Phyllodrepa humerosa

Members of Phyllodrepa are small, slender rove beetles with relatively long antennae and reduced elytra typical of Staphylinidae. Phyllodrepa humerosa may be distinguished from congeners by subtle differences in pronotal and elytral proportions, though definitive identification requires examination of male genitalia or reference to original species descriptions. The specific epithet "humerosa" suggests notable shoulder (humeral) features on the elytra.

Collection records indicate association with forested environments, particularly deciduous and mixed woodlands. Specimens have been recorded from leaf litter and decaying wood, consistent with the general ecology of Omaliinae.

Eastern North America: Canada (Alberta, New Brunswick, Nova Scotia, Ontario, Quebec) and United States (Connecticut, District of Columbia, Florida, Iowa, Illinois, Indiana, Kansas, Kentucky, Maryland, Maine, Michigan, Missouri, North Carolina, New Hampshire, New Jersey, New York, Oklahoma, Pennsylvania, Virginia, Vermont, Wisconsin).

Presumed to function as a decomposer in forest floor ecosystems, based on family-level characteristics of Omaliinae and documented microhabitat associations.

• Phyllodrepa floralisOverlaps in geographic range and shares general habitus; requires careful examination of external morphology and male genitalia for separation.
• Other Omaliinae genera (e.g., Olophrum, Eusphalerum)Similar small size and habitat preferences; distinguished by antennal structure, pronotal shape, and elytral proportions.
