Identification
Distinguished from other cerambycid by the combination of: large body size (exceeding 50 mm); short shorter than body; with multiple lateral spines including two enlarged spines and two ; with spines extending beyond ; association with hardwood root-boring . Differs from related prionine genera such as Mallodon and Derobrachus by the specific thoracic armature pattern and relatively shorter antennae.

Habitat
Associated with hardwood forests, particularly oak-dominated . Larval is subterranean, within living or dead roots of hardwood trees. habitat includes forested areas where trees occur.
Distribution
to Central America and the south-eastern United States.
Diet
Larvae bore into and feed on the roots of oaks (Quercus spp.) and other hardwood trees. feeding habits are not documented.
Host Associations
- Quercus - larval oak roots
- hardwoods - larval other hardwood tree roots
Life Cycle
Complete with root-boring larval stage. Specific details of -laying, larval instars, site, and longevity are not documented.
Behavior
Larvae are root-borers, tunneling within hardwood roots. are presumably or , as typical for many large cerambycids, though specific activity patterns are not documented.
Ecological Role
Larvae function as wood-boring decomposers or primary consumers of living hardwood roots, potentially contributing to tree stress or mortality in dense . May serve as a food source for subterranean .
Human Relevance
Potential pest of oak and hardwood trees in forestry and urban settings due to root-boring larval damage. Not documented as a significant economic pest. Large size makes conspicuous to collectors.
