Liolaemus stolzmanni (Steindachner, 1891) (Squamata: Liolaemidae): Distribution update. (original) (raw)

The South American lizard genus Liolaemus has undergone a complex adaptive radiation that has resulted in the evolution of more than 200 species widely spread in an extraordinary diversity of environments, and forming a complex array of assemblages. This evolutionary complexity has puzzled systematists and taxonomists since the first species were described more than 150 years ago. Within this lineage, the Andean Liolaemus faunas have proven to be a major challenge for herpetologists. Therefore, intense research is needed in this area to clarify long-standing problems. After more than a century of taxonomic confusion, the identity of Liolaemus stolzmanni (Steindachner, 1891) is here restored as the name that must be applied to the lizards widely known as Phrynosaura (= Liolaemus) reichei Werner, 1907 from the low to midelevation deserts of Tarapacá, Chile. Since 1966, the name L. stolzmanni has been erroneously assigned to populations of Liolaemus from the high Andes of the Chile-Bolivia borderlands which, according to observations presented in this study, correspond to Liolaemus pachecoi Laurent, 1995. A lectotype and allotype for L. stolzmanni are designated and the type locality for L. stolzmanni (= L. reichei) is emended to “Deserts of Iquique, Tarapacá Region, Chile”. Furthermore, the recognition of L. pachecoi as a species distinct from L. jamesi is supported by mtDNA sequence divergence data despite the inconclusive meristic and morphometric data. In summary, I conclude that (i) the Chilean L. reichei is a synonym of L. stolzmanni, and hence, that L. stolzmanni is a species endemic to Chile, not an element of the fauna of present-day Peru and that (ii) the Chilean Altiplano populations currently recognized as L. stolzmanni are L. pachecoi, a species hitherto known only from Bolivia. Also, I report the first confirmed specimens of L. poconchilensis from Peru, a species previously known only from Chile and confused with L. reichei.

Liolaemus riodamas is a recently described lizard, only known from a very restricted river canyon in the Andes of the O’Higgins Region in Chile. The species is particular for being one of the few Liolaemus lacking the pheromone secreting glands known as precloacal pores. Here we document a second locality for this species located 30 km southwest of the type locality. This is also 500 m higher than the type locality, therefore a considerable altitudinal extension. This is a very positive discovery since the type locality of L. riodamas is intervened by a hydroelectric project, and gives hope to the conservation of this unique taxon.

Estimating the effective geographical ranges of species is central to species-oriented conservation and management. In this paper, we review the geographical distribution of Liolaemus elongatus Koslowsky, 1896 with three new records for northern Chubut and southern Río Negro provinces, Argentina. Based on detailed locality records pooled from multiple data sources, including new records obtained for this study, we revise the range of L. elongatus sensu stricto and provide geographical distribution maps comparing the previously recognized range to that proposed herein. Our results show that L. elongatus possesses a much more limited geographic distribution than previously thought, being restricted to areas south of 38°S latitude; the newly proposed range is merely half the species formerly recognized geographical distribution.

We describe a new slender species of Liolaemus of the L. alticolor-bibronii group of the subgenus Liolaemus. The new species is phenetically and biogeographically close to L. alticolor, L. paulinae, and L. puna but presents a combination of character states that differentiates it from all other species of Liolaemus. The new taxon is the first species of subgenus Liolaemus sensu stricto recorded as having supernumerary pores. The new species inhabits places where Parastrephia lucida is the predominant flora and is distributed in areas close to Putre, in the Arica y Parinacota region, northern Chile. Data on its biology, complete distribution, and conservation status are lacking.
