Beautiful Species Of Tree Iguana Redescribed 179 Years After It Was Discovered
Tree iguanas (Liolaemus) are one of the most diverse genus of lizards in the world with 230 described species. Within these, Liolaemus nigromaculatus - the second described species of the genus Liolaemus - is usually mentioned in field guides, project baselines, scientific articles, reviews and even is the nominal species of the lizard group nigromaculatus... but always the same question is repeated: Which is this species and which is its type locality?
"For first time, we have been able to identify the area in which Meyen collected L. nigromaculatus. We have established through Meyen's own writings and the study of the species of Liolaemus that inhabit in the localities that he visited that the tree iguana L. nigromaculatus was collected in the transect or surroundings between Puerto Viejo and CopiapÃ³, in Atacama (Chile)", explains Jaime Troncoso-Palacios.
For the characterization of the holotype of L. nigromaculatus, the authors used high resolution digital photographs provided by Mr. Frank Tillack (Museum fÃ¼r Naturkunde). Use of digital pictures of type specimens has proved to be a powerful and useful tool for clarifying confusing taxonomic issues. The study was published in the open access journal ZooKeys.
