A new species of wildcat, discovered in Bolivia, has been formally identified after the accidental discovery of a lost kitten and nearly 10 years of painstaking research.
asserted
species → discover → research
The Leopardus tilcayo, which local people in the Bolivian Yungas, a band of cloud forest which runs along the eastern slope of the Andes, were aware of, was previously thought to be related to other wildcats in the region.

A study published in Current Biology this week has announced the first new cat species to be discovered in more than 100 years.
asserted
study → publish → years
The last was the pampas cat, reported in 1923.
asserted
last → report → 1923
Scientists have named the new cat Leopardus tilcayo, after the local Bolivian name for the animal.
asserted
Scientists → name → animal
The Leopardus tilcayo has been found living in the Bolivian Yungas, a band of cloud forest which runs along the eastern slope of the Andes, forming a transitional zone between the high mountains and the Amazon basin.
asserted
which → find → mountains
This is a rugged, humid and largely under-studied ecoregion, which spreads into Peru and northern Argentina, although so far the tilcayo has only been genetically confirmed in Bolivia.
asserted
tilcayo → study → Bolivia
Researchers don’t yet know whether the species is confined to a single pocket of this forest or spread more widely across it.
asserted
species → know → it
Jonas Lescroart, a researcher at the University of Antwerp and coauthor of the study, said such a discovery is rare for the cat family.
asserted
discovery → say → family
New species are sometimes “declared” when older scientific names are reinstated after genetic research shows a population was wrongly grouped with another species.
asserted
population → declare → species
That happened with the clouded tiger cat two years ago and the southern tiger cat, Leopardus guttulus, in 2013.
asserted
That → happen → 2013
“It had never been given a scientific name, and it had never been formally described in a scientific way that was published,” Lescroart told Al Jazeera.
asserted
Lescroart → give → Jazeera
“So we had the honour of coming up with a name for this animal and doing the formal scientific description.”

How was the cat found?

A local man found a kitten alone near the forest and, mistaking it for a stray domestic cat, brought it home to care for it.

It lived with his family for about a year until 2016 when its wild instincts became impossible to ignore, and it started chasing the neighbours’ chickens.
asserted
it → live → chickens
Once the family could no longer manage the cat themselves, they surrendered it to Senda Verde, a refuge for animals.
uncertain
they → manage → animals
The refuge called in biologist and lead scientist of the Bolivian Felids Research Program, Paola Nogales Ascarrunz, telling her they had found a “weird cat”.
asserted
they → call → cat
“Unfortunately, that’s the problem with the illegal wildlife trade,” Nogales Ascarrunz, told Al Jazeera.

Ascarrunz → ’ → Jazeera
“When you want to pet a wild animal, then you think the power of love is going to change the behaviour of this animal.
asserted
power → want → animal
But a wild animal, it doesn’t matter if you give him the best food, it’s not going to behave.”
asserted
it → matter → food
She added that this kind of case is common in Bolivia, particularly in the aftermath of wildfires, when orphaned young animals are captured and sold into the illegal pet trade before eventually being surrendered once new owners realise they can’t be kept.
asserted
they → add → trade
When she went to see the for herself, she says she found an animal with a small, scrunched face, short round ears, long whiskers, and covered in leopard-like spots – but clearly too large and too wild to be a domestic cat.
asserted
she → go → spots
Initially, she believed it was a Leopardus tigrinus, or tigrina, a small spotted cat found across much of Central and South America.
asserted
it → believe → America
But, she says, something about the size and shape of the cat’s spots bothered her.
asserted
something → say → her
It would take nearly a decade, a genetics collaboration spanning three countries, and DNA pulled from century-old museum skulls to prove she was right to be suspicious.
asserted
she → take → skulls
Perhaps leopards can’t change their spots but apparently, you can discover a new Leopardus with new spots altogether.
asserted
you → change → spots
How was it found to be a new species?
asserted
it → find → ?
While Nogales Ascarrunz was puzzling over her “weird cat” in Bolivia, an entirely separate effort was under way to study tiger cats across the continent.
asserted
effort → puzzle → continent
Lescroart and co-researchers in Belgium, Brazil, Bolivia, the United States, Colombia, the United Kingdom and Peru were busy collecting tiger cat DNA from across South America to resolve a long-standing taxonomic puzzle.
asserted
Lescroart → collect → puzzle
“The group of tiger cats has always been a contentious group with an uncertain taxonomy, and no one could really tell with certainty how many different species of tiger cats there were walking around,” Lescroart said.
uncertain
Lescroart → tell → cats
By combining existing genomic data from northeast Brazil, Colombia and southern Brazil with new samples from the Guianas, Peru and Bolivia, the team built a far more complete picture of the group than had existed before, ultimately identifying five distinct species rather than the two to four previously expected.
asserted
team → combine → four
Lescroart said the results were surprising.
asserted
results → say → ?
“When I started working on tiger cats, I was already aware from the start that, regardless of the results, something would have to be rearranged … but we would never have expected to find a completely undescribed species.”
asserted
we → start → species
Because tiger cats are what scientists call a “cryptic species” group, nearly identical in appearance but genetically distinct, the differences were essentially invisible without DNA analysis.
asserted
differences → call → analysis
“Physically, they are very similar and hard to tell apart at first instance,” Lescroart said, “and you need genetic research to dig down and find that there are important differences.”
asserted
you → tell → research
“When we managed to put our data together, that is when the pieces clicked,” Lescroart said, “and we realised that the one in Bolivia is really a separate thing from the other tiger cats that we already had on our radar as suspected species or subspecies.”
asserted
we → manage → species
