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,
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

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 "
" for its
great biological diversity. Kingdom
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.
