    Description of a new species of Xenopholis (Serpentes: Colubridae) from the Cerrado of Bolivia, with comments on Xenopholis scalaris in Bolivia
    (Q15088586, 2009) Martin Jansen; Lucindo Gonzales Álvarez; Günther Köhler
    We describe a new species of Xenopholis from the Chiquitano Region in the eastern lowlands of Bolivia. The new species can be identified as member of the genus Xenopholis by its vertebral morphology. The new species differs from the other two species of Xenopholis in its unique, uniform dorsal color pattern. It further differs from X. scalaris by having two prefrontals and a narrow septum within each neural spine and perpendicular to its long axis. For X. scalaris we present new records from Bolivia, including the highest altitudinal record for the species and genus (Serranía Beu in the Pilón Lajas Reserve, Department of La Paz, 1500 m).

    (The Society for the Study of Amphibians and Reptiles, 2007) Martin Jansen; Lucindo Gonzales Álvarez; Günther Köhler
    We describe a new species of Hydrolaetare from the eastern lowlands of Bolivia. The new species differs from the other two congeners in (1) Finger II and III with lateral fringes only on the inner side; (2) relative length of first finger; (3) palmar tubercle distinctly larger than thenar tubercle; (4) toes semiwebbed; and (5) coloration. Moreover, the advertisement call of the new species differs from that of its congeners. Some information about its natural history is given.
