Dipsas variegata (Duméril, Bibron and Duméril 1854) Dumeril, Bibron and Dumeril 1854

Dipsas variegata (Duméril, Bibron and Duméril, 1854) “Dormideira” (Fig. 27.2) Recorded only in the state of Alagoas, municipality of Quebrangulo. This is a contact area with the Atlantic Forest, 370 m elevation. It is also recorded in Atlantic and Amazonian forests (Cunha & Nascimento 1978; Zaher et al. 2011). Quebrangulo region is covered with arboreal and bushy caatinga with strong influence of Atlantic Forest. It probably inhabits forested areas, the typical habitat of its congeners (Peters 1960). It has arboreal habits, is nocturnal, and feeds on mollusks (Cunha & Nascimento 1978).
