This work deals with the taxonomic description of Characella capitolii sp. nov., providing the second record of the genus Characella Sollas, 1886 for the southern Brazilian coast (Rio Grande do Sul State; 170-173 m depth). The new species is characterized by two types of oxeas, one being large and abundant, the other being small and rare; by having all tetraxons transformed into three-rayed forms; spiny microxeas in two sizes; and streptasters with straight axis (plesiasters and metasters transitional to amphiasters).
