Fifteen bryozoan species in 11 families are described, comprising two cyclostomes and 13 cheilostomes. Two cheilostome genera and seven species are new: Antropora guajirensis n. sp., Calpensia caribensis n. sp., Atoichos magnus n. gen. n. sp., Gymnophorella hadra n. gen. n. sp., Cribrilaria multicostata n. sp., Cribrilaria nixor n. sp., and Figularia bragai n. sp. Eight species are identified only at genus level and remain in open nomenclature. Of the species found, 27% have erect colonies and 73% encrusting colonies. Both types contributed to the reef framework and produced sediment. The observed bryozoan diversity was higher in the barrier reefs than in the lagoonal patch reefs. ; Departamento Administrativo de Ciencia, Tecnologia e Innovacion Colciencias 728 ; Departamento Administrativo de Ciencia, Tecnologia e Innovacion Colciencias 7277 569 33195 ; Ecopetrol S.A. ; Smithsonian Institution Smithsonian Tropical Research Institute ; University of Zurich ; Universidad del Norte ; National Science Foundation (NSF) EAR 0957679 ; National Geographic Society ; Anders Foundation ; 1923 Fund ; European Research Council (ERC) 724324
