Euconnus salinator
(J.L.LeConte, 1852)
Euconnus salinator is a minute rove beetle in the Staphylinidae, Scydmaeninae. Members of this are among the smallest beetles, often measuring under 2 mm. The has been recorded across eastern North America from Canada to Florida. Scydmaenine beetles are primarily associated with leaf litter and soil where they prey on oribatid mites.

Identification
Euconnus are distinguished from other Scydmaeninae by their compact body form and distinctive antennal club. E. salinator can be separated from by subtle differences in pronotal and elytral , though precise identification requires microscopic examination and comparison with type material. The species name 'salinator' refers to salt-marsh or saline , though this may reflect collection circumstances rather than habitat preference.
Habitat
Specimens have been collected in leaf litter and soil . The specific epithet suggests possible association with saline or coastal environments, though records span inland localities as well.
Distribution
Eastern North America: Canada (Manitoba, New Brunswick, Ontario) and USA (Connecticut, District of Columbia, Florida, Iowa, Illinois, Massachusetts, Maryland, Maine, Michigan, New Hampshire, New York, Pennsylvania, Rhode Island, Tennessee, Vermont, Wisconsin).
Similar Taxa
- Other Euconnus speciesMorphologically similar; require examination of male genitalia and fine surface for definitive separation.
- Other Scydmaeninae generaDistinguished by antennal structure, body proportions, and presence/absence of elytral .

Taxonomic note
The specific epithet 'salinator' (Latin: salinator, salt- or salt-dealer) is unusual for a and may refer to the type locality or collector's circumstances rather than . The was described by John L. LeConte in 1852.
Collection rarity
With only 4 iNaturalist observations and scattered museum records, this is rarely encountered by general collectors, likely due to its minute size and cryptic habits rather than true rarity.
