Description of a new species of the Liolaemus elongatus group (Squamata: Iguania) through integrative taxonomy

Liolaemus is the genus with the highest number of lizard species described in South America up to date, with approximately 290. One of the groups within the genus, the Liolaemus elongatus group, is distributed in central-south Argentina and Chile. In this work, we describe a new species belonging to...

One of the groups within the genus, the Liolaemus elongatus group, is distributed in central-south Argentina and Chile. In this work, we describe a new species belonging to the L. petrophilus clade using an integrative approach that includes the analysis of morphological (lepidosis, morphometric, coloration and hemipenis characters) and molecular evidence (genetic distances and phylogeny). We provide information about the geological formation of the study area and the clade distribution, and present an extensive description of its natural history (including diet, habitat, behaviour, phytogeography, mode of life, and sympatric species). Additionally, we present a time divergence analysis of internal branches for all representatives of the L. elongatus group. This newly described species shows character states (morphological and molecular) that allow its clear distinction from the other members of the L. elongatus group, as well as from the remaining Liolaemus species. According to our results, the L. elongatus group originated during the Miocene, whereas the new species diverged from its sister taxon during the Pleistocene. Liolaemus es el género con el mayor número de especies de lagartijas descritas en América del Sur hasta la fecha, con aproximadamente 290 especies. Uno de los grupos dentro del género, el grupo de Liolaemus elongatus, se distribuye en el centro-sur de Argentina y Chile. En este trabajo, describimos una nueva especie perteneciente al clado de L. petrophilus usando un enfoque integrador que incluye el análisis de evidencia morfológica (lepidosis, morfométrica, coloración y caracteres de hemipenes) y evidencia molecular (distancias genéticas y filogenia). Brindamos información sobre la formación geológica del área de estudio y la distribución del clado, y presentamos una descripción extensa de su historia natural (que incluye dieta, hábitat, comportamiento, fitogeografía, modo de vida y especies simpátricas). Además, presentamos un análisis de tiempos de divergencia de las ramas internas y de todos los representantes del grupo de L. elongatus. Esta especie recién descrita muestra estados de carácter (morfológicos y moleculares) que permiten su clara distinción de los otros miembros del grupo de L. elongatus, así como de las restantes especies de Liolaemus. Según nuestros resultados, el grupo de L. elongatus se originó durante el Mioceno, mientras que la nueva especie se separó de su taxón hermano durante el Pleistoceno.
