New pored Leposternon (Squamata, Amphisbaenia) from Brazilian Cerrado

A new species of Leposternon is described from the Brazilian Cerrado, southwestern Goias state. The new species is diagnosed mainly by the following characters: two–four precloacal pores, 299–341 dorsal postpectoral half-annuli, 302– 349 ventral postpectoral half-annuli, 13–15 tail annuli, 118–121 precloacal vertebrae, two supralabials, two infralabials, five series of large plates in dorsal head shields, diamond-shaped pectoral scales, head length 2.6–3.2% snout-vent length, rostronasal length 20.4–23.1% head length, azygous width 30.8–41.9% head width, azygous length 40.1–51.4% head length, frontal length 23.7–38.2% head length, and prefrontal length 37.2–44.4% head length. The new species here described is the only known Leposternon restricted to the Cerrado region. Additionally, we present an updated check list of non-fossil amphisbaenians according to ecoregions in the Brazilian territory.
