 The Panay cloudrunner was discovered by western science in 1987, and was described as a new species in 1996 by Robert Kennedy of the Cincinnati Museum of Natural History and Pedro Gonzales of the National Museum of the Philippines.The late date of discovery was because the lack of forest cover on Panay which led to the island being largely ignored by biologists.The Panay cloudrunner is a little over 600 mm long, with grizzled greyish-brown fur and a long, bushy tail making up more than half of the body length.
