Four-lined Tegu

diagnosis

Diagnosis. Tupinambis quadrilineatus differs (see Table 2 for scale counts and measurements) from the other species of the genus in the presence of 11 - 18 femoral pores (15 - 18 in Tupinambis teguixin, 20 - 22 in Tupinambis longilineus, 18 - 26 in Tupinambis palustris), 94 - 118 scales around the mid-body (94 - 124 in Tupinambis teguixin, 90 - 98 in Tupinambis longilineus, 112 - 119 in Tupinambis palustris), 113 - 138 dorsal scales (102 - 126 in Tupinambis teguixin, 110 - 121 in Tupinambis longilineus, 111 - 122 in Tupinambis palustris) and the coloration. In Tupinambis quadrilineatus, the upper lateral stripe is well-defined along the flanks, whereas in other species, it is indistinct or absent (Avila-Pires 1995, Colli et al. 1998, Manzani and Abe 2002, Harvey et al. 2012).

distribution

Distribution and habitat. Tupinambis quadrilineatus is widespread in Brazilian Cerrado, and also present in open vegetation enclaves of southern Brazilian Amazonia (Fig. 7). It is known from the states of Pará (Amazonian region), Tocantins, Mato Grosso, Goiás, Maranhão, Piauí, Minas Gerais, and in the Distrito Federal (Cerrado). Tupinambis quadrilineatus is terrestrial and diurnal, inhabits both cerrado vegetation sensu stricto as gallery forests within the cerrado, where it is found on the ground and hidden inside burrows (Manzane & Abe 1997; Colli et al. 1998; Ferreira et al. 2009; Silva et al. 2009).
