Historical perspective and state of knowledge of the nonavian reptiles (Vertebrata: Sauropsida) of the Department of Caldas, Central Andes of Colombia

Abstract

Studying non-avian reptiles in the Colombian Andean region has encompassed various spatial scales and historical times. The knowledge of non-avian reptile diversity in the Department of Caldas (Central Andes; 7,888 sq. km. area; intricate geomorphology) has grown significantly in recent decades, especially in the areas to the east of the department within the Magdalena Valley and near Manizales, the capital city. Here, we consolidate the data from biological collections, literature, and unpublished research in a historical synopsis of the studies conducted in Caldas with an updated account of non-avian reptile species recorded in them. We found that the records of non-avian reptiles in Caldas trace back to pre-Columbian and colonial times, with specimens in biological collections dating back over a century. This non-avian reptile richness comprises 126 species grouped in 69 genera, 25 families, and three orders. Three out of the 27 municipalities in Caldas (La Merced, Marulanda, and Marquetalia) lack validated specimens or records. Furthermore, there is limited information regarding protected areas such as Los Nevados and Selva de Florencia National Natural Parks, which demands further research to unravel the diversity patterns of this biological group within this specific segment of the Andes.
