摘要：Dipsadid snakes of the genus Sibynomorphus
are restricted to the South America and 12
species are currently recognized (Cadle 2007).
Sibynomorphus has a peculiar distribution, with
six species distributed along the Andean and
inter-Andean valleys of Peru and Ecuador and
the other species found south of the Amazon
in Argentina, Paraguay, Uruguay, Bolivia and
Brazil (Cadle 2007). In Brazil, four species have
been formally reported: S. mikanii, S. neuwiedi,
S. turgidus and S. ventrimaculatus (Peters 1960,
Peters and Orejas-Miranda 1986, Vanzolini 1986).
