Five species of Laboulbenia are recorded from 15 species of Carabidae (Coleoptera) of the Galápagos Archipelago. Laboulbeniales were found on seven of the 15 larger Galápagos Islands. L. sanjoaquina sp. nov. is described from Platynus (subgenus Dyscolus) species, endemic to San Cristobal, L. galapagoensis sp. nov. from Tachys species, occurring on several Galápagos Islands and L. appendiculata sp. nov. from a Bradycellus species, occurring on Pinzon. The genera Selenophorus and Calosoma are new host records of L. flagellate, this being the first definite record of a Laboulbenia-infested Carabini under natural conditions. In general, most of the Laboulbeniales have been observed in more humid conditions, mainly from coastal littoral habitats and the fern-sedge vegetation zone at higher elevation on Galápagos islands and volcanoes. L. galapagoensis and L. appendiculata are assumed to be dioecious. Together with L. inflate, three presumably dioecious species thus occur on the Galápagos Islands. Characters, a distribution map and an identification key are given for the Laboulbenia inflate species-group.
