Bolbocerosoma hamatum
Brown, 1929
Bolbocerosoma hamatum is a of earth-boring scarab beetle in the Geotrupidae. The species was described by Brown in 1929 and is found in the southeastern United States. Like other members of its , it is associated with burrowing in soil, though specific biological details remain poorly documented in the literature.

Identification
Members of Bolbocerosoma can be distinguished from related such as Eucanthus and Bolbocerastes by the structure of the male genitalia and the form of the tibiae. Specific identification of B. hamatum requires examination of these features and comparison with the original description by Brown (1929).
Habitat
Associated with sandy or well-drained soils in upland . Like other bolboceratine geotrupids, likely occurs in open woodlands, forest edges, and disturbed areas where suitable soil conditions for burrowing are present.
Distribution
Southeastern United States: Alabama, Florida, Georgia, and South Carolina.
Behavior
As an earth-boring scarab beetle, are presumed to excavate burrows in soil for larval development and adult shelter. The specific behavioral repertoire of this has not been documented.
Ecological Role
As a burrowing , likely contributes to soil aeration and nutrient cycling through its burrowing activities. The larvae probably develop in soil, feeding on organic matter or fungi, though this has not been confirmed for this .

Taxonomic History
Originally described by Brown (1929). The Bolbocerosoma was revised by Howden (1955), who provided the foundation for modern understanding of the group. The specific epithet "hamatum" is Latin for "hooked," though the precise referent is not clarified in the brief original description.
