The South American and cis-andean lizard genus Tropidurus has a complex taxonomic history. Most species were recently described and previous revisions included few specimens from the southern part of the continent. Tropidurus torquatus has the broadest geographic distribution in the genus and several morphological and ecological differences were described within its distribution. We analyzed the geographic variation in external morphological characters of Tropidurus torquatus, including large number of samples from southern Brazil. Tropidurus catalanensis is revalidated and Tropidurus imbituba sp. nov., with a restrict distribution in the southern coast of Brazil, is described. The new species is distinguished from Tropidurus catalanensis by the number of dorsal scales. It can be distinguished from T. catalanensis and T. torquatus by a distinct orange ventral coloration in adults, which can reach the lateral portion of the body in adult males. Our analysis also suggests that at least two other undescribed species could be recognized under the name Tropidurus torquatus in southeastern and central Brazil.

Throughout life, animals must maintain homeostasis while coping with challenging events. The period after reproduction can be challenging for oviparous females to maintain homeostasis since they direct most of their energy stores to vitellogenesis, possibly increasing the vulnerability to stressors. Changes in glucocorticoids' (GC) secretion promote various behavioural and physiological adjustments daily and to restore balance after facing stressors.

Environmental conditions often affect developmental processes and consequently influence the range of phenotypic variation expressed at population level. Expansion of urban sites poses new challenges for native species, as urbanization usually affects the intensity of solar exposure and shade availability, determining the thermal regimes organisms are exposed to. In this study, we evaluate the effects of different developmental conditions in a lizard commonly found in Brazilian urban sites.

Article Synopsis
- The use of various organisms in Evo-Devo research enhances our understanding of biodiversity and evolution, with a focus on vertebrate groups like lizards and snakes.
- Standardized protocols for egg incubation and embryo manipulation are crucial for studying specific species, yet only a few squamate species have accessible lab maintenance protocols.
- This resource article provides a simple guide for incubating Tropidurus catalanensis eggs, detailing how different environmental factors like temperature and humidity affect development, hatching success, and morphotypes, thereby promoting more research in this area.

We compared microhabitat and body temperatures in the field with thermal preferences of Tropidurus catalanensis to investigate if they match or diverge as demonstration respectively of suitability or poor-quality of the thermal environment. As T. catalanensis is subjected to variable thermal conditions along its distribution and may be jeopardized by the climate change, we measured its thermal preferences after exposure to milder (17 °C-27 °C) and warmer (22 °C-32 °C) thermal conditions to evaluate acclimatory responses and tolerances and vulnerabilities to warming.

Theoretical models predict that lizards adjust their body temperature through behavioral thermoregulation as a function of food availability. However, behavioral thermoregulation is also governed by interactions among physiological and ecological factors other than food availability, such as hydration state, and sometimes it can even conflict with the locomotor activity of animals. Here, we aimed to investigate the role of food intake and hydration state on behavioral thermoregulation and voluntary locomotor activity in the lizard We hypothesized that food intake can influence behavioral thermoregulation via an interaction with hydration state.
