Prosternum: prosternal process not dilated at apexapex:
end of any structure distad to the base
, procoxal cavities open posteriorly, rarely closed posteriorly. 
ElytraElytron:
the leathery forewing of beetles, serving as a covering for the hind wings, commonly meeting opposite elytron in a straight line down the middle of the dorsum in repose

cut off squarely at the tip

in larval and adult insects, paired segmented appendages, borne one on each side of the head, functioning as sense organs and bearing a large number of sensilla
with second segment nearly as long as third, following segments transversetransverse:
broader than long
. Pronotumpronotum:
the upper and dorsal part of the prothorax
globular, widest at about middle; posterior coxae prominent. Legs moderately robust; anterior tibiaetibia:
the leg segment distal to the femur, proximal to the tarsus

Differential diagnosis

The second antennal segment almost as long as the third will distinguish this genus from Spondylis and Neospondylis.

Distribution

Nearctic: southeastern United States from Florida to New Jersey and Arkansas

Recorded host plants

Pinus spp.

Remarks

1 species. Likely a rootborer of conifers in sandhill habitat.
