It was first found in 1972 on the margins of the El Nihuil dam in San Rafael, Mendoza, Argentina. In November 2010, new specimens of lizards assignable to L. rabinoi were found in an area of large sand dunes, 10 km from where it had been searched for in vain for years.

A plant thought to be globally extinct has been rediscovered growing near a popular country walking route in Derbyshire, UK.  The  dandelion-like flower, the Leek-coloured hawkweed was discovered in Derbyshire in 1898 but not confirmed as a new species until 1942.  It disappeared from the area in the 1950s and died out at its only other site in Staffordshire some years ago.   There are more than 400 species of hawkweed in Britain.

Ecuadorian and British scientists have rediscovered one of the rarest amphibians of Ecuador, thought to have gone extinct more than three decades ago.  The Carchi Andean Toad (Rhaebo colomai) inhabits a small region in the border area between Ecuador and Colombia. The last time a specimen was observed in Ecuador was in 1984.  An expedition in July 2017 found a small population in the Dracula Reserve, in the northwestern Andes of Ecuador. The expedition was carried out by scientists from the Laboratory of Terrestrial Zoology of University San Francisco de Quito USFQ, the Natural History Museum of London, and the InstitutoRead More

New light has been shed on a misclassified vine species in the Ryukyu Islands of East Asia. This plant was first discovered in 1917 in Taiwan, when it was provisionally identified as Kadsura japonica. The plant was recently spotted again after 100 years, and further investigation proved that it was in fact a different species: Kadsura matsudae.

1953 was the last time any researcher saw a Cropan’s boa (Corallus cropanii) alive, which lives in Brazil’s Atlantic Forest south of São Paulo. Since then, the snake—thought to be the rarest boid in the world—has been recorded by scientists just five times. In January, a 1.7-meter-long female was captured by a group of rural workers in January.  The recently-captured boa is lucky: One of its captors was about to hack it to death, when the other two recalled “wanted signs” that had been posted by researchers from the University of São Paulo’s Museum of Zoology and the Butantan Institute,Read More

A monitor lizard lost to science in an 1800s shipwreck has been rediscovered on New Ireland, an island in Papua New Guinea. The medium-size monitor, Varanus douarrha, was first identified by French naturalist René Lesson in 1823. The specimen of the lizard collected by Lesson went down in a shipwreck off the Cape of Good Hope in 1824, however, so the monitor lizard was never systematically studied.  Varanus douarrha is now identified as a distinct from a the common mangrove monitor species (Varanus indicus) found all over New Guinea.

Unseen for more than 50 years, the New Guinea highland wild dog has at last been confirmed in its natural island habitat. Scientists are crooning over new pictures that confirm the survival of the New Guinea highland wild dog, which until now was feared to be extinct in its natural habitat on the South Pacific island Thought to be among the rarest species of canine, the highland wild dogs are either the same as or close relatives of the famous singing dogs of New Guinea, which exist only in captivity. More than a hundred camera-trap pictures taken in 2016 showRead More
