          Abstract

          Objetivo. Determinar la distribución y afinidades biogeográficas de los galateoideos de aguas colombianas con base en la literatura y muestras recolectadas durante expediciones realizadas entre 1999 y 2002. Materiales y métodos. Se recolectaron ejemplares en 100 estaciones entre 20 y 550 m de profundidad en el Caribe y Pacífico colombiano. El material recolectado, junto con la información geográfica existente en literatura para las especies conocidas para Colombia se emplearon para realizar mapas de distribución, los cuales se compararon con el “Mapa de ecorregiones marinas del mundo”. Resultados. Se obtuvo la información geográfica para 3247 ejemplares recolectados de 18 especies de los géneros Agononida, Anomoeomunida, Munida, Munidoposis y Pleuroncodes, y se complementó con la obtenida a partir de la literatura para las 40 especies de la superfamilia con presencia conocida en aguas colombianas. Se generaron cinco grupos principales de distribución: especies restringidas al Caribe, al Caribe y Atlántico occidental, Anfiatlánticas, restringidas al Pacífico oriental y Anfiamericanas. Se encontró que el 53 % de las especies recolectadas en el Caribe se presentan también en la provincia Atlántico Norte Cálido-Templado, y para el Océano Pacífico la mayor afinidad se da con la provincia Pacífico Oriental Tropical. Conclusiones. Los galateoideos en aguas colombianas presentan ámbitos geográficos y batimétricos amplios, presentándose simpatría entre algunas especies. Las de aguas someras presentan mayores restricciones que aquellas de distribución en aguas profundas. Los mecanismos de distribución de las especies corresponden con el ciclo de vida de cada una y las corrientes predominantes en las provincias.

          Objective. Determine the distribution and biogeographic affinity of the galateoid species found in Colombian waters. The study is based upon bibliographic data and samples collected during expeditions between 1999 and 2002. Materials and methods. Samples of galateoids were collected from 100 locations, from depths ranging between 20 and 550 m, along the Pacific and Caribbean coasts of Colombia. The collected material and geographic information were used to create distribution maps, which were compared with the Marine Ecoregions of the World classification. Results. A total of 3247 specimens of 18 species of the genera Agononida, Anomoeomunida, Munida, Munidoposis y Pleuroncodes were collected in the Caribbean and Pacific regions, and the information was completed with bibliographic data from 40 species of the superfamily with known presence in Colombian waters. Five main distribution groups of species were established: Caribbean, Caribbean and Western Atlantic, pan-Atlantic, Eastern Pacific, and Pan-American. Comparisons with the Marine Ecoregions of The World Map showed that 53 % of the collected species in the Caribbean are also present in the temperate region of the North Atlantic and the East Tropical Pacific province. The greatest affinity among the Colombian Pacific species was found in the Eastern Tropical region of the Pacific Ocean. Conclusions. Ample geographic and bathymetric ranges of Galateoids are present in Colombian marine environments, showing a sympatric distribution among some species. Shallow water species presented more restrictions than deep water ones. The distribution mechanisms of the species correspond with their life cycle and the predominant currents of each province.

              Catalogue of squat lobsters of the world (Crustacea: Decapoda: Anomura—families Chirostylidae, Galatheidae and Kiwaidae)

              Taxonomic and ecological interest in squat lobsters has grown considerably over the last two decades. A checklist of the 870 current valid species of squat lobsters of the world (families Chirostylidae, Galatheidae and Kiwaidae) is presented. The compilation includes the complete taxonomic synonymy and geographical distribution of each species plus type information (type locality, repository and registration number). The numbers of described species in the world’s major ocean basins are summarised.
