Identification
Aspidoglossa can be distinguished from related in the subtribe Ardistomina by combinations of elytral sculpturing, pronotal shape, and male genitalic characters. Species-level identification requires examination of microscopic features including the form of the , elytral and intervals, and the degree of pronotal constriction. The genus shares the general body plan of Clivinini: small to size, compact form, and often reduced or modified associated with subterranean habits.

Habitat
Members of this are ground-dwelling associated with soil . Based on the subtribal placement in Ardistomina, likely inhabit leaf litter, soil crevices, and other terrestrial microhabitats. The presence of Aspidoglossa subangulata in the United States suggests for temperate conditions, while Neotropical species occupy tropical and subtropical environments.
Distribution
Primarily Neotropical, ranging from Mexico through Central and South America. The northernmost extent is represented by Aspidoglossa subangulata in the southern United States. The has been documented across multiple countries including Mexico, Brazil, and other South nations based on epithets and original descriptions.
Ecological Role
As members of , likely function as or scavengers in soil and litter . The subtribe Ardistomina is known for burrowing , suggesting these contribute to soil aeration and through their movement through the substrate.
