|Diagnosis||Amphisbaena talisiae can be distinguished from its congeners by a series of morphological characters, including a round head, three supralabial and three infralabial scales, postmalar row absent, four precloacal pores without a median hiatus, 205–234 body annuli, 17–29 caudal annuli, 10–14 dorsal and 14–18 ventral segments in a midbody annulus (Costa et al. 2019).|
Amphisbaena talisiae, sp. n., from Serra da Pitomba (15° 49'S, 52° 10'W), a small, slender species, is characterized by having four preanal pores, 218 body annuli, caudal autotomy on the seventh annulus (tail broken and healed), 10/14 segments to a body annulus.
Description: “Small (body length 105 mm), slender (head width 2.5 mm).
Median sutures on the dorsal aspect of the head in the following order of increasing length: (nasals, frontals), parietals, prefrontals. Frontals together oval; parietals pentagonal, moderately elongate; occipitals little differentiated from the segments on their annulus. Nasal large, nostril below and before the center on the scale. Four upper labials, second and third large, the ocular fitting into their upper angle. Fourth upper labial small, squarish. On top of it a large polygonal scale and, on top of this, another large similar scale, in contact with the ocular, the frontal, the parietal, and, behind, with an annulus of scales anchored on the parietals. Symphysial medium-sized, with divergent sides but not quite anvil-shaped. Post-symphysial almost as broad as long, seven-sided. Three lower labials, the second by far the largest, the third small, rectangular. Anterior genials moderate, in ample contact with each other, embracing in front the posterior angle of the post-symphysial. Lateral genials large, in full contact with the third labials. Posterior genials six, the outermost largest.
Body with well marked lateral sulci; no other sulci. Dorsal segments a little longer than broad, broadest ventral ones not quite 1.5 times as broad as long. Preanal pores four, hardly distinguishable. Preanal fold almost semicircular, with six scales.
Color: Dorsally burnt medium brown, darkest on the top of the head, with lighter segment sutures; ventrally uniformly light waxy yellow, the transition gradual on the flanks.” (Vanzolini 1995)
