Is it a squirrel? A rat? A Guinea pig? Try none of the above.

NEW YORK (MAY 11, 2005) — A team of scientists working in Southeast Asia have discovered a long-whiskered rodent with stubby legs and a tail covered in dense hair. But don’t call it a squirrel. Or a rat. Because it’s actually more like a guinea pig or chinchilla. But not quite. In fact the new species, found in Laos by scientists from the Wildlife Conservation Society (WCS) and other groups, is so unique it represents an entire new family of wildlife.
The new species is described in the recent issue of the journal Systematics and Biodiversity by authors from WCS, The Natural History Museum in London, University of Vermont and WWF Thailand.
Called Kha-Nyou by local people, the species was discovered by WCS researcher Dr. Robert Timmins in a hunter’s market in Central Laos. WCS is working in Laos to help enact an aggressive program designed to halt illegal wildlife trade where poaching has devastated animal populations.
“It was for sale on a table next to some vegetables. I knew immediately it was something I had never seen before,” said Dr. Timmins. Dr Mark Robinson, working with WWF Thailand later discovered other specimens caught by hunters, and also identified bone fragments in an owl pellet. Based on morphological differences in the skull and bone structure, coupled with DNA analysis, the authors estimate that the Kha-Nyou diverged from other rodents millions of years ago.
“To find something so distinct in this day and age is just extraordinary. For all we know, this could be the last remaining mammal family left to be discovered,” Dr. Timmins said.

Very little is known about the Kha-Nyou, other than it seems to prefer areas of limestone outcroppings and forest cover, and it appears to be a nocturnal vegetarian. It also gives birth to one offspring at a time, rather than a litter.
Dr. Timmins, who also discovered a new species of striped rabbit from the same region in 1999, warns that habitat protection and regulations to reduce unsustainable commercial hunting are vital to safeguarding remaining populations of the Kha-Nyou and a gallery of other unusual species.
“Skeptics might say that if we are still discovering such amazing new animals, why are people worried about wildlife loss; but of course it is an indication of how little we know, and a window onto what we could be losing without ever knowing,” said Dr. Timmins.

About the Wildlife Conservation Society
The Wildlife Conservation Society saves wildlife and wild lands. We do so through careful science, international conservation, education, and the management of the world’s largest system of urban wildlife parks, led by the flagship Bronx Zoo. Together, these activities change individual attitudes toward nature and help people imagine wildlife and humans living in sustainable interaction on both a local and a global scale. WCS is committed to this work because we believe it essential to the integrity of life on Earth.
Conservation in Laos – from mongabay.com
Conservation in Laos faces considerable obstacles not only from increased interest in mining but also due to rampant deforestation from slash-and-burn agriculture, uncontrolled fires, illegal logging, and fuelwood collection. The strongly-centralized approach to conservation — Laos is a communist country — may may spawn animosity at toward conservation efforts at a local level if initiatives fail to account for local needs.
Despite these hurdles, there is hope for conservation in Laos. In an effort to protect the country’s species richness, Laos recently established 18 National Biodiversity Conservation Areas including one known as Nakai Nam Theum National Biodiversity Area in the mountainous border area near Vietnam. During the 1990s researchers in this protected area discovered a new genus of cattle-like mammal along with two deer-like species.
