In this paper, information is added and comments are made about two recently described Peruvian species of Liolaemus from the montanus group: L. balagueri and L. qalaywa. When L. balagueri was described, differences from L. nazca was based on a phylogenetic analysis of a single mitochondrial locus, but without including phenotypic diagnostic traits that might differentiated them. On the other hand, L. qalaywa description was based upon specimens from Apurirnac department and intraspecific variation in meristic traits were missing. In this study, we added a molecular and morphological analyses between L. balagueri and L. nazca, supporting more rigorously the separation between these two taxa. In addition, the geographic range of L. qalaywa is extended to Cusco department (southwestern Peru), intraspecific variation of morphological characteristics and geographic information up to 79 specimens are included, and the conservation issues of this species is commented.

The conservation of the biodiversity of the Patagonian steppe and monte has received scarce attention in comparison with other biomes. In order to advance specific conservation actions, it is important to provide a severe basis for the biodiversity of the area For this, it is essential to solve multiple taxonomic challenges, including the description of new species. This taxonomic resolution is crucial for categorizing the conservation status of the taxa studied. In this study, a new Patagonian species of the genus Liolaemus is formally described and categorized. The species was found in arid, hostile areas in the phytogeographic region of the Monte, in Río Negro province, Argentina. Characters of external morphology, morphometry, color pattern and folidosis were employed to describe the new species. In addition, a phylogenetic hypothesis based on morphological characters is presented, recovering a dade formed by the new Liolaemus species, L. donosobarrosi and L. tirantii as a monophyletic group, maintaining the same relationships in most of the analysis performed. The conservation category assigned to the new species was based on the modified SUMIN index, used by Asociación Herpetológica Argentina, resulting in the vulnerable species category. The population of this new species is very scarce and despite having conducted a thorough search for years, the number of registered specimens is extremely low. [ABSTRACT FROM AUTHOR]

The genus Liolaemus presents great diversity among the current tetrapods. It is the second genus with the highest number of valid species described of the Iguana infraorder. In this study, we described a new species of sand lizard from the coastal lomas of Quilca, La Chira and Ocoña that belongs to the subgenus Eulaemus and group of Liolaemus montanus, all in the province of Camaná, department of Arequipa, Peru. To determine the taxonomic status of this new organism, we analyzed morphological, molecular and geographical characters. The morphological characters allowed the characterization and diagnosis of the new species, the molecular data was used to make a Bayesian inference, and the geographic data served to determine potential distribution areas. This lizard diverges from the other species of the Liolaemus montanus group for its small to medium size, several sets of morphological characters, folidosis and color pattern. It is also the only species of the genus where the males have a pattern of lateral spots of rounded shape with dark border and green interior, from the armpits to the middle of the body. Additionally, the molecular phylogenetic results made with the Cyt-b gene indicate that it has no direct relationship with the phenetically similar species described for the group; nevertheless, there is a relationship with geographically close populations, which has not been properly described. Finally, it was determined that this lizard has a very marked endemism and its populations are not abundant. [ABSTRACT FROM AUTHOR]

Liolaemus belongs to the Eulaemus subgenus, that is included in the Liolaemus montanus group or section, and is distributed in Argentina, Bolivia, Chile and Peru. The species members of this clade inhabit arid and high altitude environments, usually above 2 800m, and have a strong tendency to herbivory and a viviparous reproductive type. In a herpetological expedition to the Salta Province highlands, Argentina, in April 2012, we collected individuals of this new species for their description. The specimens were collected with loop, slaughtered by anesthesia and deposited in the herpetological collection of Fundación Miguel Lillo in Tucumán (FML). To characterize this new taxon, we analyzed 144 external morphological characters, referring primarily to lepidosis, color pattern, and body proportions, comparing with data from 66 constituent species of the L. montanus group (45 taxa from collection specimens and 21 from literature). Description of the colors in life was made in the field and based on photographs taken during the capture. The species described in this work inhabits a very narrow mountain range area in Salta Province (Argentina), and the Atacama Region (Chile), always above the 3 600m. This new taxon shows characteristics of lepidosis and color patterns clearly different from the other species members of the L. montanus group: the maximum snout-vent length is 72.9mm; shows 74-96 scales around midbody, 89-104 dorsal scales between the occiput and hind limbs, 92-109 ventrals, precloacal pores are evident in both, males and females, and supernumerary pores in males. Also, the presence of postcloacal pores stands out as unique among all Liolaemus. This is a new character, not only for the genus, but also to all Reptilia, becoming a morphological discovery of great importance, since in reptiles only precloacal and femoral pores are known. Based on our field observations, this new Liolaemus is related to rocky environments, which are used as refuge by this omnivorous species, and when handled, very aggressive males.

We evaluated the antitumoral and antiviral activity of extracts at 10% (w/v) of leaves and bark of Calophyllum brasiliense Cambess of Satipo and Pucallpa. METHODS: CYTED, Skehan and Simmons techniques were used. RESULTS: In Anemia salina the LC50 was at 70, 5 ppm, with 95% superior and inferior limits of 136.50ppm and 36.4ppm with Probits. An inhibition on tumoral cell lines: U251(CNS Cancer), PC-3(Prostate Cancer), HCT15 (Colon cancer), MCF7(Breast cancer) and K562 (Lymphoid tissue cancer) of 109,42%, 95,67%, 96,16%, 102,68% and 95,69% respectively, with p< 0,01 was observed. In the antimitotic evaluation using Allium cepa, after 6 hours the MI of meristematic cells decreased from 13 to 1,0 at a concentration of 0,5% at 25°C. The antiviral activity on Reverse Transcriptase (RT) of the HIV-1, performed with the Lenti RT Kit, presented a LC50 of 70,2905 ug/mI (limit of 95%: 138.89ug/ml-35.5707ug/ml). We detected: alkaloids, coumarins, lactones, pentacyclic compounds, triterpens, and three compounds were isolated CBHS5, CbHS16, CbHS525354. Structural elucidation of the major components were characterized by RMNH1, RMNC13 and Mass Spectrometry and were Betulin, that has an antiinflammatory effect and betulinic acid, that has antitumoral and anti-HIV effects. DISCUSSION: Betulin and betulinic acid could be implied in the pharmacologic action of the leaves extracts of Satipo, that presented a good antitumoral and antiviral activity of 7 2,05% on RT, as opposed to Nevirapine used in the therapy of patients with AIDS, that presented 71.59%activity.
