Troncoso-Palacios, Damien Esquerré, Félix A. Urra, Hugo A. Díaz, Carlos
Castro-Pastene, and María Soledad Ruiz (2018) Liolaemus is a particularly
species-rich radiation of New World iguanid lizards from southern South
America. Thanks to intense systematic and taxonomic research, the
knowledge on its species-level diversity has increased rapidly over the
past several years. The L. elongatus
species-complex has received considerable attention and a remarkable
case is Liolaemus chillanensis,
a name that has been used for two different species that are sympatric
in Termas de Chillán, central Chile. Since the holotype is lost, we
propose that the first step to identify the true L. chillanensis is through the
analysis of the original description. Then we provide a morphological
and molecular characterization of L.
chillanensis based on topotypes and a description of the taxon
previously confused with it. Key words: Chile, Cytochrome b, Liolaemus monticola, Phylogeny,
