The Top 10 New Species

Group Touts 10 Wild New Species

Thousands of new plant and animal species were discovered in 2007, though only 10 were bizarre enough, lethal enough or just plain cool enough to garner spots on a new Top-10 list. Each year, the International Institute for Species Exploration (IISE) at Arizona State University issues the Top 10 New Species list(see below image), which spotlights flora and fauna described during the previous year, so in this case 2007. The new list includes lethal animals like a box jellyfish (Malo kingi) — named after Robert King, who apparently died after he was stung by this species — and the Central Ranges Taipan (Oxyuranus temporalis), now thought to be one of the most venomous snakes in the world. And a dragon millipede, whose shocking-pink exterior would put a 1980s fashionista to shame, gets a spot on the list. Rather than setting trends, the arthropod uses its gaudy coloration to alert predators of its toxicity. Some species made it onto the list due to their modern monikers, including the Michelin Man, a succulent plant from Western Australia that resembles the rotund tire guy. Also on the list: an ornate sleeper ray from the east coast of South Africa that was named after the Electrolux vacuum cleaner brand due to the animal's ability to suck up prey in the water. While scientists discover thousands of species each year, with an estimated 16,969 species considered new to science in 2006, plenty of plants and animals are waiting to be found. Scientists estimate 10 million or so species exist on Earth, with 1.8 million species described since Carl Linnaeus developed the modern system for naming plants and animals in the 18th century. "Most people do not realize just how incomplete our knowledge of Earth's species is or the steady rate at which taxonomists are exploring that diversity," said Quentin Wheeler, an entomologist and director of IISE. The international committee was chaired by Janine Caira of the University of Connecticut, and included scientists from across the globe, including the United States, United Kingdom, South Africa, Spain and New Zealand.

The Top 10 New Species

1



Electrolux addisoni
This new genus and species is the largest known member of the electric ray family Narkidae, and made the Top 10 because of its unusual and amusing generic name. According to the authors: "The name alludes to the well-developed electrogenic properties of this ray (collectors and photographers have experienced the shocking personality of this bold, active and brightly patterned electric ray first-hand), the discovery of which sheds light (Latin, lux) on the rich and poorly known fish diversity of the Western Indian Ocean. And the vigorous sucking action displayed on the videotape of the feeding ray that was taken by Stephania and Peter Lamberti may rival a well-known electrical device used to suck the detritus from carpets, furniture, and other dust-gathering surfaces in modern homes."

Gryposaurus monumentensis
This new dinosaur species was discovered by a team from Alf Museum, the only nationally-accredited paleontology museum on a high school campus. It is one of the most robust duck-billed dinosaurs ever found, and probably the largest dinosaur in the 75 million-year-old Kaiparowits Formation fossil ecosystem.




3



Desmoxytes purpurosea
Millipedes (relatives of centipedes) are highly variable in appearance and coloration, but this shocking pink stands apart. The authors suggest that its gaudy coloration and habits (it sits openly on the ground and vegetation during the day) probably indicates to would-be predators that it is not edible (spiny and toxic).




4



Philautus maia
This species was described from a single female museum specimen collected around 1860. It and a number of related species from Sri Lanka are almost certainly now extinct. Its discovery demonstrates the importance of museum specimens in determining baseline information on biodiversity and in documenting the natural heritage of nations. Had this specimen not been collected in the 19th century, it would possibly have never been known.



5





Oxyuranus temporalis
This is perhaps one of the most venomous known snake species. Its two closest relatives, the inland taipan (or fierce snake) and the coastal taipan, are ranked first and third most venomous snakes in the world, respectively. The discovery of the new species (known only from a single specimen) highlights how little is known of even relatively large animals in harsh, poorly collected habitats (in this case an isolated arid region of Australia). It also emphasizes the need for accurate taxonomy of venomous species for proper treatment of bites.



6



Styloctenium mindorensis
This large and charismatic fruit bat species is known only from the Philippine island of Mindoro. It is only the second known species in the genus; the other species is known only from the Indonesian island of Sulawesi and nearby Togian Islands, and was originally discovered (and named after) Alfred Russell Wallace. Wallace was a colleague of Charles Darwin and coauthor of their famous paper On the Tendency of Species to form Varieties; and on the Perpetuation of Varieties and Species by Natural Means of Selection. Among other important contributions, he noted the distinctive faunal break separating Asian and Australian biotas, which is now known as Wallace's Line. Ironically, the new species occurs on the west side of Wallace's Line whereas its sister species is on the east side. The new species is threatened by habitat loss and hunting. Its discovery highlights an increasing understanding of endemism on Mindoro, and the need for species exploration and conservation.



7



Xerocomus silwoodensis
This new mushroom species was discovered on Silwood Campus, a campus of Imperial College, London, although it is also found elsewhere (two additional sites in England and one each in Spain and Italy). The discovery of a new species in one of the most intensely studied floras in the world and on the campus of a leading education center for biologists illustrates how poorly species are known.


8



Malo kingi
The new species is the second known species of the dangerous box jellyfish genus Malo, one of several genera of irukandji jellyfish. It is named after American tourist Robert King, who apparently died after being stung by the species while swimming off northern Queensland, Australia. King's death was a pivotal point in irukandji management, raising public awareness about safety.



9



Megaceras briansaltini
Rhinoceros beetles are named for the horn-like structures on their heads. According to the author, this charismatic new species has a unique form of horn that is otherwise similar only to the one on Dim, the blue rhinoceros beetle in the Disney/Pixar animated film "A Bug's Life." This makes for a rare instance of Nature imitating art.




10



Tecticornia bibenda
This new species made the Top 10 because of its charismatic appearance; according to press releases, it looks like the Michelin Man™. It has been also the subject of media releases on the lack of support for taxonomic work in Western Australia, a biodiversity hotspot. There is a huge backlog of new plant species awaiting description, ironically generated by environmental impact surveys for mining companies. It is one of 298 new plant species described from Western Australia in 2007.
