description: Vanzosaura multiscutata (Amaral, 1933) comb. nov. (Figs 12, 13)
Gymnophthalmus multiscutatus: Amaral, 1933, p. 23, figs 51–55.
Vanzosaura rubricauda: Rodrigues, 1991, p. 340.
Holotype: MZUSP 40079, adult male from the municipality of Senhor do Bonfim, (10°27′S; 40°11′W), state of Bahia, Brazil (Fig. 10), collected by E. Garbe on 1908.
Diagnosis: Vanzosaura multiscutata comb. nov. is characterized by: (1) 25–47 smooth subcaudals; (2) 10–13 femoral pores in males; (3) snout round in profile; (4) forelimbs proportionally short in relation to trunk length, with FAL 54.8 ± 0.02% of TRL in females and 57.8 ± 0.02% in males; (5) colour pattern single, complex, or intermediate, when complex, dorsal stripes merge in one continuous stripe on the snout; (6) inner row of ventral scales narrower than outer; (7) prefrontal scales usually in contact (81%); (8) medium size for the genus, with largest male attaining an SVL of 37.6 mm, and largest female attaining an SVL of 38.0 mm; (9) proportionally short tails for the genus, with an average rate of complete tails (not regenerated) in relation to body size (TAL/ SVL) of 1.65 ± 0.10.
Measurements of holotype (in mm): SVL 33.4; INL 11.0; TRL 19.1; HH 3.3; HW 4.3; HL 6.4; FEM 4.4; TIB 3.5; FTL 5.5; HUM 2.7; FAL 5.2.
Variation: Vanzosaura multiscutata comb. nov. is sexually dimorphic (Vitt, 1982), with females slightly larger than males (ANOVA, F 1,336 = 8.39, P <0.05). Females have a larger TRL (ANCOVA, F 1,336 = 141.95, P <0.01), whereas males have significantly larger head dimensions (HH, HW, and HL) and longer limbs (FEM, TIB, HUM, and FAL) (ANCOVA, P <0.01). Some populations of V. multiscutata comb. nov. are highly polymorphic in colour pattern (Delfim & Freire, 2007), especially at the Cariri/Seridó region of Caatinga (the states of Rio Grande do Norte, Paraíba, and Pernambuco), and at the right bank of the São Francisco River (Xique-Xique, state of Bahia). In most localities, however, the ‘complex’ pattern is the only one present (Fig. 5).
Distribution and natural history: Vanzosaura multiscutata comb. nov. is widely distributed in the Caatinga of north-eastern Brazil, at low to moderate elevations (Fig. 10). A single population was found within the eastern Cerrado, in a dry forest habitat in the municipality of Santa Maria da Vitória, state of Bahia, representing a potential contact zone. The species is found in open habitats, and occupies a variety of microhabitats over sandy or rocky soils (Vanzolini et al., 1980; Vitt, 1995; Delfim & Freire, 2007). The species is cryptic in its activity patterns, and feeds upon a variety of small-sized arthropods such as spiders, roaches, and termites (Moraes, 1993; Vitt, 1995). Reproduction is continuous for both males and females in the two populations studied in Caatinga, with year-round oviposition, and females produce multiple clutches of two eggs (Vitt, 1982; Moraes, 1993).
