Bothrops lutzi (Miranda-Ribeiro, 1915) “ Jararaca ”

(Figs. 10.3 and 22.3)

It was recorded in the western portions of the Caatinga; close to its contact with the Cerrado in the states of Piauí, Ceará, Pernambuco, and Bahia. It occurs in altitudes of 308 to 847 m elevation in areas close to the Cerrado- Caatinga contact, being found only in highlands inside the semi-arid Caatinga. It is recognized as a Cerrado endemic (Nogueira et al. 2010, 2011). Inside the Caatinga, Loebmann and Haddad (2010) mentioned this species in high altitude areas of the Ibiapaba-Araripe Plateau, but apparently this species inhabits mainly relictual savanna vegetation in high altitudes, as it is typical and relatively common in plateau areas covered by cerrado savannas (Recoder & Nogueira 2007; Nogueira et al. 2011; Recoder et al. 2011). It has terrestrial habits, is nocturnal, and feeds montly on mammals (Martins et al. 2002; Silva & Rodrigues 2008).
