Diagnosis | Diagnosis: A small to medium sized form of Amphisbaena without major fusions of head shields, though part of the naserostral suture is lost in adults; with enormous prefrontals; with extensive posterior prolongation of frontals and enlargement of the poscoculars. The laterally compressed head is markedly arched, significandy smaller in diameter than the trunk, and set off from this by faint nuchal constriction. The rostral rip projects strongly beyend the lower jaw. The form has 239 to 245 body annuli; 17 t0 19 caudal annuli; the last of which surrounds the base of the vertically keeled caudal tip; possibly an autotomy site at the sixth to eighth caudal annulus; 14 to 16 dorsal and 16 to 20 ventral segments to a midbody annulus; and 4 precloacal pores in interrupted series. Only the lateral sulci are strongly indicated. Specimens have brown dorsal pigmentation, more emphasized in the center of a segment. This drops out by segments ventrally.
