Salient features of adults. Terrestrial.
Predacious (on small, usually immobile invertebrates), or blood-suckers. Tiny to small; 2–6 mm long (6 mm or less); fliers, or non-fliers; emitting repugnatorial liquid as a defence reaction; relatively stout bodied; not stilt-legged. Head non-linear. Rostrum clearly separated ventrally from the prosternum by a sclerotized gula; 3 segmented. Antennae longer than the head, readily visible from above; 4 segmented; non-aristate; with segments 3 + 4 less than twice as long as 1 + 2. Ocelli present. Metathorax with a scent-gland opening, comprising a funnel surrounded by a dull patch of elaborately sculptured cuticle, visible laterally on either side. Fore-wings well developed (mostly), or vestigial or absent; when macropterous, with a costal fracture and cuneus; of macropters, with a clavus. Tarsi 3 segmented; two-clawed. Claws all apical. Pulvilli absent. The abdomen without ventral silvery pubescence.
Small, flattened, elongate, soft-bodied bugs, with non-raptorial fore-legs; body hairs normal, by contrast with those of Cimicidae.
