“…Finally, the differences in the evolution of genital and non‐genital traits in each group might translate into the diversity of the group per se . The least diverse group, L. lineomaculatus (~22 spp; Breitman et al ., 2013), exhibited lower evolutionary rate in genital and non‐genital morphology than the L. elongatus group, which has more species (~31 spp Ruiz et al ., 2019; Table 4). Our results show that in general, genital characters evolve at a faster rate than non‐genital characters.…”

Different studies suggest that reproductive characters evolve faster than non‐reproductive characters. Males in the order Squamata have paired copulatory organs called hemipenes, with high morphological diversity, including differences in size, shape, and ornamentation. Some studies in the species‐rich lizard genus, Anolis suggest that genital traits evolve faster than the rest of the body. However, these studies were made considering only a few traits, across a wide phylogeny, without considering species relatedness, which may inflate differences in evolutionary rates. Here, we study two phylogenetic distantly related lizard groups, which differ in the number of species, but have similar divergence times. We evaluate as follows: (1) evolutionary rate, models of evolution and phylogenetic signal among the different genital and non‐genital traits; (2) which kind of traits (genital and non‐genital) are divergent across sister species and (3) whether the species‐rich group shows a faster rate of trait change. We studied 24 Liolaemus lizard species, belonging to two monophyletic groups that differ in species number: L. elongatus' clade, which has more species than L. lineomaculatus' clade. We studied 20 different traits (9 genital and 11 non‐genital) and calculated their phylogenetic signal, evolutionary rate of change and models that best explain the evolutionary change. Our results show that: (1) in general, genital traits evolve faster than non‐genital ones in both groups, and both phylogenetic signal and best evolutionary model vary depending on the trait. (2) Genital traits diverged more among sister species within the L. lineomaculatus group, but within the L. elongatus group, both sets of traits show similar degrees of divergence. Finally, (3) the species‐rich group (L. elongatus), has the highest genital evolutionary rate but also the highest non‐genital evolutionary rate.

“…1). In contrast, the L. elongatus group ( Liolaemus sensu stricto) is more diverse (~31 spp, Ruiz et al ., 2019) and has a more extended distribution (from northern Argentina 26°40'29.48"S; 65°48'20.06"W. to Patagonia, Argentina 45°27'0.06"S; 69°42'0.74"W.), following the Andes mountain range, and the central region of Chile (Fig. 1).…”

“…Abdala et al [22] noted that from 1998 to 2007 an average of five new species of Liolaemus were described annually, but from 2008 to date, 66 new species have been described for an average of 6.5 new Liolaemus per year. The principal evidence used in support of these taxa has been morphological [1, 6, 15, 16, 90, 91, 92, 93, 94], molecular [14, 66, 95, 96, 97, 98, 99], morphological and molecular [5, 19, 100, 101, 102], morphological, molecular, and cytogenetic [18], and phylogenetic [2, 103]. This taxonomic research demonstrates that Liolaemus have morphological characters that are informative for the delimitation of species and that many of these characters are likely to be adaptive, allowing these lizards to exploit a wide range of habitats and macroenvironments, as expressed by the high species richness of the genus [104].…”

Description and phylogeny of a new species of Liolaemus (Iguania: Liolaemidae) endemic to the south of the Plurinational State of Bolivia

The Liolaemus montanus group is a diverse group of lizards that ranges from central Peru to southwestern Mendoza, Argentina, including much of the Plurinational State of Bolivia (“Bolivia”) and Chile. The species of this group mainly inhabit high elevation areas with cold temperatures. In the last years, several species of this group have been described, mostly in Argentina and Chile. In Bolivia, there are at least thirteen valid species belonging to the L. montanus group. In this study, we describe a new species of the L. montanus group with a marked endemism in the Cordillera de Sama of the Tarija Department, Bolivia, and a combination of unique character states that allows its formal description as a new species. The phylogenetic relationships based on analysis of 159 morphological characters suggest that it belongs to the L. montanus group, and that it is closest to Liolaemus pulcherrimus, which is found allopatrically in a small area of the Jujuy Province, Argentina. The multivariate analyses of 66 morphological characters support the phylogenetic relationships. Statistical analyses of inter-species comparisons of morphological characters are not considered the only methods due to the non-independence of some characters states among species; thus, a phylogenetic analysis is recommended. The detailed revision of specimens of the L. montanus group held in the collections of Bolivia is filling major geographic gaps and improving our understanding of the phylogenetic and biogeographic relationships of this widely distributed group of South American lizards.

“…The genus reached 257 described species in the last review (Abdala & Quinteros, 2014). However, since several species are described each year, the diversity of the genus is estimated to be approximately 265 species at current (Ruiz et al, 2019a) and according to Núñez et al (2018), 98 species of Liolaemus occurs in Chile. Liolaemus has been split into two subgenera, Liolaemus (sensu stricto) and Eulaemus, supported by both morphology (Etheridge, 1995;Laurent, 1985) and molecular evidence (Espinoza et al, 2004;Schulte et al, 2000), with each subgenus split into several groups (e.g.…”

Resumen.- Los lagartos Liolaemus habitan en el sur de Sudamérica, siendo uno de los géneros de vertebrados terrestres más diversos del mundo. Dentro de este género, las especies del grupo de L. elongatus habitan en la cordillera andina de Chile y de Argentina, y en los afloramientos rocosos de la Patagonia Argentina. Aquí, nosotros revisamos la identidad taxonómica de una población de los Andes de la Región de O`Higgins, Chile, previamente confundida con L. cristiani. Nosotros encontramos que este taxón no es asignable a ninguno de los Liolaemus actualmente descrito y proveemos una descripción para este. Preliminarmente nosotros incluimos a esta nueva especie en el grupo de L. elongatus, siendo una de las especies del grupo distribuidas más al norte.
