    FIRST RECORD OF Punomys (RODENTIA: SIGMODONTINAE) IN BOLIVIA
    (2011) Jorge Salazar‐Bravo; Jacqueline Miralles-Salazar; Adriana Rico‐Cernohorska; Julieta Vargas
    "We report the first known specimen of the cricetid genus Punomys for Bolivia based on an adult female captured in 1987. The specific affinities of this individual are currently unknown as it shares qualitative and quantitative characters with Punomys kofordi and P. lemminus, but also differs substantially from both species; we submit that new specimens are required to arrive to a definitive conclusion as to what species this specimen represents."

    First record of Rhagomys (Mammalia: Sigmodontinae) in Bolivia
    (Smithsonian Institution, 2006) Gabriela Villalpando; Julieta Vargas; Jorge Salazar‐Bravo
    A recent monograph on the biological diversity of Bolivia concludes that the country is megadiverse (Ibisch and Merida, 2003); this statement is especially true for mammals. Despite being a landlocked country and representing only 6% of the geographic area of South America, Bolivia harbors the 4th mostdiverse mammalian fauna of the continent (Ceballos and Simmonetti, 2002). However, the country remains poorly explored, as reports of new taxa for science or the country have recently been published (Pacheco et al., 2004; Rios-Uzeda et al., 2004; Solmsdorff et al., 2004; Emmons and Patton, 2005). These new records and species, coupled with further advances in the taxonomy and systematics on Neotropical mammals have rendered sections of Anderson’s book Mammals of Bolivia (Anderson, 1997) obsolete in less than a decade after its publication. Accordingly, in this paper, we report a new genus and species of mammal for the fauna of Bolivia. Measurements of the animal followed Luna and Patterson (2003) except for greatest length of skull (GLS), taken to be represented by the occipito-nasal length, and CML (Condylomolar length), which was not measured because it was not defined either by Luna and Patterson (2003) or any of the references cited therein (Myers et al., 1990; Voss, 1991 or Musser et al., 1998).

    Un registro nuevo de Atractus boettgeri (Serpentes: Colubridae), con comentarios sobre la taxonomía e historia natural de la especie
    (National Autonomous University of Mexico, 2010) Jorge Salazar-Bravo Salazar-Bravo; Julieta Vargas; Agustín Jiménez-Ruiz; Jay M. Savage
    Se reporta una extensión de en la distribución de la especie Atractus boettgeri, una serpiente endémica de Bolivia. Esta especie se diferencia de A. taeniatus por tener un número segmental muy por encima del intervalo descrito para A. taeniatus y por tener sólo 6 dientes maxilares, en vez de 8-9 en A. taeniatus. Además, A. boettgeri se diferencia de A. emmeli por tener escamas supralabiales en patrón 6-6 (en vez de 7-7) y tener un conteo de escamas ventrales menor en hembras (175-177 versus 181-189). Incluyendo éste, todos los registros conocidos para A. boettgeri parecen estar asociados con la vegetación del Cerrado en Bolivia. El ejemplar se encontró en el estómago del tatú común (Dasypus novemcinctus).
