Systematics
Classification of the 46,275 (as of 1998) staphylinid species is ongoing and controversial, with some workers proposing an organization of as many as ten separate families, but the current favored system is one of 31 subfamilies, about 100 tribes (some grouped into supertribes), and about 3,200 genera. About 400 new species are being described each year, and some estimates suggest 3/4 of tropical species are as yet undescribed.
