Biodiversity of the family Leiosauridae








Genus
Leiosaurus

Typical Smooth Iguanas*

Typische Seidenleguane*

Typiske Silkeleguaner*

1837 Leiosaurus Dumeril & Bibron (type species: Leiosaurus bellii Dumeril & Bibron 1837)
1847 Liosaurus Agassiz [substitute name for Leiosaurus Dumeril & Bibron 1837]
1897 Aperopristis Peracca (type species: Aperopristis paronae Peracca 1897; syn. Cei 1986)
Contents: 4 species, all of which are endemic.
Remarks: Previously included Pristidactylus fasciatus and P. bardensis (now a synonym of fasciatus). Cei (1973) revalidated the genus Aperopristis for the species catamarcensis and paronae, but later transfered them back to Leiosaurus (Cei 1986). Frost, Etheridge, Janies & Titus (2001) again regarded Aperopristis as a valid genus.
Distribution: Argentina.

Leiosaurus bellii

Southern Smooth Iguana*

Südlicher Seidenleguan*

Sydlig Silkeleguan*

1837 Leiosaurus bellii Dumeril & Bibron
Liosaurus bellii Boulenger 1885

Distribution: Argentina.


Leiosaurus catamarcensis

Catamarca Smooth Iguana*

Catamarca-Seidenleguan*

Catamarca-silkeleguan*

1898 Liosaurus catamarcensis Koslowsky
Aperopristis catamarcensis Müller 1922
Leiosaurus catamarcensis Libermann 1939

Remarks: Cei (1973) revalidated the genus Aperopristis for the species catamarcensis and paronae, but later transfered them back to Leiosaurus (Cei 1986).
Distribution: Argentina.


Leiosaurus jaguaris

Jaguar Smooth Iguana*

Jaguar-Seidenleguan*

Jaguar-silkeleguan*

2007 Leiosaurus jaguaris Laspiur, Acosta & Abdala

Distribution: Argentina.


Leiosaurus paronae

Mendoza Smooth Iguana*

Mendoza-Seidenleguan*

Mendoza-silkeleguan*

1897 Aperopristis paronae Peracca
Leiosaurus paronae Gallardo 1961

Remarks: Cei (1973) revalidated the genus Aperopristis for the species catamarcensis and paronae, but later transfered them back to Leiosaurus (Cei 1986). Frost, Etheridge, Janies & Titus (2001) again regarded Aperopristis as a valid genus. The type locality ("Brazil") is apparently the only indication that paronae is found in the country. No precise Brazilian localities seem to have been recorded, so the presence of the species in the country is regarded herein as unconfirmed.
Distribution: Argentina.
