Conolophus marthae
''Conolophus marthae'', the Galápagos pink land iguana, is a species of lizard of the Iguanidae family. It is native only to northern Isabela Island of the Galápagos. The iguana has a pink body with some dark stripes, prompting some to call it a pink iguana or the Galapagos rosy iguana. The species was first discovered in 1986 and was identified as a separate species, distinct from the Galapagos land iguana, early in 2009. This species is the only evidence of ancient diversification along the Galápagos land iguana lineage and documents one of the oldest events of divergence ever recorded in the Galápagos.
==Taxonomy and etymology==
Its generic name, ''Conolophus,'' is derived from two Greek words: ''conos'' (κώνος) meaning "spiny" and ''lophos'' (λοφος) meaning "crest" or "plume," denoting the spiny crests along their backs. Its tentative specific name ''rosada'' was derived from the Spanish word meaning "pink" in reference to the animal's pinkish body color. The term was later abandoned for the formal description and the species epithet, ''marthae,'' was chosen in memory of Martha Rebecca Gentile, the stillborn daughter of the describer Gabriele Gentile.〔
The species was first formally described in early 2009 as being distinct from the other island iguana populations. Genetic analysis of the pink morph subpopulation resulted in an identification of a genetically distinct and isolated population totally different from the other iguana species on the island. Further analysis suggested that this particular species diverged from its ancestral stock some 5.7 million years past.
