(F and G) Malagasy blonde hognose snake (
Leioheterodon
modestus
).
Leioheterodon modestus
has also been extensively exported, and is the least
commonly available in the commercial snake trade. Thus, over-collection, in addition to
extensive habitat destruction, has raised the question of potential extinction of wild populations.
(H) Ringed hognose snake; boicora, nariguda falsa coral (
Lystrophis semicinctus
).
Some
members of the xenodontine dipsadid genus,
Lystrophis
, are popular in private collections,
and often termed “tricolor hognose snake,” or “South American hognose.” Zaher et al. (2009)
synonymized
Lystrophis
with
Xenodon
. There are no documented bites from this species.

Central and South American ground snakes (
Liophis
spp.).
The genus
Liophis
consists of some 40
species of xenodontine dipsadids that range throughout Central and
South America. Several taxonomic investigations have recommended differing reassignments for
these snakes (Curcio et al., 2009; Pinou et al., 2004; Vidal et al., 2010; Zaher et al., 2009). The
genus has been intermittently classified as
Leimadophis
, but recent review has recognized
