MORPHOLOGY AND CONSERVATION OF THE MESOAMERICAN SLIDER (Trachemys venusta, EMYDIDAE) FROM THE ATRATO RIVER BASIN, COLOMBIA

Abstract

RESUMEN: Las relaciones filogenéticas de la tortuga hicotea mesoamericana, Trachemys venusta, que habita la cuenca del río Atrato en Colombia ha sido controversial dado que tres subespecies diferentes han sido propuestas en los últimos 12 años: T. v. venusta, T. v. uhrigi, y T. ornate venusta. En este estudio se usó un grupo de tortugas hicoteas que fue decomisado por la autoridad ambiental para documentar su morfología y compararla con la reportada para la subespecie supuestamente distribuida en Colombia. Nosotros encontramos que la hicotea Mesoamericana colombiana es más pequeña, tiene una fórmula de las suturas de los escudos plastrales diferentes, y patrones de coloración de la cabeza, caparazón y plastrón diferentes. Adicionalmente, reportamos el pobre estado de salud de estos individuos que han soportado las condiciones de este mercado ilegal. Resaltamos la urgencia de realizar estudios de esta especie que incluyan especímenes nativos de Colombia para comprender mejor las relaciones filogenéticas de T. venusta en todo su rango de distribución, así como el realizar un control más efectivo del tráfico ilegal de tortugas en la región del Urabá colombiano.

ABSTRACT:The phylogenetic relationships of the Mesoamerican Slider, Trachemys venusta, that inhabits the Atrato River basin of Colombia have been controversial as three different names have been proposed during the last 12 years: T. v. venusta, T. v. uhrigi, and T. ornate venusta. Using a group of sliders that was confiscated by the regional authority we compared the morphology of T. venusta distributed in the Atrato River with the morphology of the subspecies putatively distributed in Colombia. We found that the Colombian Mesoamerican slider has an overall smaller size, different plastral inter-scute seam formula, and different head, carapace and plastron coloration patterns. In addition, we also report the poor health condition of these individuals that have endured this illegal trade. We underscore an urgent need for further studies of individuals indigenous to Colombia to better understand the phylogenetic relationships of T. venusta throughout its distributional range, along with a more effective control of the illegal turtle trade in the Urabá region of Colombia.
