Resumo

Here, we report new occurrences of Mirinaba unidentata (G.B. Sowerby II, 1825) and review of the occurrence records M. unidentata and M. planidens (Michelin, 1831). A single shell of M. unidentata was collected in the Parque Estadual Caverna do Diabo, southern Sao Paulo state, Brazil. Moreover, material of both species deposited at the Museum of Zoology of University of Sao Paulo were observed. These two seem to have allopatric distributions, and not overlapping. Mirinaba planidens occurs in the mountain ranges shared by Sao Paulo, Rio de Janeiro, and Minas Gerais in southeastern Brazil, whereas M. unidentata occurs in the chain of mountains in southern Sao Paulo and southern Brazil. The regions where these species occur are approximately 500 km distant from each other. Due to the similarity of the shells and their distributions, it is tempting to think about these species as examples of divergence by allopatric speciation. (AU)
