his corrections (1967,

and a discussion of each subfamily. Key

In both species and genera, members
of this difficult subfamily comprise at least two-fifths of all
Staphylinidae. There are no satisfactory keys to the genera of America north
of Mexico. Key

A single genus, Oxyporus Fabritius, comprises this subfamily. It was
revised by Campbell (1969). |
