Tribe Dipsadini Bonaparte, 1838

In the Itajaí Valley, Atractus and Dipsas are the representant genera of this tribe. Recently occurred the synonymization of Sibynomorphus with Dipsas (Arteaga et al., 2018) , however, this change can still be premature (Zaher et al., 2019). Atractus reticulatus can be distinguished by its tribe members by the dorsal rows 15-15-15, smooth scales, dorsum with reticulated pattern, and venter immaculate (Passos et al., 2010). Dipsas species can be distinguished from Atractus by the following characteristics: dorsal formula 17-15-15 or 16-15-15 for Dipsas albifrons and 15-15-15 with dorsal pattern with clearly defined blotches for Dipsas neuwiedi and D.ventrimaculata ( Peters & Orejas-Miranda, 1970) .
