Salient features of adults. Terrestrial.

Phytophagous (commonly on plants with secretory hairs). Small to large; 6–16 mm long; fliers (usually), or non-fliers; relatively stout bodied, or with narrow-elongate bodies; not stilt-legged; without conspicuous dark-and-pale banding of antennae and legs. Head non-linear. Rostrum clearly separated ventrally from the prosternum by a sclerotized gula; 4 segmented. Antennae from the upper part of the head; longer than the head, readily visible from above; 4 segmented; non-aristate. Ocelli present. Scutellum relatively small. Metathorax without laterally visible scent gland openings (or these very reduced). Fore-wings well developed (mostly), or conspicuous, but much shorter than the abdomen; differentiated into a basally thickened and a distally membranous region; with a clavus. Membrane of the hemelytron with numerous veins reaching or almost reaching the margin. Tarsi 3 segmented. The abdomen without ventral silvery pubescence. The second dorsal abdominal scent gland aperture displaced forwards into the fifth tergite, thus close to that of the first gland.

Last antennal segment neither expanded nor darkened.
