Tribe Tachymenini Bailey, 1967

Members from this tribe usually have a small size, opisthoglyphous dentition, elliptical pupils, and a post-orbital stripe ( Bailey, 1967). In the Itajaí Valley, Gomesophis , Thamnodynastes , and Tomodon are the representant genera from this tribe (Bérnils et al., 2001). Gomesophis brasiliensis has dorsal rows in 17-17-15, smooth scales with apical pits, and a brownish-green dorsal color, with stripes (Gonzalez et al., 2014). Species from the genus Thamnodynastes show dorsal pattern checkered anteriorly and dorsal rows in 19-19-15 (Franco et al., 2017).Finally, Tomodon dorsatus has 17 scale rows at mid-body ( Harvey & Muñoz, 2004), grey dorsal background color with dark marks, and black oral and cloacal mucosae ( Quintela & Loebmann, 2009).
