AbstractA new raninoidian crab, Bellcarcinus aptiensis gen. nov., sp. nov., is described from the upper Aptian of Colombia. The new genus displays a combination of traits seen among some ancient species within the Necrocarcinidae and Orithopsidae, obscuring its family placement. This taxon represents the sixth known genus of pre-Albian raninoidians worldwide, and the fourth known from Colombia, in addition to Joeranina, Planocarcinus and Colombicarcinus. Bellcarcinus gen. nov., together with other Early Cretaceous finds from Colombia and Brazil, represents early stocks of stem-group frog crabs, which indicate that tropical South America might have played an important role in the early radiation of the group. Palabras clave – Aptiano, nuevo taxón, Neotrópico, origen, Raninoidia. Un nuevo cangrejo rana, Bellcarcinus aptianicus gen. et sp. nov., es descrito para el Aptiano superior de Colombia. El nuevo género exhibe una combinación de rasgos morfológicos presente en especies tempranas de Necrocarcinidae y Orithopsidae, dificultando su asignación familiar. Este taxón es el sexto género conocido de cangrejos rana a nivel mundial en rocas de edad pre–Aptiana, y el cuarto para Colombia junto con Joeranina, Planocarcinus y Colombicarcinus. Bellcarcinus gen. nov., junto con otros hallazgos del Cretácico Temprano de Colombia y Brasil, representan linajes tempranos de raninoidios, e indican que la Sur América tropical jugó un papel importante en la temprana radiación del grupo.
