RESUMO: Hister cavifrons Marseul, 1854 (Coleoptera: Histeridae) is a common species in Brazilian territory mostly associated with animal carcasses that has previously been recorded in the Amazon, Atlantic Forest, and Cerrado biomes across several Brazilian states, ranging from the North to the South of the country. The highest number of records is from the state of Paraná, while Santa Catarina has only two records from inland municipalities. This note presents the first record of H. cavifrons on the coast of Santa Catarina specifically in the municipality of Florianópolis and the third for the state. The species was sampled in Biguá [Nannopterum brasilianum (Gmelin, 1789) (Suliformes: Phalacrocoracidae)] carcass, an aquatic bird commonly found along the Santa Catarina coast, marking the first record of this species associated with this animal, during the month of April (autumn season).
