Researchers have discovered eight new gecko species in the forests of Madagascar. The researchers apparently discovered the eight new species while studying the brown Lygodactylus geckos of the subgenus Domerguella. This lizard has been studied for decades. They had specifically been focusing upon the distribution and evolution of the species, thinking there were five subspecies within the subgenus. Now, based on DNA analysis and the the study of these lizards scales and the proportions of scales on their bodies, the researchers believe there may be as any as 17 new species, but have definitively named eight new species.
“The Lygodactylus madagascariensis species group, constituting the subgenus Domerguella, currently contains five valid species of inconspicuous dwarf geckos from Madagascar’s humid forests, but at least 18 deep genetic lineages have been revealed by recent molecular studies,” the researchers wrote in their paper describing the new species. “Given the high morphological similarity of these lineages, taxonomic resolution of this astonishing diversity requires efforts to correctly delimit species, as well as assigning the available nomina to the species-level lineages identified.”
Eight Lygodactylus Species New To Science
The new species are Lygodactylus salvi sp. nov., found in the Sambirano region in northern Madagascar; L. tantsaha sp. nov. which occurrs sympatrically with L. madagascariensis and L. petteri on Montagne d’Ambre in northern Madagascar; L. roellae sp. nov. ) known for its striped coloration, also from northern Madagascar; L. winki sp. nov., which lacks stripes and from northern Madagascar. This species belongs to a subclade found in the eastern rainforests of the island; L. ulli sp. nov., a species from the same subclade as L. winki but known only from the Marojejy Massif in the North East; L. fritzi sp. nov., a species of this subclade that occurs in coastal lowlands in the Northern Central East; L. hodikazo sp. nov., known from a single specimen collected at the Tsingy de Bemaraha. This lizard is the only known Domerguella species known from the West region of Madagascar; and L. hapei sp. nov. , an enigmatic species from the Sambirano region that is identified by a striped pattern on the throat.
