chironius brazili inhabits rocky campo rupestre environments in the Espinhaço Mountain Range, Brazil. Although species of Chironius primarily feed on anurans, we report new prey records for C. brazili, including the Cycloramphidae and the first documented case of fish predation in the genus. These records expand the known diet of C. brazili and demonstrate its ability to exploit different environments while foraging.

Articulo Cuadernos de Herpetología; vol. 39, no. 2 Basic information on the natural history of species is essential for studies of evolutionary biology and ecology, in addition to being fundamental for developing conservation strategies. This study aimed to provide information on the activity and substrate use of Bothrops atrox in a floodplain forest in the western Brazilian Amazon. With a sampling effort of 816 personhours of time constrained, nocturnal visual search, 28 observations of 27 individuals were made, of which 16 were adults and 11 were juveniles. The encounter rate of B. atrox was one snake every 30 person-hours of searching, and most individuals were recorded during the rainy season. Considering the snake assemblage, Bothrops atrox represented 20.8% of the sampledsnakes, out of a total of 130 individuals of 21 species, being the second most frequent species. The ecological and morphological differences between the congeneric species B. atrox and B. bilineatus in this floodplain forest, as well as resource availability, likely influence their local abundance. These factors would also help minimize the probability of interspecific competition between these syntopic species.; Informações básicas sobre a história natural das espécies são essenciais para estudos de biologia evolutiva e ecologia, além de serem fundamentais para desenvolver estratégias de conservação.

Com um esforço amostral de 816 horas-pessoa de procura visual limitada por tempo noturna, foram realizadas 28 observações de 27 indivíduos, dos quais 16 eram adultos e 11 juvenis. A taxa de encontro de B. atrox foi de uma serpente a cada 30 horas-pessoa de procura, e a maioria dos indivíduos amostrados foi registrada durante a estação chuvosa. Bothrops atrox representou 20.8% das serpentes amostradas, de um total de 130 espécimes de 21 espécies, sendo a segunda espécie mais frequente. As diferenças ecológicas e morfológicas entre as espécies congenéricas B. atrox e B. bilineatus nesta floresta de várzea, bem como a disponibilidade de recursos, provavelmente influenciam a abundância local das espécies. Esses fatores também podem ajudar a minimizar a probabilidade de competição interespecífica entre as duas espécies.

Comunicacion Cuadernos de Herpetología; vol. 39, no. 1 El individuo fue encontrado inmovil sobre el asfalto de la Ruta 118. Se tomaron fotografías sobre la ruta, luego fue recogido y depositado en la vegetación circundante, donde fue fotografiado y posteriormente liberado. El especimen fue catalogado como adulto, comparando el largo total aproximado con estudios previos (Boulegner, 1891; Etheridge y Williams, 1991), aunque no fue posible determinar el sexo. Este nuevo registro se encuentra a 30 km (al suroeste) del punto más austral conocido para la especie en nuestro país, es la segunda observación en el Parque Nacional Iberá, 16 años posterior a la primera, y aporta una nueva observación para la provincia de Corrientes

Comunicacion Cuadernos de Herpetología; vol. 39, no. 1 This record represents a range extension for A. pallidipectoris, highlighting the importance of urban biodiversity monitoring in areas traditionally considered outside the species’ range. 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).

Comunicacion Cuadernos de Herpetología; vol. 39, no. 1 No Brasil, C. nigropunctatum tem ampla ocorrência (Guedes et al., 2023), sendo encontrada na Amazônia, Floresta Atlântica, Cerrado e na Caatinga. No nordeste brasileiro, apresenta registros nos estados do Maranhão, Piauí, Ceará, Paraíba, Pernambuco, Alagoas, Sergipe e Bahia, distribuídos em áreas de baixa a alta altitude (80-1.114 m a.s.l.), com temperatura média anual de 21 a 27°C e precipitação média anual entre 447 e 1.467 mm (Vanzolini, 1981; Ávila-Pires, 1995; Borges-Nojosa e Caramaschi, 2003; Franzini et al., 2019; Uchôa et al., 2022). No Domínio Morfoclimático da Caatinga, C. copeoglossum pode ser encontrada, de forma disjunta, em áreas de vegetação densa e arbórea, com alguns elementos arbustivos, em solo arenoso. Tem ocorrência considerável em enclaves de floresta úmida, com elementos atlânticos (planaltos conhecidos como Brejos de Altitude) e amazônicos (Duellman, 1978; Cunha et al., 1991; Nascimento et al., 1988; Silva e Leal, 2017). Sua ocorrência foi registrada em alguns Brejos de Altitude nos estados do Ceará (Borges-Nojosa e Caramaschi, 2003; Loebmann e Haddad, 2010) e de Pernambuco (Freitas et al., 2023), e em áreas florestadas dentro da Caatinga no estado do Piauí (Cavalcanti et al., 2014; Dal Vechio et al., 2016).

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.
