Sedges and various grasses (Chiasson, 1986).
Apex of the antennal segment 2 is not produced along the outer margin, and is approximately symmetrical. Antennal segment 4 has a simple sense cone, and segment 3 is shorter than 5. The pronotum is distinctly broader than long. The outer distal edge of the fore femur is strongly reflexed, and looks like a curved tooth when viewed dorsally (Zur Strassen, 1960). Males are micropterous (Mound et al., 1976). The hind margins of the abdominal tergites have a dentate border. Glandular areas on the abdominal segments of males are transversely elongate (Zur Strassen, 1960).
