Conolophus marthae, the Galápagos pink land iguana, is a species of lizard of the family Iguanidae. 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.
The 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.
A 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 specific 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.
Conolophus marthae is anatomically similar to the closely related species, Conolophus subcristatus. Both exemplify the typical saurian body shape, having squat, quadrupedal bodies with elongated tails. The legs sprawl out to the sides like all lizards, and a row of short spines runs down the middle of the lizard's back starting from the base of the neck to the tail. However, there are a few anatomical differences between the two species. The crest of C. marthae has been described as somewhat different from that of C. subcristatus. The most apparent difference is that of coloration – the body of C. marthae is pinkish with a few wide, vertical dark bands. This is a stark contrast from the yellow-brown coloration of C. subcristatus.
