Head rounded and slightly wider than the pronotum. Vertex broad and flattened, weakly inclined. Frontal rostrum slightly convex in frontal view, equal to the width of antennal scape. Antennal scape transversely broad, about 1.5 times as wide as length. Eyes slightly protruding, not extending beyond the head; ocellus three, lateral ocelli ovoid and distinctly larger than the median ocellus. Postclypeus narrowly banded, and slightly narrower in the middle than laterally; anteclypeus broader, apical narrowing; labrum shaped as a shield. Maxillary palpus five, the third and fourth segments equal in length, and the apical of the fifth segment distinctly widened; labial palpus three, the third segment being as long as the first two and widening at the end.

Forewings reaching the fifth abdominal segment, oblique veins six, the inner two slightly curved; chord veins three, second and third chord veins basally connected.

Posterior femur well developed, slightly shorter than the abdomen. Posterior tibiae equipped with spines on the one half of proximal portion (inside: 3-4; outside: 5) and spurs on distal part (inside: 4; outside: 4); basitarsus armed with two rows of small spines.
