First record of Mirinaba cadeadensis (Gastropoda: Strophocheilidae) in an anthropogenic shell mound from the Paraná coast, Southern Brazil

Mirinaba cadeadensis Lange de Morretes, 1952 is restricted to the Paraná state, and found at the municipalities of Morretes, Säo José dos Pinhais, Paranaguá, Matinhos, and Guaratuba, associated to the Serra do Mar mountains. In this paper, we report the first record of this species in an anthropogenic shell mound. Two shells of M. cadeadensis were located in the internal stratigraphic layers of the Boguagu shell mound. This is also the first shell mound record for Mirinaba.
