Sibynomorphus mikanii (Schlegel, 1837) “Dormideira”

(Figs. 18.6 and 31.2)

It was recorded in the states of Ceará, Bahia, and Minas Gerais. Except for two records in contact areas, all other records are above 560 m elevation. It is also widely distributed in the Atlantic Forest, Cerrado, and Pantanal regions ( Marques et al. 2001, 2005; Nogueira et al. 2010). Inside Caatinga, it inhabits open areas either in transitional, next to Atlantic Forest, and on highland areas. It has terrestrial habits, is nocturnal, and feeds on mollusks ( Marques et al. 2001).
