The Osoriinae are a subfamily of beetles in the family Staphylinidae, the rove beetles. They are found mainly in tropical and subtropical regions. [1]
The abdomen is flattened and has parallel sides. A suture along each side or the abdomen may be made up of fused plates. [2]
Little is known about the biology of this subfamily. Species may be found in leaf litter, under bark, or in ant nests. They are detritivores and fungivores. [2]
Staphylinoidea is a superfamily of beetles. It is a very large and diverse group with worldwide distribution.
Stenus is a genus of semiaquatic rove beetles in the subfamily Steninae, and one of the largest genera in the kingdom Animalia, with some 2700 known species worldwide. They are predators of Collembola and other small arthropods. Adults have a protrusible labium with a sticky tip used in prey capture. To overcome the rapid escape of Collembola, the labium is protruded at high speed by hemolymph pressure, and immediately withdrawn, pulling the prey within the range of the mandibles. However, the labium tip does not easily stick to prey covered in scales or setae or that have a large body size. Stenus comma is more likely to catch such prey by lunging forward and grabbing them directly with its mandibles rather than using its labium. Stenus species are also known for "skimming" on the water surface using their pygidial gland secretions that act as a surfactant and rapidly propel the beetle fast forward, a phenomenon known as the Marangoni effect. Stenus comma has been seen to achieve a velocity of 0.75 m/s, and to cover a distance of up to 15 m if the secretion is continuous.
Ocypus is a genus of rove beetles in the subfamily Staphylininae.
The Aleocharinae are one of the largest subfamilies of rove beetles, containing over 12,000 species. Previously subject to large-scale debate whether the subfamily deserved the familial status, it is now considered one of the largest subfamilies of rove beetles.
Lomechusini is a tribe of rove beetles. It is generally small, but includes some fairly large genera such as Zyras.
