The colored iguanas ( Polychrus ) are a genus of the iguanas (Iguania) that occur in Central and South America and on the islands of the Caribbean .
features
They are medium-sized and slender lizards, mostly green or brown in color. Her toes, in contrast to Anolis no prison slats at the bottom and are not broadened. Instead, they have graspable hands and feet similar to chameleons . The tail is also slightly graspable, but primarily serves to maintain balance. The males of most species have a colored throat flag that can be raised through the hyoid bone and is used in courtship and in threatening and imposing behavior between conspecifics. All colored iguanas are insectivores.
Systematics
Polychrus was first placed with the genus Anolis and other genera in the subfamily Polychrotinae in the family of the iguanas (Iguanidae) until the subfamily was raised to the rank of a family by Frost and Etheridge in 1989. In 2004 the same authors took six genera out of the family in a study of the internal systematics of the Polychrotidae and placed them in the newly established family Leiosauridae , so that now only Polychrus and Anolis with over 350 species belonged to the family. At the end of 2012, Anolis was assigned to the family Dactyloidae , so that Polychrus remained the only genus in the monotypical family Polychrotidae.
There are seven species within the genus Polychrus :
- Polychrus acutirostris Spix, 1825
- Polychrus femoralis Werner, 1910
- Polychrus gutturosus Berthold, 1846
- Polychrus jacquelinae Koch , Venegas, Garcia-Bravo & Böhme, 2011
- Polychrus liogaster Boulenger, 1908
- Polychrus marmoratus (Linnaeus, 1758)
- Polychrus peruvianus (Noble, 1924)
