Sibynomorphus mikanii (Schlegel, 1837)

Natural history notes.

Species of small size (n = 1), nocturnal and terrestrial ( Marques et al. 2001). A recently road-killed individual was found in an open area during the day. No diet or reproduction data was recovered for the examined specimen. Available information indicates this species is a specialist in mollusks ( Marques et al. 2001). Fecundity varies from three to 10 eggs, which may be laid in communal spawning ( Albuquerque and Ferrarezzi 2004, Pizzatto et al. 2008 a). No defensive behavior was observed for this species.

Altitudinal variation.

This species was found at a minimum of 110 m a.s.l., in Puerto Bemberg, Iguazú, Argentina and maximum of 1350 m a.s.l. in the Serra do Ouro Branco, Ouro Branco, MG ( Bérnils 2009). The maximum altitude for the species is expanded in this work, where a record occurred at 1630 m a.s.l., in the Baependi, MG. Total altitudinal range is broad with 12.3% of toponyms found below 400 m a.s.l., 30.5% above 801 m a.s.l., and 57.2% in the range between 401 and 800 m a.s.l. ( Bérnils 2009).

Distribution and habitat.

Northeast, central-west, southeast and southern Brazil (Bahia, Goiás, Maranhão, Mato Grosso do Sul, Minas Gerais, Pará, Paraná, Norte and São Paulo), Argentina and Paraguay ( Bérnils 2009, Wallach et al. 2014). The species is common in forested formations from the Amazon Forest to the Atlantic Forest, in semidecidual and riverine forests and savannah formations of cerrado ( Bérnils 2009, Freitas et al. 2014).
