The Steninae are a subfamily of the Kurzflügler ( Staphylinidae ), which only includes the two genera Stenus and Dianous .

Physique and lifestyle

The Steninae have the slim physique typical of most Staphylinidae with short elytra and an unprotected, but very flexible abdomen . This habitus gives the animals the ability to develop gap systems as a habitat and thus enables them to occupy new niches. In order to compensate for the disadvantage of an unprotected abdomen, the Steninae , like many other Staphylinidae , have abdominal defensive glands which produce potent chemical defense substances .

The animals can be found on the banks of standing and flowing water, in wet meadows, moors, as well as in compost heaps and genist.
