Se caracteriza la cola en dos especies simpátricas de saurios endémicos de Ecuador. Utilizamos como técnicas de muestreo trampas de goma en ocho transectos de 500 m de distancia y trampas de caída de 80x80x80 cm. Para evaluar la condición de las colas se establecieron las categorías: intacta, ausente y regenerada. Entre 2012 y 2014 capturamos 138 saurios, 125 individuos de Stenocercus guentheri y trece de Pholidobolus montium. Alrededor del 61 % de los individuos tenían la cola intacta. Reportamos por primera vez bifurcación de la cola en Stenocercus guentheri; observamos tres individuos con esta característica.
The tail is characterized by two sympatric species of endemic saurians from Ecuador. We used glue traps in eight transects of 500 m distance and fall traps of 80x80x80 cm. The condition tails intact, absent, and regenerated were studied. Between 2012 and 2014 we captured 138 individuals, 125 individuals belong to Stenocercus guentheri and thirteen to Pholidobolus montium. About 61 % of the individuals had an intact tail. For the first time, we reported tail bifurcation in Stenocercus guentheri; three cases were observed with this condition.
