Type locality: ‘‘Vila Nova, Bahia, Brazil’’.  
TypesHolotype: MZUSP (given as DZ 1259 in Gans 2005) 
DiagnosisDiagnosis: A small to medium-sized form of Amphisbaena wirbout major fusions of head shields; rhe head with very !arge prefrontals, short frontals and !arge parierals. The vertically compressed head is of approximarely equal diameter to the trunk and the nuchal region is only faintly constricted. The rostral rip projects but slightly over the lower jaw. The form has 204 to 223 body and 14 to 16 caudal annuli; the last of which surrounds the base of the vertically kee!ed conically segmented caudal tip; there may be an autotomy site corresponding to the extremely faintly narrowed fourth or fifth caudal annulus; 12 to 16 dorsal and 14 to 16 ventral segments to a midbody annulus, and four precloacal pores in a conrinuous series. Only rhe lateral sulci are srrongly indicated. Specimens are brown dorsally, pigmented most densely on the dorsal surface of the tail; lighter ventrally, the lightening produced by depigmentation and dropping out of color by segments. (Gans 1964: 412)
