new species of lizard of the genus Liolaemus is described. It inhabits the Patagonian steppe at the eastern of Santa Cruz Province, Argentine. Characters of external morphology, morphometry, coloration pattern and pholidosis were used for its description. In addition, phylogenetic proposals based on morphological and molecular evidence that distinguishes the proposed species from other closely related species are presented. This new lizard belongs to the L. boulengeri group, L. melanops clade, L. telsen subclade. It is a small species in relation to other species of the same genus, and its coloration pattern is distinctive within the L. telsen subclade. This combination of characters supports the candidate species as a unique species within the genus. The taxon described in this study was previously classified within the range of Liolaemus boulengeri.&#13;
However, the molecular and morphological evidence presented in this study, added to those from works clearly indicates the validity as a new species of Liolaemus.; Se describe una nueva especie de lagartija del género Liolaemus. La misma habita en la estepa patagónica al este de la provincia de Santa Cruz, Argentina. La descripción está basada en caracteres morfológicos, medidas morfométricas, coloración y folidosis. Además, se presentan propuestas filogenéticas basadas en evidencia morfológica y molecular que distingue a la especie propuesta de otras estrechamente relacionadas. Esta nueva especie de lagartija pertenece al grupo de L. boulengeri, clado de L. melanops, subclado de L. telsen. Es una especie de pequeño tamaño en relación a otras especies del mismo género, y su patrón de coloración es distintivo dentro del subclado de L. telsen. Los resultados obtenidos a partir de una combinación de caracteres morfológicos y moleculares sustentan la descripción formal de esta nueva especie. El taxón que se describe en este estudio fue clasificado anteriormente dentro del rango de Liolaemus boulengeri. Sin embargo, la evidencia presentada en este estudio sumada a las pruebas de otros trabajos, indican claramente la validez como nueva especie de Liolaemus.

<description>Articulo
Cuadernos de Herpetología; vol. 38, no. 2
The Atlantic Forest is a biodiversity hotspot and one of the most threatened ecosystems in the world. Still, its reptile fauna is poorly known, especially in its southern portion. We present here for the first time a compiled list of land and freshwater reptiles of the Island of Santa Catarina, the largest continental island off the Brazilian coast. The list was based on field observation, literature, and preserved material from herpetological collections. We recorded 36 autochthonous reptile species, including one crocodylian, one turtle, two amphisbaenians, nine lizards, and 23 snakes. We also recorded introduced populations of two exotic emydid turtles. Species composition is strongly influenced by the presence of Atlantic Forest species, but there are also some non-forest species associated with the fauna of southern South America.; A Mata Atlântica é um hotspot de biodiversidade e um dos ecossistemas mais ameaçados do mundo. Ainda assim, sua fauna reptiliana é pouco conhecida, principalmente na porção sul.&#13;
Apresentamos aqui pela primeira vez uma lista compilada de répteis terrestres e de água doce da Ilha de Santa Catarina, a maior ilha continental da costa brasileira. A lista foi baseada em observação de campo, literatura e material preservado em coleções herpetológicas. Registramos 36 espécies de répteis autóctones, incluindo um crocodiliano, uma tartaruga, duas anfisbenas, nove lagartos e 23 cobras. Também registramos populações introduzidas de duas tartarugas Emidídeos exóticas. A composição de espécies é fortemente influenciada pela presença de espécies da Mata Atlântica, mas também existem algumas espécies não florestais associadas à fauna do sul da América do Sul.

Anurans are common prey for several vertebrates and also invertebrates. In response to this predatory pressure, they exhibit various defensive behaviors. In this work we report liquid cloacal discharge, body inflation, stiff-legged posture and body vibration performed by Pleurodema borellii from San Miguel de Tucumán, northwest of Argentina. These multiple defensive behaviors performed together can hinder or disrupt the predator’s action more efficiently.; Los anuros son presa común de varios vertebrados y también de invertebrados. En respuesta a esta presión depredadora, exhiben diversos comportamientos defensivos. En este trabajo reportamos descarga cloacal líquida, inflación corporal, postura de piernas rígidas y vibración corporal realizadas por Pleurodema borellii de San Miguel de Tucumán, noroeste de Argentina.&#13;
Estos múltiples comportamientos defensivos realizados juntos pueden obstaculizar o interrumpir la acción del depredador de manera más eficiente.

In this study, we described the diet composition of males of the treefrog Dendropsophus minutus from the region of the Chapada das Mesas National Park, Maranhão, Northeastern Brazil. We collected 19 males, of which 17 had stomach contents. Of that, five prey categories were registered, with spiders being the most consumed prey item. We also observed that the snout-vent length of each male had a weak influence on prey selection. Notably, D. minutus consumed a substantial quantity of spiders. Nonetheless, further studies considering temporal variation, reproductive period, and prey availability, among others, are still needed to elucidate the role of spiders on the diet of D. minutus.

<title>Explorando el reconocimiento químico recíproco madre-cría en un lagarto Liolaemus vivíparo</title>

To our knowledge, there are no studies of mother-offspring recognition in Liolaemus lizards, even though many species have a refined discrimination capacity based on chemical signals, and some of them are viviparous with a close relationship between mothers and offspring. We studied the reciprocal chemical mother-offspring recognition in the viviparous species Liolaemus zullyae, evaluating whether both mothers and offspring can discriminate between their consanguineous relative from another who is not genetically related. Six females gave birth in the laboratory. Once the offspring were born, crossover experiments were carried out. The results suggest that mothers showed no clear evidence of discrimination of their own and other´s newborns. In contrast, newborns rubbed their faces for longer when scents were from other females than from their own mothers, suggesting that newborns may recognize their mothers.&#13;
We discuss the asymmetric mother-offspring recognition detected in this study.; A la fecha, nuestros antecedentes indican que no existen estudios de reconocimiento madrecría en las lagartijas Liolaemus, aun cuando numerosas especies tiene una refinada capacidad de discriminación basada en señales químicas y algunas de ellas son vivíparas con una estrecha relación entre madres y crías. Estudiamos en la especie vivípara, Liolaemus zullyae, el reconocimiento reciproco químico madre-cría, evaluando si tanto las madres como las crías son capaces de discriminar a su consanguíneo de otro no genéticamente emparentado. Seis hembras parieron en el laboratorio y, una vez nacidas las crías, se realizaron experimentos cruzados. Los resultados sugieren que las madres no muestran una discriminación de crías propias vs. ajenas. Las crías, sin embargo, refregaron su rostro por periodos significativamente más prolongados cuando los rastros químicos eran de la madre ajena que propia, lo que sugiere que reconocerían a sus madres. Se discute la asimetría en el reconocimiento madre-cría encontrado en este estudio.

Observation of the endolymphatic sac in the lizard Homonota borelli (Squamata: Phyllodactylidae) in Argentina. Increased endolymphatic sac size in reptiles has received little attention in the literature. We present a note based on the observation of inflated endolymphatic sacs in two female specimens of Homonota borelli (Phyllodactylidae) from an urbanized site in Argentina.&#13;
The macroscopic results indicated that the samples analyzed showed a surface with a soft and whitish dermis. Microscopically, a cystic cavity lined by simple epithelium with calcium crystals was observed. We conclude that the endolymphatic sacs presented accumulation of calcium crystals which play a role during the reproductive period in reptiles. This finding represents the first record of a macro- and microscopic analysis of inflated endolymphatic sacs in the bush lizard H. borelli in Argentina.; El aumento de tamaño de los sacos endolinfáticos en reptiles ha recibido escasa atención en la literatura. Presentamos una nota basado en la observación de sacos endolinfáticos inflados en dos ejemplares hembras de Homonota borelli (Phyllodactylidae) provenientes de un sitio urbanizado de Argentina. Los resultados macroscópicos indicaron que las muestras analizadas presentaron una superficie con dermis blanda y blanquecina. Microscópicamente se observó una cavidad tapizada por epitelio simple con presencia de cristales de calcio. Concluimos que los sacos endolinfáticos presentaron acumulación de cristales de calcio el cual desempeñarían una función durante el período reproductivo en reptiles. Este hallazgo representa el primer registro de un análisis macro y microscópico de sacos endolinfáticos inflados en la lagartija de monte H. borelli en Argentina.

Skin coloration patterns in anurans could be markedly varied due to color pattern polymorphism and the occurrence of chromatic aberrancies. Knowledge about this variability allows to understand prey-predator relationships, contributes to the characterization of taxonomic groups, and may reflects genetic variability. We report herein a characterization of dorsal and ventral color pattern polymorphisms in the Neotropical frog Physalaemus fernandezae, and the finding of chromatic aberrancies in wild tadpoles. We assessed the sexual variation of four dorsal color morphs (Broadband, Reticulate, Vertebral Line, Uniform with Urostylar Line) and two ventral color morphs (Immaculate and Maculate). We found no association about the co-occurrence of different ventral and dorsal color patterns, also regardless sex, suggesting independent evolution forces influencing on them. In addition, we found geographic color pattern variation. A color aberrancy considered as leucism was observed in tadpoles, and is reported for the first time in P. fernandezae. We suggest that the patterns frequency distributions are suggestive of an apostatic selection mechanism for the color polymorphism in P. fernandezae.

En la eco-región Pampa bonaerense, H. tectifera habita diversos complejos ecosistémicos (Pampa Serrana: Sierra de La Ventana, Pampa Interserrana: sistema de Lagunas de Punta Mogotes, Pampa Deprimida y Pampa Ondulada: núcleo de su distribución bonaerense con multiplicidad de localidades conocidas; Clavijo-Baquet et al., 2010; Di Pietro et al., 2012; Sánchez et al., 2019; Alcalde et al., 2021). La localidad aquí citada expande 95 km al sur el núcleo de distribución bonaerense de la especie en los complejos Pampa deprimida y Pampa Ondulada y lo acerca a las localidades extralimitales reportadas para la Pampa Interserrana y Pampa Serrana (Di pietro et al., 2012; Sánchez et al., 2019; Alcalde et al., 2021).</dc:description>

In this note we reviewed specimens of Rhinophrynus dorsalis previously deposited in the anuran collection of the Museo de Historia Natural- Ciudad Universitaria (MHN-CU) of the Universidad Nacional Autónoma de Honduras (UNAH) to provide additional data regarding its distribution and habitat occurrence. The specimens were identified as Rhinophrynus dorsalis based on Campbell (1999), Köhler (2001, 2011), Köhler et al. (2006), and McCranie and Castañeda (2007). They exhibit the following characteristics: truncated snout in dorsal view; small and narrow head; robust body with tiny eyes; vomerine teeth absent; four toes and a pair of enlarged digging tubercles. Duméril and Bibron (1841), Campbell (1999), and McCranie and Wilson (2002) considered these latter two features to be autapomorphic characteristics of the species.
