Resumen El genero Catasetum posee distribucion neotropical con centro de diversidad en la Amazonia Brasilena. Colombia es uno de los paises mas ricos en orquideoflora, sin embargo, tambien muy poco explorado. El objetivo de la presente investigacion fue conocer la diversidad, distribucion, conservacion y especies con potencial uso en cultivo comercial de Catasetum para Santander y Colombia. Se registran 14 especies y un nuevo reporte para Colombia, C. tenebrosum . Estas han experimentado un proceso de cultivo y domesticacion para la preservacion y propagacion del material con el proposito del manejo de colecciones privadas y comercializacion. La distribucion y riqueza inter especifica se encuentra principalmente en los municipios asociados al Valle interandino del Magdalena medio, al igual que la modelacion de nicho ecologico sumando la Cordillera Oriental flanco Occidental en la region del Piedemonte, entre un rango altitudinal de 50 a 1000 m.s.n.m. Se amplia la distribucion y rango altitudinal de C . lucis , especie exclusiva de Santander y en este estudio no se encontraron poblaciones nativas de C. tricorne . En conclusion, Santander posee la mayor diversidad de Catasetum para Colombia, por lo que puede ser considerado centro de conservacion in situ y ex situ de las especies del pais. Abstract Catasetum has neotropical distribution and its diversity center is in the Brazilian Amazon. Spite of, Colombia being one of the richest countries in orchid flora, also it has been one of the least explored. For this reazon, the objective of this research was to understand the diversity, distribution, conservation and species with potential use in commercial cultivation of Catasetum to Santander Department and Colombia in general. 14 species and a new report for Colombia, C. tenebrosum were recorded. These plants have undergone a  process of cultivation and domestication, for the material preservation and propagation, with the aim to manage private collections and marketing. The Catasetum distribution and inter-species wealth is mainly related with municipalities of the interandino Middle Magdalena Valley, stands like ecological niche modeling, adding the Eastern Cordillera, Occidental flank in the region of Piedmont, between an altitude ranges of 50 to 1000 m. It marks the distribution and altitudinal range C. lucis, Santander exclusive specie. In this study the C. tricorne native populations were not found. In conclusion, the Santander Department has the greatest diversity of Catasetum in Colombia, so it can be considered a species conservation center in situ and ex situ in the country.
