Diagnosis | DIAGNOSIS: A form of Amphisbaena without major fusions of head shields; with the nasals the largest segments of the head and divided from the frontals by a peculiar V-shaped suture; without enlarged malars; with two supralabials and one and a halfinfralabials. The form has 225 to 228 body annuli; apparently more than 15 caudal annuli (the tail is broken in both types); no caudal autotomy constriction; 12 to 13 dorsal and 16 to 17 ventral segments to a midbody annulus; and four round precloacal pores. The color of preserved specimens is a uniform dark brown dorsally, fading to a lighter ventral coloring. The tendency toward darkening of the rectangular segmental centers is only faintly apparent under the microscope (Gans 1963: 13).

Etymology | The specific name is a homage to Dr. Paulo Emílio Vanzolini (1924-2013), one of the most distinguished Brazilian zoologists. About Vanzolini see Heyer (2004), Bastos & Sa 2011, and Dirksen 2013. |
