Uloma mentalis
Horn, 1870
Uloma mentalis is a darkling beetle in the Tenebrionidae, described by George Henry Horn in 1870. It belongs to the Uloma, a group of small to medium-sized beetles associated with decaying wood and forest floor . The species is known from limited observations in North America, with confirmed records from Ontario, Canada. As with many tenebrionid beetles, its is poorly documented in the scientific literature.

Identification
Members of the Uloma are generally recognized by their convex, oval body shape and short, clubbed . Uloma mentalis can be distinguished from by subtle differences in pronotal and elytral , though precise diagnostic features require examination of . The name 'mentalis' may refer to distinctive features of the or mouthparts, though this etymology is not confirmed in available sources. Positive identification typically requires comparison with voucher specimens or original description.
Habitat
Based on -level associations and limited distribution data, Uloma mentalis likely inhabits forested environments, particularly areas with decaying hardwood logs and accumulated woody debris. Tenebrionidae in this ecological guild are commonly found in moist, shaded microhabitats under bark or within rotting wood.
Distribution
Confirmed records from Ontario, Canada (ISO 3166-2:CA-ON). The full extent of its range is unknown; additional may occur in the northeastern United States given the distribution patterns of related Uloma .
Ecological Role
As a member of the Tenebrionidae, Uloma mentalis likely contributes to wood decomposition and nutrient cycling in forest . This functional role is inferred from -level ; direct observations of this are lacking.
