El genero Liolaemus, es uno de los grupos naturales con mayor cantidad de especies dentro de Iguania, esta formado por dos subgeneros y varios grupos monofileticos. Uno estos grupos es el grupo monofiletico de Liolaemus anomalus , uno de los clados con mayor cantidad de arreglos taxonomicos propuestos. El grupo de Liolaemus anomalus, se distribuye desde el centro sur de Catamarca hasta el suroeste de La Pampa, Argentina, tiene un escaso numero de especies que estan asociadas a ambientes aridos y salobres, con escasa vegetacion y expuestas a elevadas temperaturas. Son lagartijas oviparas e insectivoras y sin dimorfismo sexual. El grupo de Liolaemus anomalus esta formado por especies con baja densidad poblacional. Son lagartos muy dificiles de observar y varias especies y poblaciones estan amenazadas debido a factores antropicos. En este trabajo, se realiza una revision taxonomica y un analisis filogenetico del grupo de Liolaemus anomalus. En la matriz morfologica utilizada para los a...

Lobo and Quinteros (2005) described Phymaturus spectabilis from Rio Negro Province, Argentina. The species was characterized most notably by having a brown background with a more-or-less bilaterally symmetrical pattern of bold, light tan markings, some enclosing small brown spots, on the head, limbs, body, and tail. In 2008, Scolaro et al. described P. agilis from a locality 22 km south of the type locality of P. spectabilis. It was reported to differ from P. spectabilis in its nearly uniform brown color and certain morphometric and meristic characteristics. In 2009 we collected, at the type locality of P. agilis, five adults (both sexes) with the bold pattern of P. spectabilis, and five adults (both sexes) with the uniform color of P. agilis. Subsequently, one of the females with the P. spectabilis pattern gave birth to two individuals, one of which had the pattern of P. agilis, the other with the pattern of P. spectabilis. Our analyses of specimens assignable to P. agilis and P. s...

We describe three new species of Liolaemus from Southern Argentina.These new species belong to the monophyletic Liolaemus elongatus group, included within thesubgenus Liolaemus sensu stricto. Two of the new species inhabits in southern MendozaProvince and the other one inhabits in central west Rio Negro Province. The new speciesexhibit character states that distinguish they from all other members of the L. elongatus group.Those character states include color pattern, number of scales in dorsum, shape of temporalscales, and size (among others). Although with those new species we clarify the taxonomicstatus of several populations which belongs to the L. elongatus group, many remain unknown.

The Liolaemidae family, it is formed by the genera Ctenoblepharys, Liolaemus and Phymaturus. Is the most diverse family of south Southamerica, and has experienced an impressive growth in the last 30 years. Many studies related to different disciplines within Biology have been carrying out using genera and species which are members of Liolaemidae. Nevertheless, taxonomic and phylogenetic results are the most evident. The genus Liolaemus is the most diverse of Iguania, and its number of taxa grows up considerably year after year. Phymaturus shows an intermediate diversity inside the family. However in the last decade, has tripled its species diversity. Owing to the diversity of the family, there have been proposed many taxonomic arrangement and phylogenetic proposals. Is unquestionable that the creation of the Asociacion Herpetologica Argentina in 1983, generate a fundamental advance in the study and knowledge of Herpetofauna from Argentina, and those is reflexed in the knowledge of L...

El género Liolaemus presenta una gran diversidad entre los tetrápodos actuales, al punto de corresponder al segundo género con mayor número de especies válidas descritas del infraorden Iguania. En este trabajo, se describe una nueva especie de lagartija arenícola perteneciente al subgénero Eulaemus, grupo de Liolaemus montanus, procedente de las lomas costeras de Quilca, La Chira y Ocoña, todos en la provincia de Camaná, departamento de Arequipa, Perú. Para determinar el estatus taxonómico de esta nueva especie, analizamos los caracteres morfológicos, moleculares y geográficos. Los caracteres morfológicos permitieron la caracterización y diagnóstico de la nueva especie, los moleculares fueron utilizados para realizar una inferencia bayesiana y los geográficos para determinar potenciales áreas de distribución. Este reptil se diferencia de las otras especies del grupo Liolaemus montanus en su tamaño pequeño a mediano, su conjunto de caracteres morfológicos, folidosis y patrón de color...

The genus Liolaemus is a group of lizards with more than 230 recognized species, which have been grouped in differentclades and subgroups. One of the monophyletic groups is the one of Liolaemus boulengeri or “the patch group”; this cladeitself is integrated by several monophyletic groups: the groups Liolaemus anomalus, Liolaemus wiegmanii, Liolaemusdarwinii and Liolaemus melanops. The latter group is constituted almost exclusively by Patagonian lizards, and it is ourfocal group. In the present work we describe three new species belonging to the Liolaemus melanops group. One of thenew taxon described, Liolaemus tromen sp. nov., is related to the Liolaemus fitzingerii clade, inhabits in the Center-Westof Neuquén Province, and was confused initially with Liolaemus hermannunezi, a mountain Chilean species. The secondspecies described, Liolaemus purul sp. nov., belongs to the Liolaemus telsen clade, inhabits in the center and north-westof Neuquén Province, and was confused first with Lio...

Liolaemus dorbignyi is re-described, and its type locality restricted to the Sierra de Fiambalá, Catamarca Province, Argentina. Also, Liolaemus scrocchii sp. nov., a new species of Liolaemus belonging to the L. montanus series, previously confused with L. dorbignyi , is described. This new species inhabits the phytogeographic region of Puna in Argentina at 3500 m. and is distributed in Jujuy and northwestern Salta provinces. Diagnostic characters include the color pattern, (composed of transverse paravertebral spots, that are band shaped and never reach the lateral region, and never contact the vertebral zone), and the number of scales around midbody. Several populations from different localities were considered L. dorbignyi because of their color pattern and squamation. Even though part of this confusion is clarified in this contribution, some populations still require further study.

Liolaemus is one of the most speciosus genera of lizards, having more than 200 species. It is composed of small to moderate-sized lizards that live throughout most of austral South America. Many groups whose phylogenetic relationships have been controversial compose the genus. The proposed phylogenetic relationships of these lizards have been based on data-sets from many sources. In all of the morphological data-sets, three myologycal characters have been considered particularly important:1) insertion of the m. tibialis anticus hypertrophied in association with the presence of a sharp, bladelike process of the tibia, 2) medial head of the m. flexor tibialis internus covered by a hypertrophied m. puboisquitibialis, and 3) presence of melanic pigment within the medial portion of the epimysium of the m. pterygomandibularis. Important taxonomic and anatomical questions about these characters remain: 1) Can the size of the m. puboisquiotibilis be scored with only two character states? 2)...

The genus Liolaemus is a widely distributed and very diverse natural group of lizards. The L. boulengeri group is characterized by the presence of a patch of enlarged scales on the posterior medial surface of the thigh. Liolaemus goetschi, which belongs to this group, was described by Müller and Hellmich in 1938 based on few specimens collected from Laguna Playa (Río Negro Province, Argentina). Those specimens were deposited in museums in Munich (Germany) and Breslau (Poland). The type material of L. goetschi deposited in Poland was lost and because the material in Germany is of difficult access, many populatios of other species have been confused with L. goetschi in subsequent works. In this work, L. goetschi was redescribed by using the characters currently designated for the group and the known distribution of the species was extended. The taxonomic status and phylogenetic relationships of L. goetschi within the L. boulengeri clade was also analyzed, especially with respect to L....

ABSTRACT The Liolaemus elongatus group is a group of lizards that ranges from northwestern Argentina to the southern Patagonian steppe. In this study, we describe a new species of the L. elongatus group. The new taxon is distributed in the vicinity of L. burmeisteri, L. crandalli, L. gununakuna, L. punmahuida and L. tregenzai, and posseses a combination of unique character states and morphological characters that allows its formal description as a new species. The morphological evidence provides strong support that the population under study corresponds to a new taxon. With the description of the new species, the number of members of the L. elongatus group rises to twenty-two, but many populations likely represent undescribed species.
RESUMEN Una nueva especie del grupo Liolaemus elongatus (Iguania: Liolaemidae) de la provincia de Neuquén, Argentina, con comentarios sobre su morfología genital. El grupo de Liolaemus elongatus es un grupo de lagartijas que se distribuye desde el noroeste de Argentina al sur de las estepas patagónicas. En el presente estudio, describimos una nueva especie perteneciente al grupo de L. elongatus. El nuevo taxón se distribuye en cercanías de L. burmeisteri, L. crandalli, L. gununakuna, L. punmahuida y L. tregenzai, y la combinación de caracteres morfológicos en lepidosis y morfométricos permite describirla como nueva especie. La evidencia morfológica aporta un fuerte soporte que la población estudiada corresponde a un nuevo Liolaemus. Con la descripción de este nuevo taxón el número de especies del grupo de L. elongatus asciende a veintidós, aunque hay varias poblaciones que corresponden a especies no descritas.

Se describe una nueva especie de lagartija del grupo de Liolaemus montanus, endémico de la vertiente occidental de los Andes, en la provincia de Huaytará, departamento de Huancavelica, Perú. Esta nueva especie de Liolaemus, es de tamaño medio (máximo LHC 70,1 mm), se caracteriza por presentar un patrón de coloración único en los machos, donde numerosas escamas celestes se destacan sobre el dorso del cuerpo y el vientre es de color amarillo intenso. Además tiene las escamas del dorso y lados del cuerpo subimbricadas, con quilla leve y de forma redondeada a triangular. Tanto machos como hembras tienen poros precloacales. La combinación de varios estados de caracteres morfológicos, morfométricos, de escamación, y en el patrón de coloración, diferencian claramente este nuevo taxón de las demás especies de Liolaemus, especialmente de los integrantes del grupo de L. montanus descritos para el centro y sur del Perú. Asimismo, en este trabajo, presentamos una revisión del estado taxonómico y distribución de las especies del grupo de L. montanus descritas o citadas para Perú.
