Four New Species of Water-Gliding Rove Beetles Discovered in Ningxia, China

Feb. 25, 2013 — Four new species from the Steninae subfamily of the large family of rove beetles (Staphylinidae) have been discovered in the Ningxia Autonomous Region, China, as part of an exploration of the insect fauna of the Liupan Shan Natural Reserve, where a large number of specimens has been collected. The expedition also yielded 11 new records for the Ningxia province of previously described Steninae species. The study was published in the open access, peer reviewed journal Zookeys.

The Ningxia Autonomous Region is mainly known as a dry, desert-like land. The region of the Liupan Shan Natural Reserve, however, is part of the Liupan Shan mountains, also known as the green pearl on the Loess Plateau. The area is also regarded as a "Kingdom of Animals" for its great biological diversity.

The rove beetle family, Staphylinidae, is one of the most widely distributed beetle families in the world. However, the representatives of the Steninae subfamily are of particular interest. These fascinating beetles are known for their unique ability to glide on the surface of water.This special skill is made possible through evolutionary adjustment allowing the production of special gland secretions that reduce surface tension.
