Synonyms and other taxonomic changes
see(1)(2)(3) for major taxonomic changes not reflected in(4)
Numbers
the largest and the most difficult staphylinid lineage, with >12,000 described spp. in 52 tribes and over 1,000 genera worldwide, but the true global diversity is much greater; in our area, ca. 1,400 described spp. in >180 genera arranged in 21 tribes(4)
Size
<1-10 mm, mostly 3-5 mm(4)
Identification
tarsal formula is critical to identification of genera; 70-100X or higher magnification is recommended(4)
due to the lack of comprehensive keys, in most cases even a staphylinid specialist is unable to identify the vast majority of aleocharines from most geographic regions even to genus, much less to species
identification guide covering nearly all of the species found in eastern Canada(5)
Range
throughout the world
Habitat
virtually all terrestrial habitats
