Identification
Charhyphus are small rove beetles distinguished by their compact body form and relatively short typical of Staphylinidae. The is characterized by features of the mouthparts and , though specific diagnostic characters require examination of male genitalia. Charhyphus brevicollis, the type species, has notably short pronotum relative to elytral length. Separation from related genera within Staphylinidae requires detailed morphological study; the genus has been historically placed in the subtribe Euaesthetina.
Distribution
Restricted to North America. Documented from the United States and likely extending into adjacent Canada. Charhyphus arizonensis occurs in Arizona. Charhyphus coeni has been recorded from Florissant, Colorado (fossil). Other have broader distributions across the United States.
