NEW YORK (AFP) – New Yorkers are used to fighting each other for space, but there may be a new contender in town according to a Rockefeller study that appears to have uncovered a new species of cockroach.

"The cockroach is genetically modified. Species don't differ more than one percent, this cockroach is four percent different, which suggests it is a new species of cockroach," Professor Mark Stoeckle, an expert on genomics and DNA barcoding at Rockefeller University, told AFP.

"We think that the museums of natural history in Paris or New York could be interested." The previously unidentified creepy-crawly was uncovered as part of a project undertaken by two high-school students, Brenda Tan, 17, and Matt Cost, 18, under Stoeckle's supervision.

In their roles as "DNAHouse investigators," the pair trawled New York apartments, stores and street, collecting 217 specimens between November 2008 and March 2009.

They took samples from supermarket food, the remains of an insect found in a box of fruit, a feather from a duster, dried dung and a cockroach and matched DNA sequences using the Barcode of Life Database and GenBank.
