Head capsule without prominent ocular tubercles; mandibles equipped with three pairs of parallel teeth; external margin of the mandible provided with long setae; apical tooth longer than the median tooth; labial palpi commonly four-articulated (three-articulated in some species), segments 2–4 shorter than the basal width of the mandible. Mesothoracic spiracles not raised on tubercle, abdominal spiracles inconspicuous. Thorax and abdomen equipped with sessile setiferous processes.
