Abstract (en):
Based on specimens housed in a scientific collection, besides literature and field observations, we present an updated list of the herpetofauna of the south-central region of Caldas, Colombia. The composition of anurans, lizards and snakes was compared with other Colombian assemblages. In addition, all species were categorized according to the extent of its distribution range. A total of 36 amphibians (35 anurans and one salamander) and 38 reptiles (15 lizards, 22 snakes and one turtle) are currently known for the south-central region of Caldas. Comparisons of the amphibians and reptiles assemblages showed low and moderate values (Coefficient of
biogeographic resemblance, range = 0,018–0,440; X̅ = 0,152), indicating that about frogs, lizards, snakes, and overall herpetofauna, the south-central region of Caldas is more akin to the Yotoco Forestal Reserve (0.326, 0.421, 0.585, 0.440, respectively). Regarding geographical distribution patterns, six species (8.1%) are endemic to the Northern region of the Cordillera Central, 40 species (54%) correspond to elements of an Andean-tropical fauna, 14 species (18.9%) are distributed from Central America to the Andes, and eight species (10.8%) have a wide distribution throughout the continent.
Abstract (es):
Se presenta un listado actualizado sobre la herpetofauna de la región comprendida entre el centro y el sur del departamento de Caldas, con base en especímenes de colección, literatura especializada y observaciones en campo. La composición de anuros, lagartos y serpientes, se analiza y compara con otras regiones de Colombia. Todas las especies registradas fueron categorizadas según el patrón de su distribución geogrí¡fica en función de su amplitud. Un total de 36 anfibios (35 anuros y una salamandra) y 38 reptiles (15 lagartos, 22 serpientes y una tortuga), son conocidos actualmente para la región centro-sur de Caldas. Las comparaciones
de los ensamblajes de anfibios y reptiles conjuntamente mostraron valores bajos y moderados (coeficiente de semejanza biogeográfica, intervalo = 0,018–0,440; X̅ = 0,152), indicando que en cuanto a anuros (0,326), lagartos (0,421), serpientes (0,585), y la herpetofauna en general (0,440), la región analizada es más afín al bosque de la Reserva Forestal Yotoco. Seis especies (8,1%) son endémicas del norte de la Cordillera Central, 40 especies (54%) corresponden a elementos propios de la fauna andina-tropical, 14 especies (18,9%) están distribuidas desde Centroamérica hasta los Andes, y ocho especies (10,8%) presentan una amplia distribución en todo el continente.
