Eyes small, entire. Elytral striae nine or more, without scutellary striole. Wing with radial cell absent, large apical membrane and reduced posterior venation. Mesepimeron not reaching mesocoxal cavities. Tarsomeres not expanded or lobed. Abdomen with membrane visible after ventrites 3 and 4, hinging tenebrionoid. Defensive glands absent.
